Phenotypic and genotypic characterization of antimicrobial susceptibility of avian pathogenic Escherichia coli isolated from broiler chickens
Aim Avian pathogenic Escherichia coli (APEC) is pathogenic strains of E. coli that are responsible for one of the most common bacterial diseases affecting poultry worldwide. This study was designed to determine the occurrence, antibiotic resistance profile, and antibiotic resistance genes of E. coli isolated from diseased and freshly dead broilers. Materials and Methods In that context, a tot...
متن کاملDetection 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 کاملAntibiotic Resistance in Diarrheagenic Escherichia coli Isolated from Broiler Chickens in Pakistan
Background: Diarrheagenic Escherichia coli (DEC) strains are predominant cause of gastrointestinal tract illnesses. The main objective of the study was to determine antibiotic resistance in various types of DEC isolated from chicken broilers farmed in Pakistan. Methods: A total of 200 feces and 200 meat samples from broiler chickens were collected from the slaughtering shops in Southern Punjab...
متن کاملVirulence factors and clonal relationships among Escherichia coli strains isolated from broiler chickens with cellulitis.
In this study, we compared Escherichia coli isolates from chickens with avian cellulitis with those from feces of healthy chickens. Cellulitis-derived strains presented phenotypic and genotypic characteristics of greater virulence than did the fecal isolates. Phylogenetic analysis by repetitive extragenic palindromic-PCR showed that, in agreement with their virulence characteristics, the cellul...
متن کاملphenotypic and genotypic characterization of enteroaggregative escherichia coli strains isolated from diarrheic children in iran
conclusions these results indicated that eaec strains isolated from iranian children with diarrhea were heterogeneous and showed high resistance rates against commonly used antibiotics, which was similar to that reported in studies performed in other countries. results significant percentage of local eaec strains carried the virulence plasmid genes and formed biofilms. in addition, these strain...
