TLR4 and clostridium difficile infection: The TT genotype of the TLR2 rs3804099 polymorphism was more often noted in those with CDI than in those without CDI (64.5% vs. 46.1%; P = 0.046), but no correlation was present between other TLR2 (rs1898830 and rs7656411) or TLR4 (rs10983755 and rs1927914) polymorphisms and CDI (Table 1).
