Different mutation patterns of atovaquone resistance to Plasmodium falciparum in vitro and in vivo: rapid detection of codon 268 polymorphisms in the cytochrome b as potential in vivo resistance marker.

Abstract excerpt

BACKGROUND: Resistance of Plasmodium falciparum to atovaquone in vitro and in vivo has been associated to mutations in the parasite cytochrome b gene. METHODS: Cultures were sequentially subjected to increasing doses of atovaquone alone or in combination with cycloguanil and the cytochrome b gene was sequenced. Additionally, we investigated the parasite cytochrome b gene of a patient returning from Mali with...
