Dengue Is Spreading: Is Warmer Weather to Blame?
American Society of Microbiology, Bugs and Drugs
As of 2024, dengue, a mosquito-borne disease that typically occurs in tropical and subtropical regions of the world, is chief among these migrating vector-borne diseases. From Jan. 1-June 24, 2024, dengue has caused record-breaking numbers of cases worldwide. Over 10 million cases and 5,000 dengue-related deaths have been reported by 80 countries and territories around the world since the beginning of 2024—most of these concentrated in the World Health Organization (WHO) Pan American Health…
As of 2024, dengue, a mosquito-borne disease that typically occurs in tropical and subtropical regions of the world, is chief among these migrating vector-borne diseases. From Jan. 1-June 24, 2024, dengue has caused record-breaking numbers of cases worldwide. Over 10 million cases and 5,000 dengue-related deaths have been reported by 80 countries and territories around the world since the beginning of 2024—most of these concentrated in the World Health Organization (WHO) Pan American Health Organization (PAHO) region. According to a health advisory that was released by the CDC on June 25, 2024, this is approximately double the number of cases that were observed in all of 2023. Some basic knowledge about the virus and how it is transmitted can help us better contain this ongoing threat.

Measles Cases Continue to Rise in the US Could the US lose its measles elimination status?
Today's Clinical Lab
Measles is caused by the measles virus, a single-stranded, negative-sense, enveloped RNA virus of the genus Morbillivirus within the family Paramyxoviridae. Measles is a highly contagious, vaccine-preventable infectious disease.

Measles is a highly contagious, vaccine-preventable infectious disease.
Illustration rendering of the measles virus particle.
This illustration provides a 3D graphic representation of a spherical-shaped measles virus particle studded with glycoprotein tubercles. Colorized in maroon, tubercular studs are known as hemagglutinin (H)-proteins, while those colorized gray represent fusion (F)-proteins. F-proteins are responsible for the fusion of the virus and host cell membranes, viral penetration, and hemolysis. The H-protein is responsible for the binding of virions to cells. Both types of proteinaceous studs are embedded in the particle envelope’s lipid bilayer.
CDC PHIL / ALLISON M. MAIURI, MPH, CHES ID# 21074
For most countries, the recommendation is that children be immunized against measles at 12 months, generally as part of a three-part MMR vaccine (measles, mumps, and rubella). Waiting to vaccinate an infant until 12 months of age is necessary to ensure the immune system can adequately respond to the vaccine to produce immunity. Further, children between the ages of four and five are given a second dose of the vaccine to increase rates of immunity. -

Workforce in the Shadow of Healthcare –An Update on the Survival Status of Laboratory Medicine and Public Health
Biomed J Sci & Tech Res 54(5)-2024. BJSTR. MS.ID.008604
Most of society by now are at least somewhat aware of the severe shortages of frontline nurses and doctors. Workforce shortages were here even before the pandemic – but now, like most professions, the
healthcare and public health workforce shortage has reached dangerously low staffing levels. In a recent 2023 Definitive Healthcare report, the authors state that since 2020, nearly one in five healthcare workers have quit their jobs, and research suggests that up to 47% of healthcare workers…Most of society by now are at least somewhat aware of the severe shortages of frontline nurses and doctors. Workforce shortages were here even before the pandemic – but now, like most professions, the
healthcare and public health workforce shortage has reached dangerously low staffing levels. In a recent 2023 Definitive Healthcare report, the authors state that since 2020, nearly one in five healthcare workers have quit their jobs, and research suggests that up to 47% of healthcare workers plan to leave their positions by 2025. The U.S. is suffering from a significant healthcare worker shortage, and the data
shows that this is going to have near-term and long-term effects on patient care and safety, and hospital and physician performance. Anthony Klotz, a management professor at London’s UCL School of Management, predicted in May 2021 that the Covid-19 pandemic would lead to pent-up resignations. “The pandemic brought the future of work into the present of work,” he said. Challenges faced include
burnout/ bullying/ stress/ workload/ lack of recognition / lack of respect/ lack of compensation for
education and experience/ the ‘Great Resignation’ with baby boomers retiring outpacing the new graduates/ and the fiscal crisis of healthcare. And the issues will likely get worse before better.Other authorsSee publication -
Why Surface Materials Matter in Health Care Settings
American Society for Microbiology
Health care facilities serve as havens for patients seeking treatment for disease and injury. However, they can also be home to a hidden world of microbes, lurking in places and devices that lead to life-threatening infections. According to the U.S. Centers for Disease Control and Prevention (CDC), 1 in 31 patients will acquire at least 1 health care-associated infection (HAI)—including infections with antibiotic-resistant organisms—while being treated for something unrelated.
For…Health care facilities serve as havens for patients seeking treatment for disease and injury. However, they can also be home to a hidden world of microbes, lurking in places and devices that lead to life-threatening infections. According to the U.S. Centers for Disease Control and Prevention (CDC), 1 in 31 patients will acquire at least 1 health care-associated infection (HAI)—including infections with antibiotic-resistant organisms—while being treated for something unrelated.
For centuries, it was believed that if everyone would do a better job cleaning, disinfecting and sterilizing when required, HAIs (and overall infections in the community setting) would be eliminated. However, data show this is not the case. Patients who occupy a room where a previous patient had an HAI have a 25% chance of acquiring the same infection, despite best efforts to follow required protocols for terminally cleaning and disinfecting the room. Furthermore, patients who have symptomatic infection may shed larger amounts of infectious microbes through body fluid and contaminate surrounding surfaces.
Surface type and building structure are, therefore, important components of the equation, which necessitate an organized effort to understand the root causes and develop multimodal solutions that support ongoing efforts to stop the spread of HAIs within health care facilities.Other authorsSee publication -

Rabies is an ancient, unpredictable and potentially fatal disease − two rabies researchers explain how to protect yourself.
The Conversation
A feral kitten in Omaha, Nebraska, tested positive for rabies in November 2023. It died of the raccoon variant of the virus, which is typically found only in the Appalachian Mountains. Detecting this variant hundreds of miles away in the Midwest raised concerns about a potential outbreak and launched a public health task force to vaccinate all raccoons in the area.

