Whole-Genome Sequencing of Lactobacillus Species from Two Commercial Probiotic Products.

Eight Lactobacillus strains, each intrinsically resistant to an antibiotic, were isolated from two commercial probiotic products. Whole-genome sequencing identified two efflux transporters, a multidrug and extrusion protein (MATE) efflux transporter, and LmrCD, which may contribute to their intrinsic antibiotic resistance and may therefore facilitate their survival in the intestinal microbiota following antibiotic therapy.
