She is planning to get pregnant soon. What are the risks for her and her baby? ANSWER: Up to 25% of Canadians are IgG-positive for Toxoplasma due to past exposure. Immunoglobulin M (IgM) titres indicate current infection. Toxoplasma gondii is an obligate intracellular protozoan that has several forms during its life cycle: oocyte, tachyzoite, and cyst.
