Özet

The current study aimed at the determination of resistances of lactic acid bacteria against antibiotics, which isolated from some commercial probiotic foods. Lactobacillus spp., Lactobacillus acidophilus and Bifidobacterium spp. were isolated and their antibiotic resistances were analysed by Kirby-Bauer Disc Diffusion method. While Lactobacillus spp. isolates were determined resistant to vancomycin (20%), tetracycline (20%), ampicillin (20%), gentamicin (20%) and ciprofloxacin (80%), these isolates were found susceptible to chloramphenicol (100%), erythromycin (100%) and nitrofurantoin (100%). As regards to L. acidophilus, while resistance to gentamicin (25%) and ciprofloxacin (75%) was determined, all isolates of L. acidophilus were found susceptible to vancomycin, chloramphenicol, rifampicin, tetracycline, erythromycin, nitrofurantoin and ampicillin. Bifidobacterium spp. isolate were found resistant to vancomycin, tetracycline, ampicillin and ciprofloxacin, whereas isolates were sensitive to chloramphenicol, erythromycin, nitrofurantoin and gentamicin.
