| Outline of Final Research Achievements |
The IgG Ab level to AAPP was evaluated before, during and after the rainy season in cohorts of residents in Sumba. IgG responses to malaria antigens were also examined. A total of 2,617 samples of the sera were analyzed for the Ab levels in comparison with malaria incidence. In the residents during the rainy season, IgG response against AAPP was significantly increased, and this response was significantly higher in the cohort of individuals infected with P. falciparum than those of parasite-free population. Throughout the seasons, IgG levels toward anti-malaria antigens from P. falciparum were significantly increased in the cohort of individuals infected with P. falciparum, but those against P. vivax antigens were relatively weak. Our result demonstrates that anti-AAPP IgG response reflects P. falciparum infection during rainy season in response to higher mosquito exposure; hence this biomarker can be a powerful tool for the evaluation of exposure to malaria vector mosquitoes.
