Notes: Data are number (%) with disparity in % antibiotic resistance between fox AmpC (+ve) and fox AmpC (−ve) analyzed by chi-square (χ2) or Fischer’s exact test. P<0.05 was considered to be significant.
Abbreviations: AMP, ampicillin; AUG, augmentin; COT, cotrimoxazole; GEN, gentamicin; IMP, imipenem; NAL, nalidixic acid; ND, not determined; NIT, nitrofurantoin; OFL, ofloxacin; TET, tetracycline.
