The behaviour of antitoxoplasmic antibodies during pregnancy

The authors have studied the antitoxoplasmic antibody behaviour longitudinally in a sample of pregnant women and in one of nonpregnant women, all of them not affected by an active infectious process. No significant difference has been found between the various pregnancy trimesters. The antibody titre in non-pregnant women has proved significantly higher than in the pregnant ones. In a sample of 131 women it has been found that the antibody titre before pregnancy is significantly higher than the one present in the first trimester. The authors conclude that during pregnancy the antitoxoplasmic antibody level is lower as compared to the one of non-pregnant women; and this phenomenon implies various hypothese calling for further discussion.
