The role of commensal microbes in the lifespan of Drosophila melanogaster

Figure 1. Elimination of commensal microbes by egg bleaching extends host lifespan. (A) Survival of first (1G), second (2G), and third (3G) generations of Ax flies from bleached eggs. (B) Mean lifespan of Conv fly and 1G, 2G, and 3G of Ax flies from bleached eggs. Filled dot, Conv flies; open dots, Ax flies. (C) Survival of Ax flies treated with feces from 10-day-old Conv flies. (D) Mean lifespan of Ax flies treated with feces from 10-day-old Conv flies. Black dot, Conv flies; white dot, Ax flies fed feces from Ax flies; gray dot, Ax flies fed feces from Conv (Ax + FecesConv) flies. Different letters indicate significant differences between groups. Error bars represent the SEM.
