Toxoplasma gondii is an obligate intracellular parasite capable of infecting mammals, birds, reptiles, and fish. T. gondii only undergoes sexual reproduction in a feline host. In all other organisms the parasite reproduces asexually, either as fast growing tachyzoites or slow growing bradyzoites. Bradyzoites form latent cysts inside the host cell that can lay dormant for years and convert back to tachyzoites when the host’s immune system becomes weakened. Tachyzoites rapidly replicate in the host cell, eventually causing it to lyse. While extracellular, tachyzoites repress their own translation by phosphorylating the eukaryotic initiation factor eIF2α and form microscopically visible aggregates of …
