[a] Antibiotic discs of: A, ampicillin (10 μg); Amc, amoxicillin with clavulanic acid (20/10 μg); C, chloramphenicol (30 μg); CIP, ciprofloxacin (5 μg); Cft, cefotaxime (30 µg); Er, erythromycin (15 µg); Gm, gentamicin (10 µg); Mth, methicillin (10 µg); NA, nalidixic acid (30 μg); NOR, norfloxacin (10 μg); T, tetracycline (30 μg); Van, vancomycin (16 µg). Lowest MIC values indicate the highest inhibitory effect
