This study aimed to determinate the susceptibility profile and antimicrobial Multiresistance of Staphylococcus aureus strains from “coalho“ cheese commercialized on Vitória de Santo Antão, Pernambuco, Brazil. The S. aureus strains were obtained from 06 samples of “coalho“ cheese, being 03 pasteurized (Type A) and 03 unpasteurized (Type B) samples. The susceptibility antimicrobial test was performed by disk diffusion method using Erythromycin 15µg, Clindamycin 2µg, Ciprofloxacin 5µg, Gentamicin 10µg, Tetracycline 30µg, Amikacin 30µg, Penicillin G 10 UI, chloramphenicol 30µg, Sulfazotrin 25µg and Cefoxitin 30µg as antimicrobials reference. A total of 48 strains of S. aureus were obtained and submitted to the antimicrobial susceptibility test. All the strains were susceptible to Ciprofloxacin, Gentamicin and Amikacin, while 24 (50%) S. aureus strains presented resistance to Penicillin and thus considered as penicillinase producers and and 5 (10.42%) S. aureus strains were resistant to cefoxitin, being considered as MRSA strains. For the Multiple Antibiotic Resistance (MAR) indexes, were observed values of 0.2, 0.3 and 0.4 correlated with the resistance to two or more antimicrobials class and 0.2 index was the most frequent. As conclusion, there was an occurrence of S. aureus strains with antimicrobial multiresistance in both type A and B “coalho“ cheese samples, emphasizing the importance of the control of the abusive use of antibiotics by supervisory agencies.
