[Polio immunity in North African children hospitalized for paralytic poliomyelitis due to type 1: relative deficiency in humoral immunity compared with European children (author's transl)]. / Immunité antipoliomyélitique acquise par les enfants d'Afrique du Nord après poliomyélite paralytique à type 1. Déficience relative de l'immunité humorale comparée à celle des enfants européens.

ABSTRACT

Three points may be emphasized 1. The antibody titers in North African children are lower than previously reported for European children during the period 1950-1960. 2. In both groups of children, there is a positive correlation between the antibody titers and the age of infection (paralysis or vaccination). 3. The non polio enterovirus present in the intestine of paralyzed children at the same time as the poliovirus seem to suppress the polio immunity. This last point should be confirmed on a larger scale.
