Pathogenicity Mechanisms of Escherichia Coli and Salmonella SPP
Abstract
Acute diarrheal diseases are caused by the consumption of contaminated food and water, Salmonella ssp and Escherichia coli are among the main diarrheal agents, describing the virulence factors and pathogenicity mechanisms involved in the seven E. coli serotypes known as E. coli. enteropathogenic coli (ECEP), enterotoxigenic E. coli (ECET), E. coli enteroinvasora (ECEI), shigatoxigenic E. coli (ECST), enteroaggregative E. coli (ECEA) and diffuse adhesion E. coli (ECAD) and E. coli invasive adherent coli (ECAI), by which each type of strain has diff erent mechanisms of pathogenicity and Salmonella is divided into two species, the first Salmonella bongori and the second Salmonella enterica which can be subdivided into 6 different subspecies: subspecies enterica (1), salamae (11), arizonae (lila), diaroniae (IIIb ), houtenae (IV) and indicates (VI); however, S. enterica enteric subspecies with a large number of serotypes and the mechanism of pathogenicity is by two types: the first by the M-cell dependent pathway and the second by the SST3 encoded in two islands of pathogenicity SPis and SPI2, both SST3 do not act independently but collaborate with each other. Through the evolution, the pathogens bacterias have been developed mechanisms that divided in two categories: those that promote the colonization and host invasion and the others that cause damage.
