TLR2 does not contribute to host defense against serotype 2 S. pneumoniae
after splenectomy. Survival (1A) and bacterial outgrowth (1B) of WT mice and TLR2KO mice. Mortality was assessed two times per day after infection with 5*105 CFU of S. pneumoniae (D39), for 1 week (8 WT versus 7 KO mice). Bacterial loads were determined 6 and 24 hours after infection with 6*105 CFU. Data of bacterial loads are expressed as scatter-plots.
