This document discusses Plasmodium and Toxoplasma, which cause malaria and toxoplasmosis respectively. It covers their life cycles, transmission, pathogenesis, clinical findings, and laboratory diagnosis. Plasmodium is transmitted by mosquitoes and causes malaria, while Toxoplasma is transmitted through contact with cat feces or undercooked meat and causes toxoplasmosis including congenital infection. Both involve asymptomatic infection in healthy individuals but can cause severe disease in immunocompromised patients.
