They were tested against fifteen antibiotics commercially available and frequently used in Pangasius aquaculture, using disk agar diffusion method. High resistance response was observed among both PPF1 and PPF2 isolates to ampicillin (47.22% and 42.86%), followed by cefotaxime (33.33% and 40.00%), respectively. Varying resistance response to all other tested antibiotics such as streptomycin, meropenem, tetracycline, sulfamethoxazole/trimethoprim and nalidixic acid was also observed among E. coli isolates from both factories except to colistin from PPF1 and kanamycin from PPF2.
