Primary T. gondii infection is asymptomatic in most patients including pregnant women. Absence of anti-Toxoplasma IgG antibody in pregnant women may result into congenital toxoplasmosis in the fetuses provided the infection which is acquired during pregnancy. The prevalence is supported to be 0.05% of live births. The various abnormalities include mental retardation, seizures, blindness, deafness and stillbirth including abortion. Therefore, it is important to know the time of infection acquired. Serologic tests are used to diagnose primary infection in pregnant women. IgG antibody arise within 1-2 weeks after infection and persist lifelong. Detection of Toxoplasma specific IgM antibody indicates recent infection, however, the exact time can not be determined. Measurement of IgG avidity has been used to distinguish the recent infection from the past one. Generally, during pregnancy, it is important to avoid eating raw or undercooked meat, avoid travels abroad especially in France, the USA and Canada, and maintain personal hygiene.}, pages = {31--39}, title = {妊婦におけるトキソプラズマ症検査の意義}, year = {2009}, yomi = {イシヤマ, サトコ and アシタカ, ヨシヒコ} }
