Selection and use of lactic acid bacteria preventing bone loss in mammals
The present invention comprises a method for selecting lactic acid bacterial strains effective for preventing bone loss in humans and strains that have been selected according to the presented method. The selection method is based on the strain's capability of reestablishing an altered microbial community to normal and/or harboring at least one of four specific SNPs.
1. A method for the treatment or prevention of bone loss, comprising administering to an individual in need thereof a lactic acid bacterial strain comprising a nucleic acid sequence having at least 95% identity to the nucleic acid sequence of the genome of L. reuteri JCM 1112 (SEQ ID NO: 1), and harboring an identical nucleotide relative to the genome of L. reuteri JCM 1112 (SEQ ID NO: 1) in at least one of the following four positions: C in base pair 271 391, G in base pair 453 538, G in base pair 529 228, and C in base pair 599 338, wherein the lactic acid bacterial strain is L. reuteri ATCC PTA 6475.
