Figure 2.Elimination of commensal microbe by antibiotic treatment extends host lifespan. (A–C) Colony-forming units (CFUs) of Conv flies treated with ×0.1, ×0.5, or ×1 of the antibiotic cocktail AB for 10 days (A), 30 days (B), and 50 days (C). (D–E) Survival of flies treated with ×0.1, ×0.5, or ×1 AB in Conv fly (D) and Ax fly (E). (F) Mean lifespan of flies treated with ×0.1, ×0.5, or ×1 AB. Filled dots, Conv flies; open dots, Ax flies. Different letters indicate significant differences between groups. Error bars represent the SEM.
