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.
