During 1993-1997, the sensitivity to antibiotics was studied in 648 strains of the mastitis bacterial causative agents by the disk-agar diffusion test. Of them, Streptoccocus sp. represented 40.4%, Staphyloccocus aureus 21.3%, coagulase-negative staphyloccoci 15.7%, and other agents 22.5%. In 1995-97, there was a good sensitivity in the bacteria Steptoccocus sp.: Streptoccocus dysgalactiae showed 3.7% resistance against penicillin, oxacillin and chloramphenikol and 74% resistance
