espC pathogenicity island of enteropathogenic Escherichia coli encodes an enterotoxin.
At least five proteins are secreted extracellularly by enteropathogenic Escherichia coli (EPEC), a leading cause of infant diarrhea in developing countries. However only one, EspC, is known to be secreted independently of the type III secretion apparatus encoded by genes located within the 35.6-kb locus of enterocyte effacement pathogenicity island. EspC is a member of the autotransporter famil...
متن کاملgenetic evaluation of locus of enterocyte effacement pathogenicity island (lee) in enteropathogenic escherichia coli isolates (epec).
background and objectives: enteropathogenic escherichia coli (epec) divided into two groups typical and atypical (aspect). the main virulence genes are located in a pathogenicity island called lee ( locus of enterocyte effacement ). lee frequently inserted in trna genes of selc , pheu and phev in the bacterial chromosome. tepec and aepec strains have some differences in their pathogenicity. the...
متن کاملEmerging 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 کاملComparative analysis of locus of enterocyte effacement pathogenicity islands of atypical enteropathogenic Escherichia coli.
The pathogenicity of enteropathogenic Escherichia coli (EPEC) is linked to the locus of enterocyte effacement, or LEE, encoding a type III secretion system (T3SS) that directly transfers bacterial effector proteins into eukaryotic cells. Atypical diffusely adhering EPEC (DA-EPEC) strains that harbor homologues of the LEE but lack the EPEC adherence factor plasmid have been increasingly associat...

BACKGROUND AND OBJECTIVES Enteropathogenic Escherichia coli (EPEC) divided into two groups typical and atypical (aspect). The main virulence genes are located in a pathogenicity island called LEE (Locus of Enterocyte Effacement). LEE frequently inserted in tRNA genes of selC, pheU and pheV in the bacterial chromosome. tEPEC and aEPEC strains have some differences in their pathogenicity. The pur...
