Detection of the eaeA Gene in Escherichia coli Isolated from Broiler Chickens by Polymerase Chain Reaction
The aim of this study was to isolate Escherichia coli from chickens and to determine the presence of the eaeA gene, a virulence factor detected in Escherichia coli, in the isolates by polymerase chain reaction (PCR). Different chicken organs (lung, liver and spleen) were inoculated onto blood agar and biochemical tests were performed on the suspicious isolates. Escherichiacoliwas isolated from ...
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 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 کاملDetection of eaeA, hlyA, stx1 and stx2 genes in pathogenic Escherichia coli isolated from broilers affected with colibacillosis
Background: Foodborne outbreaks associated with shiga toxin-producing Escherichia coli (STEC) have been well documented worldwide. STECs are major causative agents of gastroenteritis in humans that may be complicated by hemorrhagic colitis (HC), hemolytic uremic syndrome (HUS), and thrombotic thrombocytopenia purpura (TTP). OBJECTIVES: The aim of this study was to investigate the presence of vi...
متن کاملPeyer's patch adherence of enteropathogenic Escherichia coli strains in rabbits.
RDEC-1 (serotype O15) is an attaching and effacing strain of rabbit enteropathogenic Escherichia coli (REPEC) that causes diarrhea in postweanling rabbits. It expresses AF/R1 pili that mediate Peyer's patch M-cell adherence. We investigated Peyer's patch adherence, the presence of virulence genes, ileal brush border aggregation, and pilus expression in 9 strains representing several serotypes o...
