Cytoskeletal 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 کاملExperimental infection of young chicks with attaching and effacing Escherichia coli.
Young chicks were inoculated with six different strains of attaching and effacing Escherichia coli isolated from the feces of calves, pigs, chicks, and humans. Colibacilli of some serotypes had colonized the cecum of chicks by 7 days after inoculation. The characteristic lesions associated with bacterial attachment were also seen on the mucosal surface of the cecum. Electron microscopy revealed...
متن کاملPrevalence of enterohaemorrhagic Escherichia coli from serotype O157 and other attaching and effacing Escherichia coli on bovine carcasses in Algeria.
AIMS Bovine meat is the principal source of human contamination of attaching and effacing Escherichia coli, including enterohaemorrhagic E. coli O157. The aim was to study the prevalence of these strains on bovine carcasses in Algeria. METHODS AND RESULTS Two-hundred and thirty carcasses were swabbed and analysed by classical microbiological methods for total E. coli counts and for the presen...
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...
متن کاملStrains of Escherichia coli O157:H8 from human diarrhoea belong to attaching and effacing class of E coli.
AIMS To determine whether 17 Escherichia coli O157:H8 strains isolated from patients with diarrhoea in the United Kingdom were putative pathogens. METHODS The strains had been isolated by the use of O157 antiserum, available for the detection of Vero cytotoxin (VT) producing strains of E coli O157 that are usually of flagellar (H) type 7, but may also be non-motile. The strains were examined ...
