Mefloquine resistance in Plasmodium falciparum and increased pfmdr1 gene copy number
BACKGROUND The borders of Thailand harbour the world's most multidrug resistant Plasmodium falciparum parasites. In 1984 mefloquine was introduced as treatment for uncomplicated falciparum malaria,… Expand
Maternal antibodies block malaria
Women are at increased risk from malaria during pregnancy, and, for unknown reasons, this risk is greatest during the first pregnancy. Plasmodium falciparum, the most virulent of the four malaria… Expand

ABSTRACT On the western border of Thailand, Plasmodium falciparum has become resistant to almost all antimalarial agents. The molecular basis of resistance in these parasite populations has not been… Expand
Changes in the Treatment Responses to Artesunate-Mefloquine on the Northwestern Border of Thailand during 13 Years of Continuous Deployment
Background Artemisinin combination treatments (ACT) are recommended as first line treatment for falciparum malaria throughout the malaria affected world. We reviewed the efficacy of a 3-day regimen… Expand
