Abstract: The development of antibiotic resistance is a serious problem in both humans and animals. Antibiotic resistance is generally linked with the misuse or overuse of antibiotics, which may lead to reduced efficacy of treatment and a prolonged recovery period. The objective of the present investigation was to study the antibiogram pattern of E. coli isolates obtained from the diarrhoeic goats. A total of 200 faecal samples were collected from the diarrhoeic goats of four different districts (Durg, Raipur, Rajnandgaon and Dhamtari) in Chhattisgarh. The faecal samples were processed for isolation and identification of E. coli. For assessment of the resistance pattern of E. coli isolates, 14 antibiotics of different concentrations were tested. Out of 200 faecal samples, 144 samples were determined to be positive for E. coli. These E. coli isolates exhibited the highest resistance to penicillin (100%) and the least resistance to ofloxacin (6.25%). A total of 131 E. coli (90.97%) isolates had an MAR index of more than 0.2, which suggested the injudicious use of the antibiotics.
