"Tachyzoite" Natural Recordings by Native Speakers
A tachyzoite is a parasitic stage of a protozoan, particularly Toxoplasma gondii, a parasite that infects humans and other mammals.
The tachyzoite is one of the two main stages of the parasite's life cycle, the other being the bradyzoite. Tachyzoites are the rapidly multiplying form of the parasite, and are responsible for causing the acute symptoms of toxoplasmosis, such as fever, headache, and swollen lymph nodes.
