The antibiotic susceptibilities of lactobacilli isolates were determined by Kirby Bauer method on MRS agar media and the classification as S, I and R was based on the recommended breakpoints for diameters of zone of inhibition as specified by EFSA (2012). The experiment was performed three times in triplicates.
