Figure 7. A Bacterial Factor Is Required for Intoxication of the Fly by Cholera Toxin.

Figure 7

Fractional survival over time of wild-type flies fed LB alone, wild-type V. cholerae, or a V. choleraeΔctxB mutant (ctxB) either with or without 10 μg/ml purified cholera toxin. Log-rank test analysis demonstrated a statistically significant difference in the survival of wild-type flies fed a V. cholerae ΔctxB mutant (ctxB) alone and those fed a V. cholerae ΔctxB mutant (ctxB) combined with purified cholera toxin (p < 0.0001).
