Figure 1. Persistent bacterial infections reduce lifespan and reproduction.

Figure 1

(a) Survival of female flies injected with bacteria or medium. n=90 flies. Symbols indicate mean. Bars indicate 95% confidence intervals. p<0.0001 when comparing S. typhimurium- or S. marcescens- or B. cenocepacia-injected flies to E. coli- or medium-injected flies by logrank test.

(b) Bacterial growth in individual female flies. n=5 flies. The geometric mean and 95% confidence intervals are indicated.

(c) Average eggs laid per female fly injected with bacteria or medium or left untouched. n=18. The geometric mean and 95% confidence intervals are indicated. Significance was determined by two-tailed unpaired t-test. p=.043 for E. coli- vs. medium-injected on day 10. See Supplemental Figure 1 for raw data and full time course. Note: There were no living flies on day 10 post-injection with B. cenocepacia or S. marcescens.
