TLR5 and Salmonella Infections: Similar to WT Salmonella infection (Fig. 1 E, F, G, H), bacterial burden in the spleen, liver and MLN was indistinguishable between WT and TLR5−/− mice (Fig. 7 A, B, C, D), indicating that the attenuation mediated by flgM deficiency is not due to flagellin detection by TLR5.
