There were seven drug classes tested: 1. Beta-lactam (AMC, Amoxycillin + Clavulanic acid; AMP, Ampicillin; FOX, Cefoxitin; CRO, Ceftriaxone; TIO, Ceftiofur), 2. Aminoglycosides (GEN, Gentamicin; STR, Streptomycin), 3. Quinolones (NAL, Nalidixic acid; CIP, Ciprofloxacin), 4. Sulfonamides (SSS, Sulfisoxazole; SXT, Trimethoprim sulfamethoxazole), 5. Macrolides (AZM, Azithromycin), 6. Phenicols (CHL, Chloramphenicol), 7. Tetracyclines (TET, Tetracycline). Drugs were grouped in classes by clear/grey areas.
R, Resistant.
aRatio is defined as the number of isolates of the same resistance pattern over the total number of isolates.
All the antimicrobials belonging to the same drug class were placed next to each other and separated from those in other drug classes by shading.
