This paradox can be interpreted as the evolution of a plastic strategy of feeding behavior in this field population of An. gambiae because of the greater accessibility of readily available, although less-preferred, hosts.
While analyzing wild mosquitoes caught in Paju, South Korea, we identified one egg-laying hybrid female between Anopheles kleini and Anopheles sinensis.
This study significantly increases the number of genetic markers available for An. albimanus and provides useful tools for population genetics and genetic mapping studies in this important malaria vector.
We investigated the relationship between rosetting and clinical malaria in 209 Malian children enrolled in a case-control study of severe malaria.
Both regimens were well tolerated. AMQ clears parasitemia and reduces gametocyte carriage more rapidly and causes lesser fall in hematocrit than MQ, but both regimens are effective treatment of uncomplicated P. falciparum malaria in Nigerian children.
This multi-center, randomized, parallel-group, double-blind, double-dummy study compared the efficacy and safety of chlorproguanil–dapsone–artesunate (CDA) and chlorproguanil–dapsone (CPG–DDS) in the treatment of falciparum malaria in Africa (Burkina Faso, Ghana, Mali, Nigeria).
Here we describe high rates of P. vivax recurrence (26–40% 180 days after treatment) in two cohorts of rural Amazonians exposed to low levels of malaria transmission after a vivax malaria episode treated with chloroquine-primaquine.
The results suggest propagation of mixed infections by multiple inocula, not super-infection, implying decade-long opportunity for outcrossing in these mixed infections.
Findings support the use of small scale mapping and targeted vector control in urban malaria control programs in Africa.
Informal sources of care may lead to ineffective use of antimalarial drugs. A survey conducted in Malawi estimated the frequency of use of informal and formal services, medications, and household costs.
