Abstract
U radu je primjenom klasičnih i molekularnih metoda istražena osjetljivost koagulaza-negativnih stafilokoka iz tradicionalnih fermentiranih kobasica na antimikrobne spojeve. Pomoću disk-difuzijskog i epsilometar testa ispitana je osjetljivost izolata na vankomicin, ampicilin, eritromicin, tetraciklin, gentamicin i oksacilin. Metodom je PCR u izolatima određena prisutnost gena za rezistenciju, i to mecA, ermB, tetK i tetM. Utvrđene su sljedeće vrste koagulaza-negativnih stafilokoka: Staphylococcus epidermidis (69 %), S. capitis (5 %) i S. warneri (2.5 %). Ukupno je 44,4 % izolata S. epidermidis pokazalo fenotipsku rezistenciju na tetraciklin i eritromicin. Prisutnost gena tetK ili tetM potvrđena je u 8 izolata S. epidermidis. Iako S. epidermidis nije uobičajeni uzročnik trovanja hranom, njegova je prisutnost u hrani važna za javno zdravstvo zbog mogućeg širenja antimikrobne rezistencije. Dobiveni rezultati pokazuju da spontanom fermentacijom mesa mogu nastati proizvodi opasni za zdravlje potrošača.
