Although both Th17 and IgA responses have been shown to provide protection against Salmonella infection (Martinoli et al., 2007; Ko et al., 2009; Mayuzumi et al., 2010; Geddes et al., 2011; Keestra et al., 2011), it is still unclear whether both the ΔlppAB and ΔlppAB ΔmsbB mutant-induced Th17 and IgA responses in mice are directly linked to their protection against subsequent WT S. typhimurium challenge. This evidence concerns the gene CD79A and Salmonella Infections.
