Toxoplasma gondii is a universally-distributed pathogen that infects over 1 billion people worldwide. Host resistance to this protozoan parasite depends on the potent production of IL-12 and IFN-γ. Although Toll-like receptor 11 (TLR11) plays a major role in controlling Th1 immunity to this pathogen in mice, this innate immune receptor is not functional in humans, and the mechanisms of TLR11-independent sensing of T. gondii remain elusive. Here, we show that both mucosal innate and adaptive immune responses to T. gondii rely on the indirect stimulation of dendritic cells by normal gut microflora. We identify a novel function for commensal bacteria in which they provide an immunostimulatory effect on dendritic cells during parasitic infection. Our results reveal that indirect immunostimulation by gut commensals provides protection against T. gondii in the absence of TLR11.
