ANTIBIOTIC SUSCEPTIBILITY PROFILING OF S. AUREUSISOLATED FROM CLINICAL BOVINE MASTITISSONIA TYAGI, PAMELA SINGH AND VIPIN KHASAAbstract Mastitis is among the most common diseases in livestock farming, resulting in substantialfinancial losses associated with decreased milk yield. 53 milk samples were collected from dairy cows withclinical bovine mastitis from Sonipat region, Haryana to investigate the prevalence and antimicrobialsusceptibility of S. aureus responsible for bovine mastitis. Bacterial isolation and identification bymorphologic inspection and biotyping were performed on all the samples. The most common organismisolated in mastitis cases is Staphylococcus aureus (S. aureus), which was found in 41.5% of the cases. Thepresent study showed a significant association of resistant pattern with S.aureus isolated, particularly toAzithromycin (36.3%), Chloroamphenicol (31.8%), Erythromycin (22%) along with Ceftizoxime (22%) andlevofloxacin (22%). As a result, regular resistance monitoring employing antimicrobial sensitivity tests aidsin the selection of effective antimicrobials and the prevention of drug resistance to routinely usedantimicrobials. |
