Which form of Toxoplasma gondii is produced in infected humans?

Explanation:
Humans harbor a tissue cyst form called bradyzoites after infection. During the initial acute phase, the parasite replicates as tachyzoites and spreads through tissues, but over time it differentiates into bradyzoites that reside inside tissue cysts, especially in brain and muscle. These cysts can persist for life and may reactivate if immunity weakens. The other stages mentioned—oocysts (environmental form produced by cats) and the sexual stages macrogametes and sporoblasts (also occurring in cats during the parasite’s sexual cycle)—do not form inside humans. Therefore, the form produced and maintained in infected humans is bradyzoites.