The History of Malaria
American Society of Microbiology, Bugs and Drugs
Malaria, an infectious disease caused by parasites belonging to the Plasmodium genus and transmitted by infected mosquitoes, is responsible for mortality and morbidity in over 40% of the world, making it one of the most devastating diseases in human history. In fact, the disease is thought to be responsible for between 2-5% of all fatalities that occurred during the 20th century (between 150 million-300 million deaths).

The Role of Bacterial Biofilms in Antimicrobial Resistance
American Society for Microbiology
Biofilms have long been recognized in nature and may be found adhering to a variety of surfaces, including rocks in streams (slime), mammalian teeth, roots of plants and even in water pipes. Biofilms may be the most adaptable microbial feature in nature. However, when the associated microbes are pathogenic, this ability to aggregate into biofilms becomes a significant virulence factor.

It provides critical data for physicians to diagnose and treat disease, dating back thousands of years. Unfortunately, laboratory medicine as a field is poorly understood by both the public and health care communities.
Laboratory medicine, also known as clinical pathology, is one of two main branches of pathology, or the study of the causes and effects of disease. Pathology covers many laboratory areas, such as blood banking and microbiology. Clinical pathology diagnoses a disease through laboratory analysis of body fluids such as blood, urine, feces and saliva. The other branch of pathology, anatomic pathology, diagnoses a disease by examining body tissues.
We are public health and medical laboratory scientists who specialize in microbiology and infectious diseases. There are a lot of steps between when your doctor orders a blood test to establishing a diagnosis. From the bedside to the lab bench, here’s how laboratory testing works.

At that time, some regions were already nearing levels typically observed during the virus’s seasonal peak months of December or January.
In other words, RSV has arrived early this year and is impacting hospitals, urgent care centers and clinics in numerous locations across the U.S. Knowing a bit about the disease, how to protect oneself and one's children—and when to seek treatment—are key to enduring this unwelcome seasonal guest.Other authorsSee publication -

On this episode we talk with Dr. Rodney Rohde, a Regents’ Professor at Texas State University, and the University Distinguished Chair and Professor for Clinical Laboratory Science (CLS). Dr. Rhode helps us to better understand what a Clinical Laboratory Scientist does, why they are so critical to healthcare delivery, and why it’s so important to raise awareness of the profession, as well as the risks we face due to the shortage. Dr. Rohde tells us that a big part of who he is today is because he is trying to put a face on this critical function that happens entirely in the background.
Dr. Rohde is not just an educator in academia. Throughout our conversation, and in everything he does, his goal is education. This is evident in each topic we discuss including:

Louis Pasteur’s scientific discoveries in the 19th century revolutionized medicine and continue to save the lives of millions today
The Conversation
Some of the greatest scientific discoveries haven’t resulted in Nobel Prizes.
Louis Pasteur, who lived from 1822 to 1895, is arguably the world’s best-known microbiologist. He is widely credited for the germ theory of disease and for inventing the process of pasteurization – which is named after him – to preserve foods. Remarkably, he also developed the rabies and anthrax vaccines and made major contributions to combating cholera.
But because he died in 1895, six years before the…Some of the greatest scientific discoveries haven’t resulted in Nobel Prizes.
Louis Pasteur, who lived from 1822 to 1895, is arguably the world’s best-known microbiologist. He is widely credited for the germ theory of disease and for inventing the process of pasteurization – which is named after him – to preserve foods. Remarkably, he also developed the rabies and anthrax vaccines and made major contributions to combating cholera.
But because he died in 1895, six years before the first Nobel Prize was awarded, that prize isn’t on his resume. Had he lived in the era of Nobel Prizes, he would undoubtedly have been deserving of one for his work. Nobel Prizes, which are awarded in various fields, including physiology and medicine, are not given posthumously.
During the current time of ongoing threats from emerging or reemerging infectious diseases, from COVID-19 and polio to monkeypox and rabies, it is awe-inspiring to look back on Pasteur’s legacy. His efforts fundamentally changed how people view infectious diseases and how to fight them via vaccines. -

Avian Influenza: Past, Present, and Future
American Society for Microbiology
Due to the possibility that bird flu viruses could mutate and gain the ability to spread easily between people, avian influenza poses a significant pandemic threat to birds and humans alike. The U.S. Centers for Disease Control and Prevention (CDC) has been monitoring for illness among humans exposed to infected birds since outbreaks were detected in poultry and wild bird populations in late 2021-2022. As of July 5, 2022, the U.S. Department of Agriculture (USDA) reported 40.09 M birds in 36…

The U.S. Centers for Disease Control and Prevention (CDC) has been monitoring for illness among humans exposed to infected birds since outbreaks were detected in poultry and wild bird populations in late 2021-2022. As of July 5, 2022, the U.S. Department of Agriculture (USDA) reported 40.09 M birds in 36 U.S. states to be infected with highly pathogenic avian influenza (HPAI). Out of the 382 flocks to test positive for the virus, 186 were commercial and 196 were backyard flocks. Yet, only 2 human cases associated with this particular group of avian influenza have been detected globally—1 in the U.S. and the other in the U.K. Understanding the history of this virus, as well as current guidelines and recommendations for investigations and response (i.e., monitoring for human infection and person-to-person spread) are extremely important for public health.

Yet, water can also be a place where dangerous and deadly microbes reside, waiting for a host to arrive.
Waterborne illnesses are likely to occur more frequently with the ongoing changes to our weather and climate patterns. The health effects of climate change could undercut public health advances and developments made in the last 50 years. Rain events, storm surges and the rise and fall of temperatures and humidity levels all impact the survival of microbes on land and in our seas. Some have evolved strategies to survive at temperatures higher than ambient body or host temperatures. -

Monkeypox isn’t a new disease. The first confirmed human case was in 1970, when the virus was isolated from a child suspected of having smallpox in the Democratic Republic of Congo (DRC). Monkeypox is unlikely to cause another pandemic, but with COVID-19 top of mind, fear of another major outbreak is understandable. Though rare and usually mild, monkeypox can still potentially cause severe illness. Health officials are concerned that more cases will arise with increased travel. -

