Abstract: The aim of the presented research is to determine the antibiotic sensitivity and resistance of the microorganisms causing subclinical mastitis in dairy sheep. To achieve this, 120 milk samples from 4 farms located in 3 regions of the country were obtained and examined. The results showed that the isolates from the different farms were sensitive to Ciprofloxacin and Enrofloxacin, as well as to the combination Sulfamethoxazole+Trimethoprim. Resistance was found most often to Kanamycin, Colistin and antibiotics from the penicillin group.
