Abstract :Three hundred bovine milk samples with mastitis were used. Eighty-five (28.33%) strains were identified as Staphylococcus aureus whereas 60 (20.00%) strains were isolated as coagulase negative staphylococcus. Bacteriological cultures of coagulase negative staphylococcus were identified as 20 (33.33%) strains of S. hyicus, 16 (26.66%) strains of S. chromogenes, 9 (15.00%) strains of S. epidermidis, 5 (8.33%) strains of S. haemolyticus, 4 (6.66%) strains of S. sciuri, 3 (5.00%) strains of S. lentis and 3 (5.00%) strains of S. cohnii subsp. cohnii. The antibiotic susceptibility test results showed that Staphylococcus aureus strains were susceptible to ciprofloxacin (100.00%), neomycin + bacitracin + tetracycline (100.00%), kanamycin (85.00%), cefquinome (85.00%) and amoxycillin + clavulanic acid (84.00%), while they were resistant to penicillin (95.00%) and oxacillin (60.00%). Beside this, it has been found that the coagulase negative staphylococcus strains were susceptible to cefquinome (100.00%) and neomycin + bacitracin + tetracycline (100.00%), but resistant to penicillin (90.00%) and oxacillin (73.00%).Keywords : Mastitis, Staphylococcus aureus, coagulase negative staphylococcus identification, antimicrobial susceptibility testing
