N2  - This study was carried out in 256 cows which were in lactation period in Sarıkamış town of Kars. The animals wereexamined c1inically in the point of mastitis and inflamational changes of udders were determined with California Mastitis Test (CMT).Consequently, mastitis were diagnosed in 61 of 256 cows (23.8%). 79 milk sample were taken from 61 cows which were positive inCMT test. As a result of microbiological examination, while agent was isolated in 67 of all samples (84.8%), no bacterial agent was notisolated in 12 samples (15.2%). While Staphylococcus aureus was the most determined bacterium with the percentage of 34.3%,coagulase negative staphylococcus (KNS) followed that whit the persentage of 28.3%. Except these two groups of microorganism,Escherichia coliwas isolated in the 5.9% and Streptococcus spp. were isolated in the 16.4% of the samples. In 14 (33.3%) S. aureusand 4 ( 9.5%) KNS strains, of all isolated staphylococcus strains, ß-lacternase was found positive. In the study the resistance ofstaphylococcus strains against antibiotics were determined as follows; 59.5% penicillin, 38.1% amoxicillin, 7.1% amoxicillin-c1avulonicacid, 4.8% c1oxacillin, 11.9% enrofloxacin and all strains were found sensitiye against vancomicin. The ô-lactarnase activity of thestrains was determined to have an important role in resistance against ô-lactarn group antibiotics.
