[Hemolytic disease of African newborn. Results of a survey conducted at Brazzaville (Congo)].

The authors report one study on the haemolytic disease of african newborn made in Brazzaville (Congo). As in the most of the african countries this disease is not very frequent and it is not very severe. Two cases have been found in two twins, born after the nineth pregnancy. These twins were premature and that can explain the severity of the disease. One of these twins because of his weight which was not impotent died. The immunization in the african wife seems to occur very late, after the fifth pregnancy at least.
