Abstract:
The study was carried out to investigate the incidence and antimicrobial susceptibility pattern of Staphylococcus aureus. Further isolates were screened for presence of methicillin resistant Staphylococcus aureus (MRSA) isolated from bovine mastitis in Chhattisgarh. A total of 300 milk samples were collected from clinical cases of mastitis. Milk samples were processed for isolation and identification of Staphylococcus aureus followed by Antibiogram using standard bacteriological procedures. Overall, incidence of Staphylococcus aureus was 54.66%. Drug sensitivity revealed 83.5% resistance against penicillins followed by methicillin 31.09%, gentamicin 17.6%, tetracycline 12.8%, cefepime 26.82%, erythromycin 11.58%, clindamycin 4.8%, amoxyclav 60.9%, amoxicillin 68.29%, linezolid 3.04% and vancomycin (0.006%). Results indicated that these isolates exhibit the multidrug resistant (MDR) pattern which is an alarming situation to both human and animal health. However, present findings are useful in selection of antibiotics in the treatment of bovine mastitis.
