From: Detection of antibiotic resistance in probiotics of dietary supplements
The antibiotic susceptibility profile of probiotic bacteria in the dietary supplements. (a) Representative MRS agar plates of bacteria lawn of Bi, Bn, Bg, Cn and L dietary supplements layered with antibiotic discs showing susceptibility towards multiple antibiotics as characterized by the presence of ‘clear’ inhibition zones. (b) Mean inhibition zones measured from the bacteria lawn of Bi, Bn, Bg, Cn and L dietary supplements layered with the respective antibiotic discs. Error bars represent standard error of the mean (n ≥ 2) and (*) represents inhibition zone present in only certain batches of bacteria in the respective dietary supplement
