The present study was conducted on clinical cases of mastitis in cattle where isolation, identification of udder pathogens and antimicrobial susceptibility of isolated staphylococci was carried out. A total of 565 quarters milk samples of 142 cattle were investigated and among these 394 quarters were found to be infected. Occurrence of mastitis was found to be highest during third and fourth parity and up to first month of post-partum. The highest frequency of Staphylococcus spp. (60.04%) was observed followed by Streptococci spp. (24.02%), E. coli (10.26%) and other bacteria (5.68%). Antimicrobial susceptibility testing revealed that highest resistance of Staphylococcus spp. was towards penicillins; cloxacillin, oxacillin, penicillin, ampicillin, amoxicillin and oxytetracycline, while sensitivity was higher towards methicillin, cefuroxime, lincomycin and gentamicin. High occurrence of mastitis needs timely and appropriate strategies to control the spread of this disease. Antimicrobial susceptibility testing should be performed for selection of effective antimicrobial therapy and the judicious use of antibiotics should be done to reduce resistance against antimicrobials in pathogens.
