  1. aThe percentage value indicates the frequency of E. coli isolates from different sources. bThe percentage value indicates the frequency of NA (nalidixic acid)- or CIP (ciprofloxacin)-resistant isolates from the collected E. coli isolates using disk diffusion and broth microdilution methods. Note that all isolates that showed resistance against ciprofloxacin also showed resistance against nalidixic acid
