The antimicrobial resistance in food producing animals is a global problem particularly in developing countries and the indiscriminate use of antimicrobial agents is a major concern for the emergence of resistant zoonotic bacterial pathogens. The Coagulase positive (CPS) and Coagulase negative Staphylococci (CNS) strains, opportunistic pathogens, which commonly resides on the coverings of humans and animals and cause wide range of infections as well as food poisoning in both humans and animals Hence, the present study was aimed to detect presence of methicillin resistant as well as Vancomycin resistant Staphylococcus aureus and CNS in a total of 100 raw milk samples by phenotypic methods i.e. disc agar diffusion tests. Among 57 Staphylococcus isolates, 42 and 15 isolates were confirmed as S. aureus and CNS. Out of 42 S. aureus strains, 10 were identified as methicillin resistant (MRSA) and 5 as Vancomycin resistant (VRSA). Among 15 CNS strains, 5 and 4 were identified as methicillin resistant (MR-CNS) and Vancomycin resistant (VR-CNS). The presence of antibiotic resistance among S. aureus and CNS in veterinary may cause hazard for human health via food chain or through direct transmission of resistant pathogens between humans and animals.
