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.
