Artemisinin resistance in Plasmodium falciparum malaria.

ABSTRACT:

Background

Artemisinin-based combination therapies are the recommended first-line treatments of falciparum malaria in all countries with endemic disease. There are recent concerns that the efficacy of such therapies has declined on the Thai-Cambodian border, historically a site of emerging antimalarial-drug resistance.

Methods

We assessed in vitro and in vivo Plasmodium
