Emerging Enteropathogenic Escherichia coli Strains?
Escherichia coli strains of nonenteropathogenic serogroups carrying eae but lacking the enteropathogenic E. coli adherence factor plasmid and Shiga toxin DNA probe sequences were isolated from patients (children, adults, and AIDS patients) with and without diarrhea in Brazil. Although diverse in phenotype and genotype, some strains are potentially diarrheagenic.
متن کاملAtypical Enteropathogenic Escherichia coli: Typical Pathogens?
scherichia coli is both the most abundant facultative commensal of the human gastrointestinal tract and the most common bacterial cause of human diarrhea (1). However, precise recognition of E. coli pathotypes remains problematic. Enteropathogenic E. coli (EPEC), classically associated with outbreaks of infant diarrhea, harbors distinctive chromosomal (the locus of enterocyte effacement, or LEE...
متن کاملCellular responses to enteropathogenic Escherichia coli infection.
Enteropathogenic Escherichia coli (EPEC), first described in the 1940's and 1950's, remain an important cause of severe infantile diarrhoea in many parts of the developing world. EPEC do not produce enterotoxins and are not invasive; instead their virulence depends upon exploitation of host cell signalling pathways and the host cell cytoskeleton both as a means of colonizing mucosal surfaces of...
متن کاملEnteropathogenic Escherichia coli O157 Strains from Brazil
We describe two serogroup O157 Escherichia coli strains from Brazilian infants with diarrhea. A variety of assays indicate that these strains belong to the enteropathogenic, not the enterohemorrhagic, pathotype. These strains possess a novel bfpA allele encoding the type IV pilin characteristic of typical enteropathogenic E. coli strains. Our results emphasize the pitfalls of classifying pathog...
متن کاملMouse model of enteropathogenic Escherichia coli infection.
Enteropathogenic Escherichia coli (EPEC) is an important cause of diarrhea in humans. EPEC infection of cultured intestinal epithelial cells induces attaching and effacing (A/E) lesions, alters intestinal ion transport, increases paracellular permeability, and stimulates inflammation. The lack of a small-animal model has restricted in vivo studies examining EPEC-host interactions. The aim of th...
