Shiga toxin-producing Escherichia coli (STEC) strains and is considered to be most common food-borne zoonotic pathogen causing various disease conditions in both animals and humans. At present antimicrobial resistance among these isolates is a major problem. Hence a small study was planned to identify antimicrobial resistance or sensitivity against STEC isolates obtained from animal faecal samples of different livestock species against selected antibiotics like Ampicillin (Amp) 10µg/ disc, Cephalothin (Cef) 100 µg/disc, Chloromphenicol (Chl) 30µg/disc, Colistin (Cst) 25µg/disc, Gentamycin (Gen) 10µg/ disc, Kanamycin (K) 30µg/disc, Sulphonamides (sul) 10µg/ disc, Streptomycin (S) 10µg/disc, Tetracycline (Tet) 30µg/disc and Trimethoprim (Tmp) 10µg/ disc. Antimicrobial susceptibility of the isolates was established by the disk diffusion assay with Muller Hinton agar in accordance with French National Antibiogram Committee Guidelines. The resistance was highest to Ampicillin, Cepahlothin (100%) followed by Tetracycline (95.5%), Streptomycin (93.3%), Sulphonamides (89.9%), Trimethoprim (84.4%), Colistin (32.9%), Kanamycin (21.2), Chloromphenicol (17.3%) and least resistant to Gentamycin (8.3%). The STEC isolates were more sensitive to Gentamycin, Chloromphenicol, Colistin, Kanamycin, Trimethoprim and sulphonamides.
