Plasmodium berghei infection in pregnant rats: effects on antibody response and course of infection in offspring

Abstract

The effects of primary, patent Plasmodium berghei infection in Sprague-Dawley rats during pregnancy upon the course of infection and the humoral antibody response to malaria in their offspring were examined. Malaria specific antibody determined by an indirect fluorescent antibody test correlated well with the parasitologic profiles of each experimental group. Utilization of foster mother groups indicated passive transfer of protective antibody through milk. Evidence for in utero sensitization by soluble malaria antigens was shown by an anamnestic-like antibody response during subsequent infection of offspring from infected mothers.
