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 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 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 کاملCloning and characterization of the eae gene from a dog attaching and effacing Escherichia coli strain 4221.
We have cloned and determined the nucleotide sequence of the eae gene from a dog attaching and effacing (A/E) Escherichia coli (DEPEC) strain 4221. When comparing the predicted amino acid sequence of the eaeDEPEC to that of the Eae proteins from enteropathogenic E. coli (EPEC), enterohaemorrhagic E. coli O157:H7 (EHEC), Citrobacter freundii biotype 4280, and a swine A/E E. coli strain O45 (PEPE...
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...
