Abstract:
In this study lactic acid bacteria (LAB) were isolated from raw milk of Badri cattle to investigate antibiotic resistance profile. A total of 47 non-hemolytic LAB could be isolated from 62 raw milk samples. The percentage of antibiotic resistance ranged from 2-68% in the LAB isolates obtained. High resistance was observed against cefixime (68.08) and penicillin (51.06), followed by streptomycin (17.02), co-trimoxazole (8.51), levofloxacin (4.25) and low in amoxyclav (2.13), azithromycin (2.13). Nearly 82.97% isolates had MAR Index of 0.2 or less. Species wise resistance profile demonstrated Lactobacillus to be the least and Leuconostoc to be the most resistant.
