Schistosoma haematobium infection modulates Plasmodium falciparum parasite density and antimalarial antibody responses.

Aims: Schistosomiasis and malaria are endemic in sub-Saharan Africa where Schistosoma haematobium (Sh) and Plasmodium falciparum (Pf) coinfections are thus frequent. We explored the effect of Sh infection on antibody responses directed to Pf merozoite antigens and on malaria susceptibility in Beninese children.

Methods And Results: A total of 268 children were followed during a malaria transmission season.
