Molecular epidemiology of malaria in Cameroon. XXVII. Clinical and parasitological response to sulfadoxine-pyrimethamine treatment and Plasmodium falciparum dihydrofolate reductase and dihydropteroate synthase alleles in Cameroonian children.

Abstract excerpt

The rapidly changing epidemiology of antifolate-resistant Plasmodium falciparum in Africa requires monitoring. The present study was designed to assess the degree of association between the clinical and parasitological response to sulfadoxine-pyrimethamine and allelic combinations of dihydrofolate reductase (dhfr) and dihydropteroate synthase (dhps) genes. Of 357 children who completed the 14-day follow-up, an...
