Antimicrobialsusceptibilityof bacteria isolated from goats with subclinical mastitis in the Southern Marmara region of Turkey

The mastitis of dairy goats is a disease the economic importance worldwide and mostly associated with bacterial infections. aim this study was to isolate bacteriae causing subclinical mastitis, determine susceptibility some clinical isolates against several antimicrobial agents frequently used control in Southern Marmara Region. A total 68 Saanen were for investigation determined by using California Mastitis Test. As result bacteriological analysis milk samples, 30 different bacteria species have been identified non-aureus staphylococci found be predominant rate 22.1%. highest isolation among Escherichia coli (18.9%), Staphylococcus aureus (15.7%), Streptococcus agalactiae (14.2%) epidermidis (7.9%). high including coli, aureus, agalactiae, epidermidis, uberis, Enterococcus faecalis, haemolyticus Mannheimia haemolytica twelve antibiotics disc diffusion method. Bacterial strains analyzed showed sensitivity ofloxacin (87.9%) followed cefuroxime (85.8%) cefazolin (83.6%). In conclusion, still remains problem goats, elimination besides protective measures, determination their antibiotic sensitivities should priority.
