BAX and infection: In contrast, on days three and five post-infection, Bax expression in the Strain V cells was significantly lower than that of the control cells (p<0.01, p value were 0.008 and 0.0015 respectively), while Bcl-2 in the Strain V cells was significantly greater than that in the control cells (p<0.05, p value were 0.048 and 0.034 respectively).