Did you know that medical laboratory professionals provide roughly 13 billion laboratory tests each year? Laboratory testing is the single highest-volume medical activity affecting Americans, and it drives about two-thirds of all medical decisions made by doctors and other health care professionals from cradle to grave.1 Each one of us, in our own way, is an expert. Collectively, we are the heartbeat and brain of the health care and public health system. Yet, this expertise often stays buried in the laboratory. We must all find a way to take a bold step forward out of the shadow of the laboratory. We must step into the light where healthcare professionals, the public, and our patients see our expertise!
No one is born an expert. If you want to become a subject matter expert (SME), you have to start somewhere. An SME has a deep knowledge of a specific process, function, or technology (or a combination of all three). These experts are considered an authority on a certain topic—not only educated on the subject but has the capacity to share their knowledge with other interested parties. This information is important to your organization because it gives it a competitive edge. More importantly for us, an SME can provide visibility and awareness. -

I often refer to antimicrobial resistance as the slow-burning pandemic that continues to spread like a smoldering wildfire – picture a large expanding, ignored sustained bed of coals that continues to make global progress by sparking fires around the world. Antibiotic and antimicrobial resistance is everyone’s problem. The Centers for Disease Control and Prevention state that each year in the United States, at least 2.8 million people are infected with antibiotic-resistant microbes, and more than 35,000 die as a result.
The UN Ad hoc Interagency Coordinating Group on Antimicrobial Resistance report warns us that, without action, drug-resistant diseases could cause 10 million deaths each year by 2050. Furthermore, damage to the economy as catastrophic as the 2008-2009 global financial crisis can be expected. By 2030, antimicrobial resistance could force up to 24 million people into extreme poverty. At least 700,000 people die each year due to drug-resistant diseases, including 230,000 people who die from multidrug-resistant tuberculosis. More and more common diseases, including respiratory tract infections, sexually transmitted infections, and urinary tract infections, are untreatable; lifesaving medical procedures are becoming much riskier, and our food systems are increasingly precarious.
How can we help? What can those of us who work in public health and healthcare do to help curb this global emergency? The following commentary will discuss recent research and insight regarding how laboratories can play a critical role in reducing antimicrobial resistance.

It may be summer before children under 16 can be vaccinated against COVID-19 in the United States. That’s a problem for reaching herd immunity quickly.
Children are a significant portion of the population – roughly 65 million are under the age of 16, making up 20% of people in the U.S. While children appear to face less danger of severe illness or death, they can still spread the virus, though how much young children contribute to transmission is still unclear.

For anyone of us involved in medical laboratory or public health laboratory testing, we understand the critical importance of clinical quality control (QC). With the ongoing fallout from the massive contamination of laboratory test kit reagents at the Centers for Disease Control and Prevention (CDC), this issue has been front and center not only in the laboratory community but in the public mindset as well. How could the preeminent public health laboratory for the United States fail in such a critical moment – a global pandemic? We do not have to look only to the CDC; there are other examples of failed testing across the world. Typically, one thinks of direct patient care when we hear or read about medical errors costing lives. In this article, we will examine the issues surrounding QC and other measures to ensure not only the accuracy of a laboratory test, but the very health and life of the citizens these tests should be protecting. -

Some Truths About#SARSCoV2 / #COVID19 / #coronavirus.
Invited article for Medical Laboratory Professionals’ Association of Ontario (MLPAO), Spring 2020 ADVOCATE 27(1):5-6.
As we continue to watch in real time the coronavirus outbreak, there is another virus
spreading perhaps at an even faster and more dangerous pace – the virus of misinformation. The sensational nature of an infectious disease outbreak combined with the ease of spreading information leads to rumors and misinformation, and this has certainly been true with the 2019 novel coronavirus (SARSCoV2). -
Uncovering the Novel Coronavirus. Invited Monthly Columnist for “Under the Microscope”
Healthcare Hygiene Magazine. March 2020, Volume 2, Issue 3
Novel outbreaks from any microbe should always be of public health concern. The risk from these outbreaks depends on characteristics of the virus, including whether and how well it spreads between people, the severity of resulting illness, and the medical or other measures available to control the impact of the virus (e.g., vaccine or antivirals).

Outbreaks of new (novel) virus infections among people are always public health concerns. Public health officials, scientists, researchers, media and the public should take this current 2019-nCoV outbreak seriously and monitor it closely. According to the Centers for Disease Control and Prevention (CDC), the risk to individuals is dependent on exposure. To date, some people will have an increased risk of infection, for example healthcare workers caring for 2019-nCoV patients and other close contacts, as well as immunocompromised individuals. For the general American public, who are unlikely to be exposed to this virus, the immediate health risk from 2019-nCoV is considered low at this time. -

The Influenza Hospitalization Network (IHSN or FluSurv-NET) was evaluated using the Centers for Disease Control and Prevention's (CDC) guidelines for evaluating a public health surveillance system. The IHSN was evaluated for usefulness, simplicity, flexibility, data quality, acceptability, sensitivity, predictive value positive, representativeness, timeliness, and stability. The IHSN was found to utilize a broad range of sources for influenza surveillance which can be openly accessed via the CDC's "FluView" online application. The IHSN is highly adaptable with its capacity to accommodate additional data sources when needed. The over-inclusiveness of different laboratory diagnostic methodologies was found to be detrimental to the overall data quality of the IHSN in the form of variable sensitivity and positive predictive value measures amongst the CDC's acceptable testing methods. Overall, the IHSN is a very robust system that allows for timely access to influenza data by public health officials. However, the inclusivity of the IHSN causes it to fall short when considering the importance of consistency in data collection practices. The IHSN fails to take into account several factors that could either artificially increase, or decrease case counts. We recommend the IHSN integrate a more streamlined and reliable data collection process and standardize its expectations with all of its reporting sites.

What most people do not understand about the environment is that there is an entire world of unseen microbes hiding on all surfaces. Bacteria, viruses, fungi and other microbial life can exist, at least for some time, on almost any surface known to humankind. Likewise, many of us do not realize that “clean does not necessarily mean microbial clean.” In other words, the cleaning and disinfection of surfaces has complex scientific nuances. One must understand the type of surface with respect to the proper choice of disinfectant. In the fight against infections, material compatibility is critically important. The healthcare environment uses any number of materials (e.g. plastics, vinyl, metals, etc.) for equipment, surfaces, and devices that are regularly cleaned with disinfectants. Harsh disinfectants may cause equipment damage, unnecessary costs, and contribute to poor clinical outcomes. We must work to develop standards, resources, and education to overcome key challenges in surface cleaning and disinfection. Our call to action must be a new paradigm on the upstream challenges (design and choice of surfaces) as well as the downstream options (cleaning and disinfection of surfaces) for overall patient safety and health.

