A study was carried out in 2000 quarters milk samples of 500 lactating buffaloes in Durg district of Chhattisgarh State, India. 330 (66.00%) animals were found to be positive for sub clinical mastitis (SCM) by Modified White Side Test (MWST), 343 (68.60%) by Modified California Mastitis Test (MCMT) and 360 (72.00%) by Somatic Cell Count (SCC). The overall quarter-wise prevalence of SCM was 38.99% by MWST, 42.00% by MCMT and 45.00% by SCC. 1.9% quarters were found blind. Single quarters and hind quarters involvement was maximum. In regard to stage of lactation infection rate was higher during the late lactation followed by early and mid stage of lactation. The prevalence was highest during third and fourth lactation and at 3 to 9 years of age. Among the microorganisms isolated the Staphylococcus sp. occupied prime position. According to microbial sensitivity test, maximum number of isolates (27.27%) showed sensitivity to cefotaxime antibiotic whereas most of the isolates were resistant to ampicillin.
