aMIC Profile: MIC of 11 antibiotics was determined in all the isolates that were either Intermediate or Resistant on AST assay; remaining isolates are labelled S against the MIC strip to which the isolates were susceptible in AST assay. bAntibiotic MIC Strips: XL = Amoxicillin/Clavulanic acid; AM = Ampicillin; AZ = Azithromycin; CL = Chloramphenicol; CT = Cefotaxime (in place of Ceftiofur); FX = Cefoxitin; GM = Gentamicin; NA = Nalidixic Acid; SM = Streptomycin; SX = Sulfisoxazole; TE = Tetracycline. cOnly one representative isolate was used for MIC testing if AST profile was the same.