Antimicrobial resistance (AMR) is a complex issue that has currently reached a dangerous tipping point. The nature of this critical public health and healthcare problem has two primary components: 1) the emergence of diverse AMR pathogens, and 2) the alarming rapid spread of these AMR pathogens in a wide array of geographic and densely populated regions.

Antimicrobial resistance (AMR) is a complex issue that has currently reached a dangerous tipping point. The nature of this critical public health and healthcare problem has two primary components: 1) the emergence of diverse AMR pathogens, and 2) the alarming rapid spread of these AMR pathogens in a wide array of geographic and densely populated regions. The adaptation and survival of these dangerous pathogens is associated with ongoing and increasing natural selective pressure as it relates to human, animal, and environmental health settings. The primary drivers for this mounting trend of AMRs include, but not limited to, changing patterns of pathogen epidemiology, emergence of drug-resistance genes, animal husbandry, antimicrobial use / stewardship, population mobility, increased rates of human urbanization, and the movement and ease of products and goods across global settings. Simply stated, AMR pathogens are incredibly versatile biological entities at adaptation to every natural (and unnatural) niche known and make themselves at home regardless of where they land. Understanding AMRs is critical to curbing their ongoing global drift. For this special article, we will address the emergence and spread of AMR pathogens from a medical laboratory and public health lens, and how this new threat affects the ever-evolving relationship between hosts and pathogens.

Castro-Arellano*, G. Suzán, G.E. Garcia-Peña, T.E. Lee Jr., R.E. Rohde, et al. EcoHealth (2018): pp. 1-46.
Rodents represent 42% of the world’s mammalian biodiversity encompassing 2,277 species populating every continent (except Antarctica) and are reservoir hosts for a wide diversity of disease agents. Thus, knowing the identity, diversity, host–pathogen relationships, and geographic distribution of rodent-borne zoonotic pathogens, is essential for predicting and mitigating zoonotic disease outbreaks. Hantaviruses are hosted by numerous rodent reservoirs. However, the diversity of rodents harboring hantaviruses is likely unknown because research is biased toward specific reservoir hosts and viruses. An up-to-date, systematic review covering all known rodent hosts is lacking. Herein, we document gaps in our knowledge of the diversity and distribution of rodent species that host hantaviruses. Of the currently recognized 681 cricetid, 730 murid, 61 nesomyid, and 278 sciurid species, we determined that 11.3, 2.1, 1.6, and 1.1%, respectively, have known associations with hantaviruses. The diversity of hantaviruses hosted by rodents and their distribution among host species supports a reassessment of the paradigm that each virus is associated with a single-host species. We examine these host–virus associations on a global taxonomic and geographical scale with emphasis on the rodent host diversity and distribution. Previous reviews have been centered on the viruses and not the mammalian hosts. Thus, we provide a perspective not previously addressed. -

Seasonal flu is a serious, highly contagious respiratory illness caused by the influenza virus. In the United States, approximately five to 20 percent of individuals get the flu each year; more than 200,000 are hospitalized, and tens of thousands die from flu-related complications.1 So why do people not vaccinate against flu or for that matter other infectious diseases? In my personal and professional experience, I believe it has to do with a breakdown in health literacy and science communication. Individuals have varying levels of awareness/attitudes toward the flu vaccine, side effects, and overall effectiveness.2 Importantly, many people usually report misconceptions about the side effects of the flu vaccine, which can perpetuate fear and create vaccine avoidance. Unfortunately, on more accounts than I care to say, my colleagues, students, friends, and others report a reluctance to be vaccinated due to concerns that the vaccine would either cause illness or be ineffective at preventing flu. This commentary / editorial will attempt to explain in common terms what really happens when one gets the flu (and other) vaccines.3

Pneumonia and surgical-site infection are the most common infection types, with Clostridium difficile as the most common pathogen. The World Health Organization has stated that by 2050, antibiotic resistance and HAIs will have a global economic impact of up to 100 trillion USD and 10 million deaths. If this prediction comes true, that will be one new antibiotic resistant infection every three seconds and it will exceed cancer mortality. Antibiotic resistance infections already kill more than HIV and H1N1 influenza combined. Infection control and antimicrobial stewardship are identified as two key measures that can address this global problem. This commentary will discuss how the pharmacy and the medical laboratory professional may be considered the Super Stewards of antibiotic stewardship.

Current methods for addressing catheter-associated urinary tract infections (CAUTIs) are mostly focused on the biological causes, emphasizing the adherence to prevention guidelines, collecting data and disseminating the results, as well as identifying emerging threats from infectious organisms. However, there is a need for tools that can help organizations to implement interventions in ways that maximize the benefits while minimizing the impact upon efficient operations. This research extends the current methods for addressing CAUTIs to a new level beyond the current state of practice by introducing a new discrete-event simulation model for system assessment and determination of the clinical efficacy of CAUTI preventive interventions. The simulation model provides a platform where proposed clinical interventions can be studied and analyzed, giving an idea on possible expectations before clinical research is conducted, saving time, money and minimizing risks. The computational results provide useful insights into patient service management for CAUTI prevention and show that operational factors such as the nurse:bed ratio, catheter daily removal chance, and late maintenance risk have a significant impact in the intensive care unit (ICU) CAUTI rate.

All warm-blooded animals can contract rabies, particularly mammals. A viral disease of the central nervous system, rabies is spread between animals, including humans, when saliva containing the virus enters an opening in the skin. This is typically achieved through the bite of a rabid animal, but transmission can also occur when infected saliva enters through mucous membranes or a break in the skin.

A little over two years ago, I wrote an article for Elsevier Connect entitled “The Hidden Profession that Saves Lives.” The article details my journey as a microbiologist and molecular epidemiologist who discovered the sometimes unknown profession of a medical laboratorian. I was overwhelmed with the viral response (over 250,000 views!) that the article generated, not only with my colleagues, but with the general public who typically do not see us as first line responders in their healthcare experience. I tried to encapsulate the very essence of what our profession is by discussing how one can become a medical laboratorian and exactly what it is that we do in our job and career. The article discusses the different routes to become a medical laboratory technician (MLT), a medical laboratory scientist (MLS) and/or a specialist in a particular area (e.g. SM is a specialist in microbiology). I encourage you to revisit the article and share it with your friends, family, colleagues, and social networks to assist us and empower our profession to become transparent to everyone.

