Plasmodium falciparum: mutation pattern in the dihydrofolate reductase-thymidylate synthase genes of Vietnamese isolates, a novel mutation, and coexistence of two clones in a Thai patient.

Abstract

Pyrimethamine and cycloguanil resistance of Plasmodium falciparum has been linked to mutations in the dihydrofolate reductase (dhfr) portion of the dhfr-ts gene. In this paper, the DNA sequence of the dhfr-ts gene of 50 isolates from Vietnam and 2 clones (T9/94 and T9/96) isolated from a malaria patient from Thailand have been analyzed. A comparison between… (More)
