Comparative analysis of IgG and IgG subclasses against Plasmodium falciparum MSP-1 in children from five contrasting bioecological zones of Cameroon.

Background: Studies reporting the natural immune responses against malaria in children from different geographical settings in endemic areas are not readily available. This study was aimed at comparing the immune responses against Plasmodium falciparum MSP-1 antigen in children from five contrasting bioecological zones in Cameroon.

Methods: In a cross-sectional survey, children between 2 and 15 years, were enrolled from five ecological strata including the south Cameroonian equatorial forest, sudano-sahelian, high inland plateau, high western plateau, and the coastal strata.