Riggs JM, McLean RJC, Rohde RE, Aron GM (2016) Development of Teicoplanin Tolerance by Staphylococcus epidermidis and Increased Susceptibility to Bacteriophage Type 92 by Methicillin-Resistant Staphylococcus aureus in Polymicrobial Biofilms.
J Infect Dis Epidemiol 2:009
Staphylococcus epidermidis is a commensal commonly found in polymicrobial biofilms with
Staphylococcus aureus. Given the increasing drug resistance in Staphylococci, we explored
combination therapy with teicoplanin and bacteriophage type 92 (Siphoviridae) on the survival and antibiotic tolerance of methicillin-resistant S. aureus (MRSA) and S. epidermidis to teicoplanin
and bacteriophage in 48-h pure and mixed culture biofilms. The combination of teicoplanin and…Staphylococcus epidermidis is a commensal commonly found in polymicrobial biofilms with
Staphylococcus aureus. Given the increasing drug resistance in Staphylococci, we explored
combination therapy with teicoplanin and bacteriophage type 92 (Siphoviridae) on the survival and antibiotic tolerance of methicillin-resistant S. aureus (MRSA) and S. epidermidis to teicoplanin
and bacteriophage in 48-h pure and mixed culture biofilms. The combination of teicoplanin and bacteriophage was more effective against MRSA, but not S. epidermidis monocultures, than the use of either teicoplanin or phage alone. In polymicrobial biofilms, however, MRSA acquired increased susceptibility to phage infection and S. epidermidis acquired increased tolerance to teicoplanin, as well as increased fitness. The results demonstrate bacteriophage alone was more effective against MRSA and S. epidermidis in polymicrobial biofilms compared to the combination of bacteriophage and teicoplanin.Other authorsSee publication -

Currently, a “new” (not really) arbovirus known as Zika has made the headlines in the U.S. On January 11, 2016, Texas health officials confirmed the latest case of imported Zika in one patient who recently traveled to Latin America and subsequently exhibited characteristic symptoms including fever, rash and joint pain. Areas of Texas, like in some other states in the southern U.S., are home to two species of Aedes mosquitoes capable of transmitting Zika; however, there are no known cases of local transmission of the disease so far in the U.S. mainland. Zika follows a long history of other mosquito transmitted viruses, like dengue, West Nile virus, and chikungunya.

Background: More people in the US now die from Methicillin-Resistant Staphylococcus aureus (MRSA) infections than from HIV/AIDS. Often acquired in healthcare facilities or during healthcare procedures, the extremely high incidence of MRSA infections and the dangerously low levels of literacy regarding antibiotic resistance in the general public are on a collision course. Traditional medical approaches to infection control and the conventional attitude healthcare practitioners adopt toward public education are no longer adequate to avoid this collision. I conducted a study with MRSA survivors using constructivist theory, semi-structured face-to-face and phone interviews which allowed participants to tell their stories so their experiences could deepen our understanding of this crucial health issue.
Significance: This study underscores the critical importance of educational programs for patients, and improved continuing education for healthcare providers. Five specific results of this study can reduce the vacuum that currently exists between the knowledge and information available to healthcare professionals, and how that information is conveyed to the public. These points include: 1) a common model of MRSA patients’ learning and adaptation; 2) the self-directed nature of adult learning; 3) the focus on general MRSA information, care and prevention, and antibiotic resistance; 4) the interconnected nature of adaptation; and, 5) the need for a consistent step by step plan to deal with MRSA provided at the time of diagnosis. -

S. aureus isolates were plated to HardyCHROM agar to identify MRSA. VITEK antibiotic susceptibility testing confirmed MRSA isolates.
Results:
Forty-seven samples showed growth (47/88, 53%), and 7 tested positive for S. aureus (7/47, 15%). Of those 7, one demonstrated oxacillin resistance and was confirmed as MRSA (1/7, 2%). Remaining samples grew other species of Staphylococcus and gram-negative bacilli.
Discussion:
Given high classroom utilization, staphylococci environmental prevalence would be expected. However, the presence of MRSA was unexpected. Results demonstrate the potential for easily transmissible and potentially harmful organisms to be present in multi-use classrooms utilized by health professions students where frequent skin-to-skin contact occurs. Strict, routine cleaning of plinths and other equipment is imperative in reducing exposure risk.

8 things you may not know about rabies - but should!
Elsevier Connect
Rabies is a viral zoonosis affecting the central nervous system of warm-blooded animals. Transmission occurs when saliva containing the rabies virus is introduced into an opening in the skin, usually via the bite of a rabid animal. Though rare, transmission could occur through infected saliva contacting mucous membranes or a scratch or other break in the skin. Despite its severity, there is still much the public and even health professionals may not know about rabies.

Effect of Bacteriphage Infection in Combination with Tobramycin on the Emergence of Resistance in Escherichia coli and Pseudomonas aeruginosa Biofilms
MDPI Viruses
Bacteriophage infection and antibiotics used individually to reduce biofilm mass often result in the emergence of significant levels of phage and antibiotic resistant cells. In contrast, combination therapy in Escherichia coli biofilms employing T4 phage and tobramycin resulted in greater than 99% and 39% reduction in antibiotic and phage resistant cells, respectively. In P. aeruginosa biofilms, combination therapy resulted in a 60% and 99% reduction in antibiotic and PB-1 phage resistant…

In contrast, combination therapy in Escherichia coli biofilms employing T4 phage and tobramycin resulted in greater than 99% and 39% reduction in antibiotic and phage resistant cells, respectively. In P. aeruginosa biofilms, combination therapy resulted in a 60% and 99% reduction in antibiotic and PB-1 phage resistant cells, respectively. Although the combined treatment resulted in greater reduction of E. coli CFUs compared to the use of antibiotic alone, infection of P. aeruginosa biofilms with PB-1 in the presence of tobramycin was only as effective in the reduction of CFUs as the use of antibiotic alone. The study demonstrated phage infection in combination with tobramycin can significantly reduce the emergence of antibiotic and phage resistant cells in both E. coli and P. aeruginosa biofilms, however, a reduction in biomass was dependent on the phage-host system.

