Metabolic interactions between and its host.

is an obligate intracellular parasite belonging to the phylum Apicomplexa that infects all warm-blooded animals, including humans. can replicate in every nucleated host cell by orchestrating metabolic interactions to derive crucial nutrients. In this review, we summarize the current status of known metabolic interactions of with its host cell and discuss open questions and promising experimental approaches that will allow further dissection of the host-parasite interface and discovery of ways to efficiently target both tachyzoite and bradyzoite forms of , which are associated with acute and chronic infection, respectively.
