Virulence
Virulence is, by MeSH definition, the degree of pathogenicity within a group or species of parasites as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. The pathogenicity of an organism - its ability to cause disease - is determined by its virulence factors. The noun virulence derives from the adjective virulent. Virulent can describe either disease severity or a pathogen's infectivity. The word virulent derives from the Latin word virulentus, meaning "a poisoned wound" or "full of poison."
In an ecological context, virulence can be defined as the host's parasite-induced loss of fitness. Virulence can be understood in terms of proximate causes—those specific traits of the pathogen that help make the host ill—and ultimate causes—the evolutionary pressures that lead to virulent traits occurring in a pathogen strain.
Virulent bacteria
The ability of bacteria to cause disease is described in terms of the number of infecting bacteria, the route of entry into the body, the effects of host defense mechanisms, and intrinsic characteristics of the bacteria called virulence factors. Many virulence factors are so-called effector proteins that are injected into the host cells by special secretion machines such as the type 3 secretion system. Host-mediated pathogenesis is often important because the host can respond aggressively to infection with the result that host defense mechanisms do damage to host tissues while the infection is being countered.
Virulence (journal)
Virulence is a peer reviewed medical journal that covers microbiology and immunology specifically, microorganism pathogenicity, the infection process and host–pathogen interactions. It is published 8 times per year by Taylor & Francis. It was previously published 6 times per year by Landes Bioscience. The journal was established in 2010 by Eva M. Riedmann, and Eleftherios Mylonakis. The editor-in-chief is Eleftherios Mylonakis.

Your Own Palestine
by: Virulencepicture
from world power to servant state
from self-sufficient to tied and raped
civilizations clashed one god prevailed
occupied by those your fathers hate
media provoking sight and sound
setting the stage as your haventown
internalized out-group hatreds swell
festering unsaid tribal quell
they wear greenish golden armor, you bear skin
theocracy aborts free life, wasting kin
mercenaries eject icy steel, last rites burn
dehumanized forms in bondage, its your turn
emblems of your scorn- what will you do now?
all wear the same face- what will you do now?
all share the same thoughts- what will you do now?
breach, equate
erupt, separate
rip, mutilate
