Antibiotic Resistance and Virulence Gene Patterns Associated with Avian Pathogenic Escherichia coli (APEC) from Broiler Chickens in Qatar

Avian Pathogenic Escherichia coli (APEC) is the contributing agent behind avian infectious disease colibacillosis, which causes substantial fatalities in poultry industries that has a significant impact on economy and food safety. Several virulence genes have been shown to be concomitant with extraintestinal survival of APEC. This study investigates antibiotic resistance patterns APEC-associated content isolated from non-healthy healthy broiler chickens commercial farm Qatar. A total 158 E. strains were 47 five different organs (air sac, cloacal, kidney, liver, trachea). Based genetic criteria, 65% APEC containing or more genes, 34% non-pathogenic (NPEC) strains. The ompT, hlyF, iroN, tsh, vat, iss, cvi/cva, iucD significantly prevalent all isolates showed 96% at least one 18 antibiotics, high ampicillin, cephalothin, ciprofloxacin, tetracycline, fosfomycin. Our findings indicate prevalence chicken carcasses. Such resistant can spread humans. Hence, special programs are required monitor use antibiotics production
