Bovine mastitis poses great economic threat to dairy industry affecting livestock farmers across the globe. Various species of staphylococci bacteria are one of the major pathogen responsible for the bovine mastitis. The present investigation was carried out to assess in vitro antibiogram of field isolates of coagulase positive and coagulase negative staphylococci (CoPS and CoNS, respectively), isolated from 95 bovine mastitis cases in Banaskantha district of Gujarat state. Milk samples were screened for the presence of Staphylococcus species by cultural, colonial, microscopic and biochemical characteristics and finally, 29 samples (30.53 %) were confirmed for the same. Coagulase test was performed and 12 CoPS (41.38%) and 17 CoNS (58.62%) strains were found. All 12 CoPS were S. aureus as confirmed by PCR. Antibiogram trend against nine commonly used antimicrobial drugs for treatment of bovine mastitis in the region showed that both CoPS and CoNS groups were highly resistant to penicillin-G (83.33 and 88.24 %, respectively) and tetracycline (83.33 and 76.47%, respectively).
