From: Attenuated vaccine PmCQ2Δ4555–4580 effectively protects mice against Pasteurella multocida infection
The virulence of PmCQ2Δ4555–4580. A: Survival rates of mice. B-D: Bacterial burdens in the lungs (B), liver (C) and spleen (D) of mice at 4, and 8 h postinfection. A was pooled from three independent experiments with 10 replicates per group, and determined by Log-rank (Mantel-Cox) test. B-D were pooled from two independent experiments with 7–10 replicates per group, and were analyzed by two-way ANOVA, and expressed as means ± SD. **P < 0.01, ***P < 0.001