A Secret Weapon for Preventing HAIs: A scientist’s message to hospitals trying to rid themselves of healthcare-associated infections
Elsevier Connect, July 15, 2014

Healthcare associated infections (HAIs),in the past decade, are responsible for about 4.5 HAIs for every 100 hospital admissions in the US, with the overall cost to hospitals ranging from $35.7 billion to $45 billion. Worldwide, the incidence is about 10.1 percent. Embedded and woven among this troubling global epidemic is the perfect storm of not using a multimodal approach in the war against HAIs. A major weapon in that war is the enlightened hospital in which environmental services is no longer considered among healthcare's lowliest of activities, carried out by a group of virtually invisible staff members who are at the bottom of the hospital totem poll. Rather, they are first-line-of-defense specialists whose training has included learning best practices for effective infection prevention, on-going in-service education and effective hygiene management in patient rooms and all other areas of the hospital.

DESIGN: A prospective longitudinal cohort design with six times of measurement. Data collected August 2010 to May 2012. IRB (2010F5693)
MAIN OUTCOME MEASURES: Screening for Staphylococcus aureus and MRSA identification;
confirmation and antibiotic susceptibility by Vitek 2; self-administered questionnaires delineating
demographics and risk factors; panel logistic regression models by Stata version 13
RESULTS: MRSA colonization did not increase. S. aureus incidence was 17.7 – 26.4%. Staphylococcal species incidence other than S. aureus increased (9.2 – 82.3%). The following odds ratio (OR) associations were found to be statistically significant: boil or skin infections with S. aureus (OR = 2.94, p < .01), working or volunteering in a healthcare facility odds with species
other than S. aureus (OR = 4.41, p < .01) and gym and sports facilities odds with S. other (OR 2.45, p < .01). The most frequently occurring species at Wave 5 was S. hominis (21 isolates) while the most frequently occurring species at Wave 6 was S. epidermidis (25 isolates).
CONCLUSIONS: MRSA colonization did not increase during longitudinal study. S. aureus colonization remained fairly stable throughout the study (17 – 26%). Species colonization with non S. aureus species (e.g. S. hominis, S. epidermis, S. haemolyticus) increased significantly (9.2 – 82.3%) during clinical rotations. Knowledge of infection control and compliance may have contributed to an absence of MRSA colonization; however, the colonization by other staphylococci has been shown to be a risk factor for MRSA acquisition.Other authorsSee publication -

Design—Epidemiological study.
Sample—Laboratory reports of bats that had been submitted for rabies testing in Texas
from 2001 through 2010.
Procedures—Laboratory reports were reviewed to obtain information on seasonality of
rabies in bats; distribution, species, and rabies virus variants of rabid bats; and human and
domestic animal exposures to rabid bats.
Results—The number of rabid bats during the first 5 years of the study period remained
static until a > 2-fold increase in 2006; during the subsequent 4 years, the annual number
of rabid bats remained at this higher level, including a peak in 2008. The highest proportions
of rabid bats were seen in late summer and early fall. The Brazilian free-tailed bat (Tadarida
brasiliensis) was the most often affected species. Additionally, the rabies virus variant associated
with the Brazilian free-tailed bat was the most prevalent. The percentage of rabid
bats from urban areas was greater than that from rural areas. Dogs and cats were the domestic
animals most frequently exposed to rabid bats. Most humans exposed to rabid bats
did not report a known bite or scratch. The highest numbers of humans exposed to rabid
bats were males between 11 to 15 years old.
Conclusions and Clinical Relevance—Information on the epidemiology of rabies in bats
and the epidemiology of exposures to rabid bats may be useful in planning and implementing
local, state, and national rabies control and prevention campaigns and in encouraging
rabies vaccination of domestic animals. (J Am Vet Med Assoc 2013;243:1129–1137)Other authors -

Abstract. Objective and Participants: In summer 2011, the investigators examined the prevalence of MRSA, Staphylococcus aureus, and other staphylococci found on exercise equipment in a higher education athletic facility. Methods: One hundred twenty-five samples were collected from various exercise equipment and areas within the facility. Samples were screened for staphylococci using standard microbiological techniques. Confirmation of S. aureus was conducted by DRYSPOT Staphytect Plus™. MRSA isolates were confirmed with CHROMagarTM; VITEK® 2 antibiotic susceptibility testing and PFGE characterized all MRSA isolates. Results: Prevalence of MRSA was 6%, S. aureus 38%, other staphylococci 52% and negative or no growth 4%. Prevalence of S. aureus and MRSA was highest on free weights and mats, respectively. PFGE characterized all MRSA isolates as HA-MRSA (USA100). Conclusions: Potential exposure risks from staphylococci exist in college athletic facilities. Compliance (disinfection) and creative health education may reduce the transmission of pathogens, environmental load, and incidence of colonization or infection in college students.

Molecular Diagnosis and Epidemiology of Rabies
Modern Clinical Molecular Techniques (New Edition), NY: Springer Press, 2012
Rabies virus diagnostic and typing methods differ among which virus populations can be detected and segregated. Lyssavirus genera may differ so greatly that serological testing alone may be sufficient to differentiate between them. Unique monoclonal antibody patterns among rabies viruses have also been used effectively for many of the terrestrial animal reservoirs for rabies in the U.S. However, genetic typing, especially nucleotide sequence analysis, allows the most precise method to…

There is currently available, without a physician’s order, an array of laboratory tests that appears to have no diagnostic value whatsoever. The procedures are advertised as being helpful in the diagnosis of very serious diseases and states of malnutrition. A careful review of the methods of testing, the principles, interpretation of the test results, and the credentials of the individuals performing these tests is revealing. Much of this testing is performed and interpreted by alternative medicine practitioners with little or no background in science. Their “doctorate” degrees are often granted through a correspondence alternative medicine course or a short course that requires actual attendance. Medical Laboratory Technicians and Medical Technologists have worked very hard through accredited educational programs to acquire the knowledge and skill that allows them to competently practice their profession. Given their educational background, it seems very unlikely that alternative medicine practitioners are qualified to perform any moderately complex or highly complex laboratory test. A review of the dubious advertising claims for some of these tests supports this idea.

The primary goals of this project was to develop a valid and reliable instrument to measure the self-efficacy of undergraduate chemistry students (ChemSE) and to determine the relationship between ChemSE and an established measure of generalized self-efficacy (GSE). Two hundred and fifty undergraduate students were solicited with 57 respondents of variable demographics. The results indicated the instrument was reliable at measuring general self-efficacy (GSE) and chemistry self-efficacy (CSE) at α = 0.881 and α = 0.821 respectively. In a second study, 101 undergraduate chemistry students responded to the survey at the beginning of their semester. The data from this study indicated a significant relationship (t = 5.36, p<.001) between GSE and ChemSE with medium effect size (R2 = .24). In this study, ethnicity and gender were not significantly related to GSE or ChemSE.

