Infectivity of falciparum malaria patients for anopheline mosquitoes before and after chloroquine treatment

Abstract

The infectivity of 25 falciparum malaria patients for Anopheles balabacensis and Anopheles minimus, before and after chloroquine therapy, was studied in central Thailand. The proportion of patients infective for these mosquitoes was not affected by the administration of chloroquine, however, an elevation was observed in the median values for the numbers of oocysts on the guts of the A. balabacensis, but not the A. minimus, fed on infective patients after initiation of treatment.
