a
AMC, amoxicillin-clavulanic acid; AMP, ampicillin; FOX, cefoxitin; TIO, ceftiofur; CRO, ceftriaxone; CHL, chloramphenicol; NAL, nalidixic acid; STR, streptomycin; SX, sulfisoxazole; SXT, sulfamethoxazole/trimethoprim; TET, tetracycline.
b
Isolates that showed intermediate resistance to an antimicrobial are categorized as resistant.
