Time-to-death analysis of intravenous Yersinia infections. (A) About 150 CFU of Y. pestis KIM5 or Y. pestis KIM5ΔyopM were delivered intravenously via tail vein injection to groups of four C57BL/6J mice each. Time to death was monitored for 14 days. Results are pooled from two independent experiments (n = 8). (B) Time-to-death analysis of intravenous Y. pseudotuberculosis infection. About 1,500 to 2,500 CFU of Y. pseudotuberculosis 32777 or Y. pseudotuberculosis 32777ΔyopM were delivered to groups of C57BL/6J mice, and survival was monitored for 21 days. Results are pooled from two or three independent experiments with 2 to 4 mice per group (n = 10 for 32777; n = 9 for 32777ΔyopM).
