Abstract:

The study focused on the prevalence of Staphylococcus aureus and resistant strains in goat milk samples. In this study, 100 individual goat raw milk samples were collected. A total of 39 (39%) isolates were recovered. Strains identified as Staphylococcus aureus were further analysed by the polymerase chain reaction method for detection of the mecA gene. Among the 39 isolates 28 (71.7%) samples showed positive results for coagulase test, 31 (79.4%) were of biofilm producers and 21 (53.8%) samples positive for mecA gene. Isolates showed maximum sensitivity as followed; Cefoxitin (83.2%), Cephalothin (72%), Kanamycin (76.3%), Choramphenicol (75.8%), Erythromycin (71.55%) and Gentamicin (70.8%) & resistance against Nalidixic acid (85.8%), Polymixin B (82.6%) and Penicillin G (70.5%). Vancomycin (36.7%) resistant isolates also note worth in present study. Isolates of S. aureus revealed the pathogenicity and resistance against the existing antibiotics. Study shows that goat milk also having equal chances of transmission to consumers via contaminated milk consumption. Hence, to improve the quality of milk and to prevent S. aureus contamination more hygienic measures should be implemented from point of production to consumption.
