Abstract
The current study included collecting clocae samples from poultry within Wasit Governorate’s farms. It aimed to isolate salmonella from broiler chickens and to determine the pattern of resistance to antimicrobial drug besides to detect of Quinolone Resistance genes. The results showed isolation of (3) types of Salmonella (s. gallinarum s.typhimurium, s.enteritidis). The highest percentage of resistance isolates to tested antibiotics (nalidixic acid, ciprofloxacin ofloxacin, enrofloxacin, levofloxacin) depending on disc diffusion test, were as follow (81%), (78.26) and (91.66%)respectively. The remaining small percentage of the isolates were sensitive to all quinolones. On the other hand, The results of the molecular diagnostics that were conducted found that all antibiotic-resistant strains contain qnr B and iaa (6) ib gene.
