the role of igm and igg anti-toxoplasma gondii in abortion

57 women affected by abortion or threatened abortion were investigated in view of antitoxoplasmosis antibodies by immunofluorscence. 11 women who have aborted for the first time have positive titer of polyvalent antibodies more than 1/400. 77.3% of these women have igm titer greater than 1/20. the highest percentage of abortion was in the third month of pregnancy and this is probabley related to the increase in the percentage of women who have igm titer greater than 1/20 and who were in the acute stage of the disease. the percentage of women with a positive titer of igm titer greater than 1/20 and who were in the acute stage of the disease. the percentage of women with a positive titer of igm of greater than 1/20 decreased from the third month of pregnancy. it seems that the care and follow-up of pregnant women with toxoplasmosis whether from antibody titer or from its type is of great importance. it is preferable to titrate antitoxoplasmosis antibody titers in the sera of women before pregnancy.
