A total of 2340 mammary glands of 585 primiparous and pluriparous lactating buffaloes in different stages of lactation were examined with California Mastitis Test (CMT) and laboratory examination was carried out to identify the most prevalent micro- organisms in clinical and sub-clinical mastitis. The physical examination revealed 2.61 per cent blind teats and CMT revealed 6.71 per cent positive quarters for mastitis. Microbiological examination of 157 sub-clinical mastitis milk sample, and 46 clinical mastitis milk samples was carried out. There was high occurrence of streptococci (35.46%) followed by staphylococci (33.99%), E. coli (27.09%), pseudomonas spp. (1.97%) and Corynebacterium pyogenes (1.48%). The in vitro sensitivity revealed kanamycin (82.6%) highly effective against various isolates followed by gentamicin (53.0%).
