Antimicrobial Resistance Properties, Biofilm, and mecA Gene Presence in Staphylococcus Aureus Isolated from Raw Milk Sold in Van, Türkiye

Staphylococcus aureus can cause foodborne poisoning and form biofilms, reducing enterotoxin production the penetration rate of antibiotics. Therefore, infections poisonings caused by S. be difficult to treat. The aim this study was investigate antibiotic resistance levels isolates obtained from raw milk presence biofilm mecA gene reveal risk public health. isolated in 30 (30%) 100 samples Van province. A total 48 were samples. All (100%) resistant penicillin G cefoxitin, 4 (8.33%) sulfamethoxazole-trimethoprim chloramphenicol, 25 (52.08%) erythromycin. found susceptible ceftriaxone. In addition, 26 (54.16%) at least 3 strains cefoxitin also intermediate one Biofilm genes detected 18 (37.5%). Twelve biofilm-forming contain icaA (66.6%), icaD (16.6%) other bap (16.6%). Three three together. It determined that only 2 contained gene. containing genes. conclusion, fact had high resistance, genes, methicillin showed may a serious health problem.
