Biotype, serotype, and pathogenicity of attaching and effacing enteropathogenic Escherichia coli strains isolated from diarrheic commercial rabbits.
A total of 568 strains of Escherichia coli isolated from healthy and diarrheic rabbits were separated into 11 different biotypes according to the fermentation patterns of four carbohydrates. Strains belonging to biotypes 1 to 3, 6, and 8 induced lesions characteristic for attaching and effacing E. coli (AEEC). They attached to the intestinal epithelium of the terminal small intestine and the la...
متن کاملTyping of intimin (eae) genes in attaching and effacing Escherichia coli strains from monkeys.
Attaching and effacing Escherichia coli (AEEC) strains cause histopathological alterations termed “attaching and effacing (A/E) lesions” (8). The ability to cause A/E lesions is encoded on a large bacterial chromosomal pathogenicity island, the locus of enterocyte effacement (LEE). The central portion of LEE encodes intimin (Eae, 94to 97-kDa outer membrane protein) and Tir, the intimin receptor...
متن کاملLocalized adherence and attaching-effacing properties of nonenteropathogenic serotypes of Escherichia coli.
Traditional enteropathogenic Escherichia coli serotypes demonstrate a plasmid-mediated localized adherence in cultured HeLa or HEp-2 cells and induce an attaching-effacing intestinal lesion, both of which are considered pathognomonic and causes of diarrhea. This study describes three E. coli strains from infantile diarrhea which share these properties but belong to serotypes (O2:H2, O2:H25 and ...
متن کاملCytoskeletal composition of attaching and effacing lesions associated with enteropathogenic Escherichia coli adherence to HeLa cells.
The cytoskeletal lesions associated with enteropathogenic Escherichia coli adhering to cultured HeLa epithelial cells were examined by immunofluorescence microscopy. The microfilament-associated proteins actin, alpha-actinin, talin, and ezrin were localized with adherent enteropathogenic E. coli, whereas tropomyosin, keratin and vimentin (intermediate filaments), tubulin (microtubules), and vin...
متن کاملGenetic diversity of intimin genes of attaching and effacing Escherichia coli strains.
In this study, we determined the sequences of four intimin variant genes detected in attaching and effacing Escherichia coli isolates of human origin. Three of them were novel and were designated eae-eta (eta), eae-iota (iota), and eae-kappa (kappa). The fourth was identical to the recently described eae-zeta (zeta), isolated from a bovine E. coli O84:NM isolate. We compared these sequences wit...
