FIG 4 .

Impact of microbiota reassociation on fly development on the no-thiamine diet. (A) Proportion of gnotobiotic eggs that emerged as adults when reassociated with microbiota members. Significant differences from Cox proportional hazards (CoxPH) modeling are depicted as letter superscripts next to the reassociations in the keys. The survival to adulthood is significantly higher in the A. pomorum-monoassociated gnotobiotic flies (P < 0.001). (C) Proportion of gnotobiotic eggs that emerged as adults when associated with wild-type and mutant A. pasteurianus. (B and D) Developmental progression as the time to adult emergence in the microbiota and A. pasteurianus associations, respectively. No flies developed when associated with the mutant (B). Values are means ± SEM.
