Taoxoplasma Parasites (IMAGE) Indiana University School of Medicine Caption The parasite responsible for toxoplasmosis requires a stress response system that helps it survive the move to infect new cells, Indiana University School of Medicine scientists have reported, a discovery that could lead to new treatments to control the disease. The image shows two Toxoplasma parasites outside of their host cell. The trails are proteins left behind when the parasite glides on the substrate used during the imaging process.
