Antimicrobial Resistance Profile of Salmonella Serovars Isolated from Chicken Meat

A. H. Shah and N. A. Korejo


The study was designed to investigate the prevalence and antibiotic resistance profile of Salmonella spp. in broiler chicken meat sold in the Karachi City-Pakistan. A total of 160 meat samples were randomly collected from different retail markets and examined for the presence of various species of salmonella. The prevalence rate recorded was 48.75%. Different species of salmonella detected were S. enteritidis, S. typhi, S. pullorum and S. typhimurium (48.71, 20.51, 20.51 and 10.25% respectively). All the isolates were resistant to ampicillin, streptomycin, cefotaxime, kanamycin, neomycin, nalidixic acid, tetracycline, bacitracin, erythromycin, novobiocin, and spectinomycin. However, the isolates showed sensitivity to ceftazidime, gentamicin, tobramycin, ciprofloxacin, ofloxacin and chloramphenicol. In conclusion, the chicken meat may be a source of multiple antimicrobial-resistant salmonella for human infections.
