Toxoplasma gondii (Toxoplasmosis)
Summary of Toxoplasma gondii (Toxoplasmosis)
Toxoplasma gondii is an obligate intracellular, parasitic protozoan that causes the disease toxoplasmosis. Found worldwide, T. gondii is capable of infecting virtually all warm-blooded animals, but felids such as domestic cats are the only known definitive hosts in which the parasite can undergo sexual reproduction. Cleaning cat litter boxes is a potential route of infection. Transmission is by ingesting cysts in undercooked meat. It is part of ToRCHeS infections and if transmission occurs in a pregnant woman, the fetus can acquire congenital toxoplasmosis consisting of the triad of chorioretinitis, hydrocephalus, and intracranial calcifications.
