Escherichia Coli is considered an opportunistic pathogen because generally it is a harmless bacteria, exactly when the intestinal barriers atomic number 18 compromised, even off regular E. coli weed cause infections. Other E. coli cultivate on acquired acrimony factors and jackpot cause disease even in healthy people. They are known as pathogenic E. coli and there are sixer main groups: enter opathogenic, enterotoxigenic, enterohemorragic, enteroinvasive, enteroaggregative, and diffusely adherent. We go forth discuss these much in detail later on. every infections with pathogenic E. coli begin with resolution of intestinal mucosa. This is followed by the virulence factors that cause the symptoms. The prototypic pathogenic E. coli group to discuss is Enteropathogenic.
It was first characterized in 1955 and is about usually associated with infant play.
