Abstract

In this paper we determined bovine and porcine bile tolerance of two Lactobacillus salivarius strains isolated from dental root canal: G1 and G2 compared to two probiotic strains: Lactobacillus salivarius probiotic and Lactobacillus rhamnosus GG. Determination of bile tolerance was done with Minimum Inhibiting Concentration method (MIC). The bovine bile was better tolerated compared with porcine bile by all Lactobacillus investigated strains. Differences between strains regarding bile tolerance were observed. Lactobacillus salivarius strains isolated from dental root canal manifested small differences of bile tolerance, but alike the Lactobacillus salivarius probiotic strain.Lactobacillus rhamnosus GG probiotic strain manifested the highest degree of bile tolerance for both types of bile.
