Abstract:
Livestock industries are growing tremendously along with the human population. India has rapidly increased its beef exports. The maintenance of quality of food products derived from these animals is on high consideration. In this investigation the prevalence of
Salmonella species was performed through phenotypic and genotypic characterization in beef samples (n=100) collected from butcher shops locally in Bareilly. A total of 8 isolates (4.0%, n = 8) were identified via. phenotypic assay (H
2S production on TSI, Lysine decarboxylase assay, acid production from lactose and sucrose, IMViC assay). The genotypic characterization was performed using Polymerase Chain Reaction (PCR) assay targeting
invA gene (389 bp). Furthermore, antibacterial resistance profile of all
Salmonella isolates (n=8) was determined against seven antibiotics (ampicillin, cephalexin, ciprofloxacin, nalidixic acid, gentamicin, tetracycline and streptomycin. The antibiotic susceptibility profiles confirmed drug resistance among 50% of
Salmonella isolates. It was observed that 37.5% of
Salmonella isolates were resistant to the ampicillin and ciprofloxacin whereas a slight lower resistance of 25.0% against ciprofloxacin and tetracycline was observed. No resistance was observed against nalidixic acid, gentamycin and streptomycin. Overall resistance to multiple drugs (≥ 3) was recorded in 25.0% isolated strains.
