CD40LG and congenital toxoplasmosis: Since 2 CT cases could be observed only based on IgG immunoblot results (qualitative PlateliaTM TOXO IgM cord blood results being negative and IgM immunoblotting could not be performed), the congenital toxoplasmosis rate was 0.2%, corresponding to 2/835 live births (95% CI [0.0003; 0.086]), i.e., a ratio of 2.39 per 1,000 live births, among the initial group of 974 women with known toxoplasmosis serological status; knowing that 19 births were twins, 163 deliveries remained unrecorded, for 816 women (i.e., 835–19) among the whole study group of 979 women.
