Abstract:
Salmonella is a foodborne pathogen having a worldwide public health concern. The present study was undertaken to characterize Salmonella species of animal origin based on cultural isolation, molecular confirmation of serovars and their virulence profiles. A total of 516 samples comprising poultry cloacal swabs (249), raw foods of animal origin (118 chicken samples, 65 mutton and 30 pork), poultry liver swabs (17) and poultry farm water samples (37) were examined for presence of Salmonella serovars. Overall prevalence of Salmonella isolates was found to be 4.06% (21/516) with highest prevalence in chicken samples (6/118, 5.08%) followed by cloacal swabs of poultry (12/249, 4.81%), mutton (2/65, 3.07%) and pork (1/30, 3.33%). All the isolates carried all the 7 virulence genes i.e. invA, invH, sopB, sopE & stn (100%), while pefA gene was found only in S. typhimurium isolates and sefC gene was found only in S. enteritidis isolates.
