Fga^+/− and Fga^+/+ mice infected with UMAA2616. P values of survival difference are indicated in all panels. — represents Fga^+/−; ----, Fga^+/+ littermate controls. (A) Fga^+/− mice and sibling control Fga^+/+ mice were infected with 2 × 10⁷ to 10⁸ CFU UMAA2616. Data were pooled from 4 independent experiments totaling 38 Fga^+/− mice and 33 Fga^+/+ mice. (B) Fga^+/− mice and sibling control Fga^+/+ mice were inoculated with 1.4 × 10⁹ CFU UMAA2616, totaling 17 Fga^+/− mice and 22 Fga^+/+ mice in 1 experiment.
