The study was carried out with an objective to establish a baseline for antimicrobial susceptibility of Enterococcus isolates recovered from healthy poultry faeces in Bikaner region. The isolates were subjected to antibiotic sensitivity test by Kirby Bauer disk diffusion method using 19 different antibiotics belonging to different classes. Based on the resistance pattern of the isolates, the Multiple Antibiotic Resistance (MAR) Index was calculated. The results of the study revealed that almost all of the isolates exhibited Multi Drug Resistance (MDR) character and all the isolates had a very high MAR Index, suggesting the origin of the isolates to be of high antibiotic usage.
