Perfil de resistência antimicrobiana de cepas de Staphylococcus sp. isoladas de queijo tipo coalho / Antimicrobial resistance profile of Staphylococcus sp. strains isolated from type coalho cheese

ABSTRACT

The antimicrobial resistance profile of 45 Staphylococcus strains isolated from 10 samples of Brazilian type "coalho" cheese was evaluated against eight antibiotics used either in human or in veterinarian medicine. The tested antibiotics decreasing resistance degree was penicillin (100.0 percent), tetracycline (91.0 percent), vancomycin (75.5 percent), gentamicin (71.1 percent), oxacillin (66.7 percent), erythromycin (60.0 percent), cephalothin (48.9 percent) and sulphazothrin (26.7 percent). The high frequency of Staphylococcus strains presenting resistance to the tested antibiotics, emphasizes the importance of the control of the abusive use of antibiotics by medical and veterinarian subjects.
