[Seroprevalence of toxoplasmosis among women having spontaneous abortion and pregnant women following in a center of health up-town in Dakar].

A prospective survey carried on 70 women having a spontaneous abortion and 70 pregnant women was achieved in the center of health Roi Baudouin of Guediawaye (Senegal) between November 2001 to April 2002 to study the toxoplasmosis in the two groups. Anti-toxoplasmosis antibodies were searched for on all women by a technical solid-phase enzyme immunoassay. The solid-phase is a combs. The seroprevalence of the toxoplasmosis is 37.1% among women having aborted and 40% for pregnant women. The difference is not statistically significant (p = 0.729). The seroconversion is 22.8% among women having aborted and 10% for pregnant women. The difference is statistically significant (p = 0.041). The research of factors favoring the infestation, related to through food habits, pleads in favor of a contamination during childhood, essentially soil and/or eating undone meat. With regard the high percentage of not immunized women (62.9% for women having aborted and 60% for pregnant women), it is necessary to take prophylactic measures to prevent congenital toxoplasmosis.
