Investigation into the immunoglobulin class responsible for the polar staining of Toxoplasma gondii in the fluorescent antibody test.
Bipolar staining of the trophozoites of Toxoplasma gondii has been observed with a number of sera from patients. It has been demonstrated that the serum factors involved are IgM. The majority of sera demonstrating this phenomenon had raised nonspecific IgM levels.
