Project description:Probiotics may alter stress sensitivity by modulating the gut-brain axis. The heat-inactivated, enteric-colonizing Lactobacillus gasseri, CP2305 (paraprobiotic CP2305), has been shown to ameliorate psychological stress-related symptoms. This study was designed to reveal the beneficial effects of paraprobiotic CP2305 on top athletes experiencing physical and mental stresses.
Project description:Whole genome DNA microarray designed for the probiotic L. johnsonii strain NCC533 was used for comparative genomic hybridization (CGH) of L. johnsonii ATCC 33200T, L. johnsonii BL261, L. gasseri ATCC 33323T and L. iatae BL263 (CECT 7394T). In these experiments, the fluorescence ratio distributions obtained with L. iatae and L. gasseri showed characteristic inter-species profiles. The percentage of conserved L. johnsonii NCC533 genes was about 83% in the L. johnsonii strains comparisons and decreased to 51% and 47% for L. iatae and L. gasseri, respectively. These results confirmed the separate status of L. iatae from L. johnsonii at the level of species, and also that it is closer to L. johnsonii than L. gasseri.
Project description:Investigated whether EVs derived from a strain of Lactobacillus (L. gasseri BC12) that is capable of inhibiting HIV-1 infection contain proteins that differ from EVs isolated from a strain (L. crispatus BC5) that does not inhibit HIV-1 infection.