The shortage of clinical laboratory scientists (CLS) has been well-documented in the healthcare environment. This growing concern only becomes more critical as we enter the retiring baby boomer era in our society. Concomitantly, the problem of addressing how university CLS programs recruit and retain faculty to teach and satisfy research agendas is not being studied. These two problems, if allowed to collide, will provide a “perfect storm” with serious implications for an ongoing shortage of personnel and overall quality for the profession. CLS faculty, in the university setting, must typically satisfy the three tenets for tenure and promotion – teaching, scholarship, and service. While teaching and service will always be critical, scholarship (research) is an area of expertise that must be “taught” and mentored for future CLS faculty to be successful in the very real arena of “publish or perish.” This article provides a commentary with specific details associated with our experience in offering an evolving dedicated CLS clinical research course to purposively “grow our own” students in the art of conducting successful research. It offers a flexible template for adapting or incorporating a lecture and laboratory course to address theoretical and practical knowledge in the realm of clinical research. Additionally, a discussion of other research mentoring activities in our program will be outlined. The long term goal (and hope) of these program objectives is to build a culture of research for current faculty and for CLS graduates. This paper provides an approach to embedding these research ideals in all CLS graduates and, importantly, an intentional attempt to create a mindset for a possible career as a future CLS faculty member who can be successful in both the university and clinical environment.

More people in the US now die from Methicillin Resistant Staphylococcus aureus (MRSA) infections than from HIV/AIDS. Often acquired in healthcare facilities or during healthcare procedures, the extremely high incidence of MRSA infections and the dangerously low levels of literacy regarding antibiotic resistance in the general public are on a collision course. Traditional medical approaches to infection control and the conventional attitude healthcare practitioners adopt toward public education are no longer adequate to avoid this collision. This study helps us understand how people acquire and process new information and then adapt behaviours based on learning. This study underscores the critical importance of educational programs for patients, and improved continuing education for healthcare providers. Five specific results of this study can reduce the vacuum that currently exists between the knowledge and information available to healthcare professionals, and how that information is conveyed to the public. These points include: 1) a common model of MRSA learning and adaptation; 2) the self-directed nature of adult learning; 3) the focus on general MRSA information, care and prevention, and antibiotic resistance; 4) the interconnected nature of adaptation; and, 5) the need for a consistent step by step plan to deal with MRSA provided at the time of diagnosis.

Design—Epidemiologic study.
Sample Population—Reports of skunks that had been submitted for rabies testing in
Texas from 1953 through 2007.
Procedures—Reports were reviewed to obtain information on seasonality of rabies in skunks,
seasonality of human and domestic animal exposure to rabid skunks, commonly reported clinical signs
of rabies in skunks, domestic animals frequently exposed to rabid skunks, common routes of exposure
of domestic animals to rabid skunks, disposition of domestic animals exposed to rabid skunks, age
and gender of humans exposed to rabid skunks, and usual routes of exposure of humans to rabid
skunks.
Results—On a yearly basis, the number of rabid skunks peaked in 1961, 1979, and 2001. On a monthly
basis, the number of rabid skunks peaked in March and April. Over the study period, the percentage
of rabid skunks from urban areas increased and the percentage from rural areas decreased. Striped
skunks were the most common species. Dogs and cats were the domestic animals most frequently
exposed to rabid skunks. On average, the highest numbers of humans exposed to rabid skunks were
between 36 and 50 years old. Most humans were exposed through means other than a bite. Typical
behaviors of rabid skunks were entering a dog pen, appearing outside during daytime, and attacking
pets.
Conclusions and Clinical Relevance—Information on the epidemiology of rabies in skunks may be
useful in planning and implementing local, state, and national rabies control and
prevention campaigns. (J Am Vet Med Assoc 2009;234:xxx–xxx)

Background: HPS is a rare cardiopulmonary disease caused by strains of the Hantavirus. Human infections occur by inhalation of aerosolized infectious particles from excreta of infected rodents. HPS was first discovered after a 1993 epidemic in the southwestern United States. This study provides a descriptive analysis of all the Texas cases reported to the Texas Department of State Health Services (TDSHS) for which data are available. Results: 32 cases of HPS were reported to the TDSHS from 1993 through 2006. Of the 32 cases, 26 were due to Sin Nombre Virus (SNV) and 4 were due to Bayou virus. Mortality was 37.5% overall (42% for SNV and 0% for Bayou).All cases were admitted to the hospital. The incidence of clinical characteristics of HPS cases were as follows: Fever ≥101°F (83%), nausea and/or vomiting (94%), diarrhea (67%), syncope and/or confusion (67%), headache (86%), hematocrit ≥55% (30%), platelets ≤100,000 (93%), creatinine ≥1.5 (60%), leukocyte count ≥10,000(81%) and ≥20,000 (48%), bands ≥10 (85%), oxygen saturation ≤90% (100%), presence of immunodeficiency disease (3%). Compared to the population (pop) in Texas, males and those aged 20-64 years were overrepresented (63% of cases vs. 49% of pop, and 84% of cases vs. 54% of pop respectively). West Texas and coastal regions were also overrepresented. 85% of HPS cases reported seeing rodents or rodent excreta in or around their home. 85% of HPS cases were initially seen by a physician and dismissed to home, later to be admitted to the hospital. Conclusions: HPS is a rare but serious illness that may be misdiagnosed. Middle aged males are more commonly affected. The distribution of HPS is mainly along the coast and in west Texas. Common laboratory features include thrombocytopenia, bandemia, and hematocrit ≥55. Respiratory symptoms are often accompanied by gastrointestinal symptoms. Most cases were associated with seeing rodents or rodent excreta at home.

Methicillin Resistant Staphylococcus aureus: Nasal Carriage Rate and Characterization in a Texas University Setting
Clinical Laboratory Science, 22(3): 176-184.
Of the 203 participants who were screened, 60 (29.6%) carried S. aureus. Univariate analysis found that only hospitalization in the past 12 months was significantly associated with the risk of being a S. aureus carrier (OR=3.0, 95% CI 1.28-7.03). Of the 60 participants that carried S. aureus, 15 were identified as MRSA. This relates to a 7.4% MRSA carriage rate among generally healthy university students.

