Effects of parasitic infections in pregnant women.

ABSTRACT

This review focuses on the parasitic diseases which occur frequently in the tropics and which affect pregnant women. Clinical disease of the mother during pregnancy, vertical transmission of parasites and transplacental passage of soluble parasitic antigens are discussed in relation to their immunopathological significance for the fetus. The incidences of congenital malaria, African trypanosomiasis and Chagas' disease are reviewed, together with vertical transmission of filarial infection, involvement of the female genital tract in schistosomiasis, and fulminant colitis due to Entamoeba histolytica infection during pregnancy.
