Staphylococcus spp. isolated from samples of Minas cheese traditionally manufactured following artisan procedures were identified using molecular techniques and further analyzed using PCR and specific primers for the detection of classic enterotoxins (SEA, SEB, SEC, SED, and SEE) and toxic shock syndrome toxin-1 (TSST-1). Specific sea, sec, sed, and see genes were identified using multiplex PCR, whereas seb and tst genes were detected by uniplex PCR. In vitro antagonism with Lactobacillus spp. was evaluated to assess antimicrobial susceptibility. Classic enterotoxins and TSST-1 genes were not detected. The antimicrobials sulfonamide, penicillin, ceftzadime, and oxacillin showed higher resistance rates in the antibiogram (100%, 80%, 60%, and 40%, respectively), whereas other antimicrobials were effective in percentages above 70%. Lactobacillus spp. were able to inhibit Staphylococcus spp. in vitro. Thus, our results indicated that the isolated Staphylococcus spp. were sensitive to the most common antimicrobials tested and were inhibited by Lactobacillus spp.Downloads
