The relative expression changes of apoptosis genes in the spleen at 2 days and 6 days pi with thegtxAmutant compared with WT strain, respectively. Error bars are S.E. for each treatment group The gene expression profiles of apoptosis-related mRNA of B cell lymphoma-2 (Bcl-2), caspase-8, caspase-3, caspase-9 differed significantly (*P < 0.05, **P < 0.01, ***P < 0.001) between WT and ΔgtxA mutant groups, respectively.
