However, we observed an increase in IgA+ cells in the large intestine of both ΔdblGATA-1 mice and BALB/c mice post-infection (Fig. 3a–e) (Two-way ANOVA showed a significant effect of infection F (2,42) = 63.79, p < 0.0001 with a post-hoc Bonferonni test showing a significant effect at d21 (p < 0.0001, BALB/c and ΔdblGATA-1 mice) and d35 (p < 0.05 ΔdblGATA-1 mice; p = NS BALB/c). This evidence concerns the gene CD79A and infection.
