Determination of antibiotic resistance of lactic acid bacteria isolated from traditional Turkish fermented dairy products.

Abstract

In this study, the antibiotic resistance (AR) of lactic acid bacteria (LAB) isolated from traditional Turkish fermented dairy products was investigated. Yogurt, white cheese, tulum cheese, cokelek, camız cream and kefir as dairy products were collected from various supermarkets. Lactic acid bacteria such as <i>Lactobacillus</i> spp., <i>Streptococcus</i> spp., <i>Bifidobacterium</i> spp., and <i>Enterecoccus</i> spp. were isolated from these dairy products. <i>Lactobacillus</i> spp. were resistant to vancomycin (58%), erythromycin (10.8%), tetracycline (4.3%), gentamicin (28%), and ciprofloxacin (26%). <i>Streptococcus</i> spp. were resistant to vancomycin (40%), erythromycin (10%), chloramphenicol (10%), gentamicin (20%), and ciprofloxacin (30%). <i>Bifidobacterium</i> spp. were resistant to vancomycin (60%), E 15 (6.6%), gentamicin (20%), and ciprofloxacin (33%). <i>Enterococcus</i> spp. were resistant to vancomycin (100%), erythromycin (100%), rifampin (100%), and ciprofloxacin (100%). As a result, LAB islated from dairy products in this study showed mostly resistance to vancomycin.
