| English abstract | In this study, 201 strains of S. aureus were isolated from crude milk and submitted to antibiotic resistance by the disc diffusion method using impregnated paper discs with the following antibiotics: amikacin, ampicillin, cephalotin, cephoxitin, chloramphenicol, clindamycin, oxacylin, penicillin, tetracycline, tobramycin and vancomycin. With the exception of 88 (43.8%), 90 (44.8%), 24 (11.9%) e 40 (19.9%) resistant strains to penicillin, ampicillin, chloramphenicol and tetracycline, respectively, it was verified that most of the 201 strains (95% or more) showed sensitivity to the others tested antibiotics. The strains resistant to these four antibiotics were phage-typified with the basic international set of phages for S. aureus of human and bovine origin and showed predominant sensitivity to the phage of the groups III and III/No Classified from the human basic set and to the phage groups III, IV and to the association III/IV from the bovine set |

Com exceção de 88 (43,8%), 90 (44,8%), 24 (11,9%) e 40 (19,9%) cepas resistentes à penicilina, ampicilina, cloranfenicol e tetraciclina, respectivamente, a maioria das 201 cepas (95% ou mais) foi sensível aos antibióticos utilizados. As cepas resistentes a estes quatro antibióticos foram fagotipadas, empregando-se os Conjuntos Básicos Internacionais de bacteriófagos para cepas de origem humana e bovina, verificando-se que houve predomínio de cepas sensíveis a fagos dos grupos III e III/NC do conjunto básico humano e a fagos dos grupos III, IV e da associação III/IV do conjunto bovino |