Univariate analysis found that hospitalization in the past 12 months (OR = 4.2, 95% CI 1.29-13.36) and recent skin infection (OR = 4.4, 95% CI 1.07-18.24) were significantly associated with the risk of being a MRSA carrier. No unique antibiotic susceptibility patterns were identified with the MRSA isolates. The carriage rate of S. aureus is consistent with similar studies. MRSA carriage in this university study appears high as compared to the general population. Although this study did not confirm a variety of risk factors for carriage of MRSA previously identified by others, university healthcare personnel should be aware of the changing epidemiology of MRSA and preventive measures needed to avoid outbreaks.

Methicillin Resistant Staphylococcus aureus Nasal Carriage Rate in Texas County Jail Inmates
Journal of Correctional Health Care, 2007;13(4): 289-295
Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a health issue in corrections. The Texas Department of State Health Services (DSHS) partnered with an urban jail to investigate risk factors for MRSA carriage. This study assessed nasal carriage rate and strainrelatedness of MRSA among recently booked inmates. Of 403 inmates, 115 (28.5%) carried S. aureus; 18 were MRSA-positive (4.5%). Pulsed field gel electrophoresis identified 10 MRSA

The Texas Department of State Health Services (DSHS) partnered with an urban jail to investigate risk factors for MRSA carriage. This study assessed nasal carriage rate and strainrelatedness of MRSA among recently booked inmates. Of 403 inmates, 115 (28.5%) carried S. aureus; 18 were MRSA-positive (4.5%). Pulsed field gel electrophoresis identified 10 MRSA
strains. Previous health care exposures and history of skin infection were more strongly associated with carriage risk than previous correctional facility exposure, although none of these exposures was statistically significant after adjustment. Our data suggest that MRSA is endemic in persons coming into correctional facilities. Correctional health care workers should be prepared to treat MRSA infections that arise from exposures before incarceration.Other authorsSee publication -

Bat-associated rabies virus in skunks
Emerg Infect Dis
Rabies was undetected in terrestrial wildlife of northern Arizona until 2001, when rabies was diagnosed in 19 rabid skunks in Flagstaff. Laboratory analyses showed causative rabies viruses associated with bats, which indicated cross-species transmission of unprecedented magnitude. Public health infrastructure must be maintained to address emerging zoonotic diseases.

Typing of rabies virus isolates by DNA enzyme immunoassay
J Clin Virol. 12: 9-19
Background: Alternatives to antigenic typing are needed for epidemiologic surveys of the rabies virus associated with translocated coyotes and foxes, especially in areas where a closely related rabies virus is transmitted by striped skunks.

Objective: We developed and evaluated two enzyme based typing methods for rabies virus. The products of a reverse transcription-polymerase chain reaction (RT/PCR) or the nucleoprotein gene were hybridized to type specific probes and detected by enzyme assay after immobilization on microtiter plates.
Study design: We tested RT/PCR products of 27 rabies isolates by two different DNA enzyme immunoassays (DEIA) and evaluated the quality of the results from the corresponding nucleotide sequence or the samples.
Results: Using a set of two probes, one of the DEIAs correctly identified 26/27 samples as variants of rabies virus associated with either skunks, foxes, or coyotes. The identity of one fox rabies sample was unresolved by this assay. The second DEIA correctly identified 24/27 samples as variants of rabies virus associated with either skunks, foxes, or coyotes. This assay did not resolve the identity of two fox rabies samples, and misidentified one fox rabies sample as a skunk rabies sample.
Conclusions: DEIA can be used for epidemiologic studies or variants of rabies virus associated with skunks, foxes, and coyotes. Both DEIA methods were effective when typing probes recognized changes at a minimum or two nucleotide positions between variants, but only one assay method was sufficiently stringent to detect a single base pair mismatch. The inherent mutability of RNA viruses must be considered when designing and evaluating typing methods.

Viral RNA synthesis, total protein synthesis and the synthesis of specific poliovirus proteins were determined in the presence of synergistic (low) and antagonistic (high) combinations of PAP and guanidine. Viral proteins 3AB and 3C were blocked in the presence of either guanidine or PAP at low concentration. In the presence of the synergistic drug combination, proteins 2C, 2A and 3A, in addition to proteins 3AB and 3C failed to appear. Also, proteins 3D, VPO and VP3 were present in reduced amount. The mechanism of action of the synergistic drug combination may involve an inhibition in the processing of poliovirus polyprotein P1 which is the precursor protein for essential capsid endproducts VPO and VP3.
Viral RNA synthesis was stimulated in the presence of either PAP or guanidine alone at low concentration and in the presence of the synergistic drug combination. This may be due to the absence of protein VPg (3B) which has a regulatory function on RNA synthesis. In contrast, viral RNA synthesis was inhibited almost completely in the presence of either PAP or guanidine at high concentration and in the presence of the antagon~sticd rug combination. The antagonistic drug combination resulted in the failure to synthesize plus-strand RNA from the parental RF-RNA which led to a complete absence of viral protein synthesis.

Did you know that medical laboratory professionals provide roughly 13 billion laboratory tests each year? Laboratory testing is the single highest-volume medical activity affecting Americans, and it drives about two-thirds of all medical decisions made by doctors and other health care professionals from cradle to grave.1 Each one of us, in our own way, is an expert. Collectively, we are the heartbeat and brain of the health care and public health system. Yet, this expertise often stays buried…
Did you know that medical laboratory professionals provide roughly 13 billion laboratory tests each year? Laboratory testing is the single highest-volume medical activity affecting Americans, and it drives about two-thirds of all medical decisions made by doctors and other health care professionals from cradle to grave.1 Each one of us, in our own way, is an expert. Collectively, we are the heartbeat and brain of the health care and public health system. Yet, this expertise often stays buried in the laboratory. We must all find a way to take a bold step forward out of the shadow of the laboratory. We must step into the light where healthcare professionals, the public, and our patients see our expertise!
No one is born an expert. If you want to become a subject matter expert (SME), you have to start somewhere. An SME has a deep knowledge of a specific process, function, or technology (or a combination of all three). These experts are considered an authority on a certain topic—not only educated on the subject but has the capacity to share their knowledge with other interested parties. This information is important to your organization because it gives it a competitive edge. More importantly for us, an SME can provide visibility and awareness.
