FIG 7.

Kaplan-Meier plot of survival after infection with E. coli expressing BadA HN23 hybrid 3. G. mellonella larvae were infected with E. coli BadA HN23 hybrid 3 (resuspended in 10 μl of PBS) at 1.0 × 10⁷ per larva (n = 30). Two control groups were included: uninfected G. mellonella larvae (n = 30) inoculated with sterile PBS (injection control) and E. coli (empty vector control; 1.0 × 10⁷)-infected G. mellonella larvae (n = 30). p.i. [d], days postinfection. *, significant difference in larva survival between vector control and BadA HN23 hybrid 3 (P < 0.01). Data represent the cumulative results of three independent experiments.
