Answer

Tissue cysts form as early as 7 days after infection and remain for the lifespan of the host. The tissue cysts are up to 60μm in diameter, each containing up to 60,000 organisms. They produce little or no inflammatory response but cause recrudescent disease in immunocompromised patients or retinochoroiditis in congenitally infected older children.
