Abstract
In mice infected with an avirulent strain of Toxoplasma gondii, circulating Toxoplasma antigens were detectable in the sera during weeks 1 to 3 of infection by a simple agglutination test that uses latex particles coated with anti-Toxoplasma antibodies. An infection in athymic nude mice resulted in high agglutination titers in the anti-Toxoplasma antibody-coated latex particle test and the absence of anti-Toxoplasma antibodies in sera during the acute phase, suggesting that the detection of circulating Toxoplasma antigens is a good tool for the diagnosis of acute toxoplasmosis, especially in severely immunocompromised hosts.
