Toxoplasmosis: Researchers identify protein that evolved alongside infection machinery
Toxoplasmosis is an infectious disease found worldwide‚ caused by the single-celled parasite Toxoplasma gondii. In humans‚ infection poses a particular risk to pregnant women‚ as it can lead to birth defects. Like the closely related malaria pathogen—Plasmodium falciparum—and other related species‚ T. gondii possesses special organelles‚ so-called rhoptries and micronemes‚ for infecting the host cell.
