The role of commensal microbes in the lifespan of Drosophila melanogaster

Figure 3. Lifespan extension effect of the elimination of commensal microbes differs among laboratory fly strains. (A) The total number of CFUs from 1-week-old flies in plate count agar (PCA) media. (B) Survival curve of laboratory wild-type w1118, Oregon-R, and Canton-S strains with the elimination of microbes. Solid lines, Conv flies; dashed lines, Ax flies. (C) Mean lifespan of laboratory wild-type w1118, Oregon-R, and Canton-S strains following the elimination of microbes. Filled dots, Conv flies; open dots, Ax flies. Asterisks indicate significant differences between Conv flies and Ax flies (log-rank test, *p < 0.05, ***p < 0.0001). Error bars represent the SEM.
