Limited polymorphism in the dihydropteroate synthetase gene (dhps) of Plasmodium vivax isolates from Thailand.
The dhps sequences of 55 Plasmodium vivax isolates (39 from Thailand and 16 from elsewhere) revealed mutant Pvdhps at codons 383 and/or 553 (A --> G) in 33 isolates, all from Thailand. Mutations of Pvdhps and Pvdhfr were correlated. Multiple mutations were associated with high-grade sulfadoxine-pyrimethamine resistance.
متن کاملgenetic diversity of dihydropteroate synthetase gene (dhps) of plasmodium vivax in hormozgan province, iran
background: the present study was formulated in order to determine polymorphism of dihydropteroate synthetase gene (dhps) of plasmodium vivax (p . vivax ) in hormozgan province, southern iran and mutations at codons 382, 383, 512, 553, and 585 associated with resistance of p. vivax to sulfadoxine. method : one-hundred eighteen isolates of p. vivax were prepared within 2007-2008 to determine di...
متن کاملLimited Polymorphism of the Kelch Propeller Domain in Plasmodium malariae and P. ovale Isolates from Thailand
Artemisinin resistance in Plasmodium falciparum, the agent of severe malaria, is currently a major obstacle to malaria control in Southeast Asia. A gene named "kelch13" has been associated with artemisinin resistance in P. falciparum The orthologue of the kelch gene in P. vivax was identified and a small number of mutations were found in previous studies. The kelch orthologues in the other two ...
متن کاملdna sequence polymorphism of the lactate dehydrogenase gene¬from iranian plasmodium vivax and plasmodium falcipa¬rum isolates
background: parasite lactate dehydrogenase ( p ldh) is extensively employed as malaria rapid diagnostic tests (rdts). moreover, it is a well-known drug target candidate. however, the genetic diversity of this gene might influence performance of rdt kits and its drug target candidacy. this study aimed to determine polymorphism of p ldh gene from iranian isolates of p. vivax and p. falciparum. m...
متن کاملChange in mutation patterns of Plasmodium vivax dihydrofolate reductase (Pvdhfr) and dihydropteroate synthase (Pvdhps) in P. vivax isolates from malaria endemic areas of Thailand.
Malaria is the most important public health problem in several countries. In Thailand, co-infections of Plasmodium vivax and Plasmodium falciparum are common. We examined the prevalence and patterns of mutations in P. vivax dihydrofolate reductase (Pvdhfr) and P. vivax dihydropteroate synthase (Pvdhps) in 103 blood samples collected from patients with P. vivax infection who had attended the mal...
