N2 - Butyricicoccus pullicaecorum and Megasphaera elsdenii inhabit the human intestine and have probiotic potential. The aim of this study was to evaluate the effects of B. pullicaecorum and M. elsdenii on the lifespan of Caenorhabditis elegans. They significantly (P < 0.05) extended the lifespan of C. elegans compared with Escherichia coli OP50, a standard food for the worm. Analysis of age-related biomarkers such as lipofuscin, body size, and locomotory activity showed that they retarded aging. They all failed to extend the lifespan of daf-12 or dbl-1 loss-of-function C. elegans mutants compared with E. coli OP50-fed worms. However, the increase in lifespan was observed in daf-16, jnk-1, pmk-1, and skn-1 mutants. Moreover, they increased the resistance of C. elegans to a human pathogen, Salmonella typhimurium. In conclusion, B. pullicaecorum and M. elsdenii extend the lifespan of C. elegans via the transforming growth factor-beta (TGF-β) pathway associated with anti-inflammatory processes in the innate immune system.
