Pathogenic Escherichia coli
Escherichia coli (/ˌɛʃəˈrɪkiə ˈkoʊlɪ/ Anglicized to /ˌɛʃəˈrɪkiə ˈkoʊlaɪ/; commonly abbreviated E. coli) is a gram-negative, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms (endotherms). Most E. coli strains are harmless, but some serotypes are pathogenic and can cause serious food poisoning in humans, and are occasionally responsible for product recalls. The harmless strains are part of the normal flora of the gut, and can benefit their hosts by producing vitamin K2, and by preventing the establishment of pathogenic bacteria within the intestine.
Introduction
E. coli and related bacteria constitute about 0.1% of gut flora, and fecal–oral transmission is the major route through which pathogenic strains of the bacterium cause disease. Cells are able to survive outside the body for a limited amount of time, which makes them ideal indicator organisms to test environmental samples for fecal contamination. The bacterium can also be grown easily and inexpensively in a laboratory setting, and has been intensively investigated for over 60 years. E. coli is the most widely studied prokaryotic model organism, and an important species in the fields of biotechnology and microbiology, where it has served as the host organism for the majority of work with recombinant DNA.

FALSA MORAL
by: OBKLA MAS BELLA HISTORIA
QUE SE PUEDE CONTAR
LLEVA ESCRITO EL DOLOR
QUE PROVOCA UN AMOR
QUE NADIE ENTENDERÁ
SIEMPRE TODO A ESCONDIDAS
SIEMPRE MIRANDO ATRÁS
SÓLO LA OSCURIDAD
PUEDE SER NUESTRO HOGAR
DONDE CRECERÁ ESTE AMOR
Y NO... NO QUIERO MAS CLASES DE FALSA MORAL
QUE NADIE ES CULPABLE POR AMAR
EN MI PECHO NO LATE LA RAZÓN
SÓLO EL MAS SINCERO Y PURO AMOR
NO HAY MAR EN EL MUNDO
NI FUERZA CAPAZ
QUE PUEDA ESTE FUEGO APAGAR
SÓLO EL TIEMPO PUEDE SER NUESTRO JUEZ
TE QUISE, QUIERO Y QUERRÉ
QUE DIFÍCIL LO NUESTRO
QUE BONITO A LA VEZ
ES TAN DURO TENER
QUE BUSCAR LOS PORQUES
A ESTA SITUACIÓN
NUESTRO AMOR ES LA ISLA
EL TESORO ERES TÚ... OH DIOS
CON MI VIDA DARÉ
SÓLO EL BRAZO A TORCER
BIEN LO SABES, MI AMOR
NO... NO QUIERO MAS CLASES DE FALSA MORAL
QUE NADIE ES CULPABLE POR AMAR
EN MI PECHO NO LATE LA RAZÓN
SÓLO EL MAS SINCERO Y PURO AMOR
NO HAY MAR EN EL MUNDO
NI FUERZA CAPAZ
QUE PUEDA ESTE FUEGO APAGAR
SÓLO EL TIEMPO PUEDE SER NUESTRO JUEZ
TE QUISE, QUIERO Y QUERRÉ
NO... NO QUIERO MAS CLASES DE FALSA MORAL
QUE NADIE ES CULPABLE POR AMAR
EN MI PECHO NO LATE LA RAZÓN
SÓLO EL MAS SINCERO Y PURO AMOR
NO HAY MAR EN EL MUNDO
NI FUERZA CAPAZ
QUE PUEDA ESTE FUEGO APAGAR
SÓLO EL TIEMPO PUEDE SER NUESTRO JUEZ
TE QUISE, QUIERO Y QUERRÉ
