Effects of bacterial probiotic strains on C. elegans lifespan. (A) Lifespan of C. elegans N2 fed with lactic acid bacteria compared to worms fed with E. coli OP50. The increase in the survival rate is represented for each strain as a percentage of the survival rate of C. elegans fed on E. coli OP50 (11, 27, 34, 36, 76, 84, 89–91). (B) Negative effects of L. salivarius and L. reuteri on C. elegans lifespan. The decrease in the survival rate is represented for each strain as a percentage of the survival rate of C. elegans fed on E. coli OP50 (92). The decrease in the survival rate is represented for each strain as a percentage of the survival rate of C. elegans fed on E. coli OP50.
