[Serological studies of a pygmy population in Cameroon]

Serological studies made in a community of 106 pygmies led to 60% positive reactions with parasitic antigens, mainly of nematodes and trematodes. IgG and IgM levels are increased (about two times and four times the levels found in a normal population). These results prove the importance of these infestations by human or animal parasites in a tropical forest population.
