The Antibiotic resistance of lactic acid bacteria isolated from kefir made from Etawah goat milk

Abstract

The objectives of the study were to determine the antibiotic resistance of Lactic Acid Bacteria (LAB) isolated from kefir made from Etawah goat milk. A total of 25 isolates were isolated from etawah goat milk, yogurt and kefir. LAB isolates were resistant to Ceftazidime (Caz, 100%), Ceftriaxone (Cro, 100%), Clindamycin (Da, 100%), Lincomycin (Li, 100%), Rifampicin (Rd, 100%) and Tobramycin (Tob, 100%). The bacteria were susceptible to Sulphamethoxazole-Trimethoprim (Sxt, 60%) and Tetracycline (Te, 40%). The percentage of antibiotic resistance of LAB was found to be in the range between 40 to 100%. The presence of antibiotic resistance in good bacteria may introduce the horizontal genetic transfer to bad bacteria which has the potential to disrupt human health.
