Disseminated toxoplasmosis: an atypical presentation in an immunocompetent patient.

Acute acquired toxoplasmosis is considered a self-limited mononucleosis-like disease that rarely requires treatment. We report an unusual severe case of disseminated toxoplasmosis complicated with meningitis and pneumonia in a previously 41-year-old healthy Brazilian man. Toxoplasmosis should be included in the differential diagnosis of acute febrile diseases due to the non-specific clinical symptoms and the possibility of severe outcome.

Seroprevalence of infection with Toxoplasma gondii in indigenous Brazilian populations.

The prevalence of Toxoplasma gondii in indigenous Brazilian tribes with different degrees of acculturation was studied in the Enawenê-Nawê, an isolated tribe, in the state of Mato Grosso, the Waiãpi, with intermittent non-Indian contacts, in the state of Amapa, and the Tiriyó, with constant non-Indian contacts, in the state of Para. An IgG-enzyme-linked immunosorbent assay (IgG-ELISA) or an IgG/IgM-indirect immunofluorescence antibody (IFA) assay were performed for the detection of antibodies to T. gondii in 2000-2001.
