Moreover as well as changes post-infection, an unanticipated significant effect of genotype was observed with significantly higher numbers of IgA+ plasma cells in the ΔdblGATA-1 mice (F (1,42) = 17.51, p = 0.0001 with a post-hoc Bonferonni test showing a significant effect (p < 0.0001) at d21 post-infection). The gene discussed is CD79A; the disease is infection.
