Toxoplasmosis: Causes
(Professional Guide to Diseases (Eighth Edition))

T. gondii exists in trophozoite forms in the acute stages of infection and in cystic forms (tissue cysts and oocysts) in the latent stages. In addition to possible fecal-oral transmission from infected cats, ingestion of tissue cysts in raw or uncooked meat (heating, drying, or freezing destroys these cysts) can also transmit toxoplasmosis. However, toxoplasmosis also occurs in vegetarians who aren't exposed to cats, so other means of transmission may exist. Congenital toxoplasmosis follows transplacental transmission from a chronically infected mother or one who acquired toxoplasmosis shortly before or during pregnancy.

Toxoplasmosis: Causes
(Handbook of Diseases)

T. gondii existsin trophozoite forms in the acute stages of infection and in cystic forms (tissue cysts and oocysts) in the latent stages. Ingestion of tissue cysts in raw or undercooked meat (heating, drying, or freezing destroys these cysts) or fecal-oral contamination from infected cats transmits toxoplasmosis.

Congenital toxoplasmosis follows transplacental transmission from a chronically infected mother or one who acquired toxoplasmosis shortly before or during pregnancy.

Toxoplasmosis: Toxoplasmosis - pathophysiology
(The 5-Minute Pediatric Consult)

• Toxoplasmosis is acquired by the ingestion of oocysts or intact viable tissue cysts in inadequately cooked meat.
• After ingestion, the oocysts and cysts are disrupted by the digestive process, and viable infective organisms cross the GI lining. Hematologic spread leads to infection of multiple organs, most notably the heart, skeletal muscle, and the brain. There, slowly growing or dormant cysts remain for the patient’s lifetime.
• Congenital toxoplasmosis generally occurs during a primary maternal infection. An exception may be when the pregnant woman is severely immunocompromised; congenital infection has occurred in children of HIV-infected women with latent toxoplasmosis infection.
• Primary infection in the 1st trimester is associated with a higher incidence of symptomatic congenital disease, although most congenital infections occur late in pregnancy, and affected neonates have subclinical infection at birth. Overall, 30–40% of infants born to mothers with primary infection during pregnancy will be congenitally infected.
