Abstract:Objective: To determine prevalence and multiple-antimicrobial-resistant spectrum of Salmonella contamination on chicken carcasses. Methods: According to GB 4789-2008,Salmonellas were separated and identified,and drug resistance of the strains was analyzed using broth dilution method. Results: Salmonella was detected in 34.8%(71/204) of samples. Two Salmonella serovars were identified;predominant ones included Albany(29.6%) and Indiana(50.7%). Most of the Salmonella isolates tested,exhibited resistance to more than three antimicrobial agents used. Twenty-four strains(33.8%) were resistant to three to seven kinds,nineteen strains(26.8%) were resistant to eight to twelve,and twenty-six strains(36.6%) resistant to thirteen and sixteen antibiotics. Resistance to the following antibiotics was common among isolates:nalidixic acid (100%),sulphadiazine(98.6%),ampicillin (97.2%),sulfamethoxazole(85.9%),minocycline (85.9%) and amoxicillin/clavulanic acid (84.5%). Conclusion: High prevalence of Salmonella and the relatively high resistance among the bacteria suggested monitoring of the Salmonella infection and drug resistance on chicken carcass should be strengthened in the future.
