Despite an almost significant 1.8-fold higher level of MAP4K3 mRNA in the Boran group relative to N'Dama before infection (P = 0.0617); The N'Dama group had significantly higher expression levels of MAP4K3 at 25 dpi (1.5-fold, P = 0.0000) 29 dpi (1.6-fold, P = 0.0166) and 34 dpi (1.3-fold, P = 0.0058) relative to the Boran. This evidence concerns the gene MAP4K3 and infection.
