Dondorp %A Mallika Imwong %J PLOS ONE %D 2014 %I Public Library of Science (PLoS) %R 10.1371/journal.pone.0093942 %X The dihydropteroate synthase (dhps) genes of 44 P. malariae strains from four Asian countries were isolated. Only a limited number of polymorphisms were observed. Comparison with homologous mutations in other Plasmodium species showed that these polymorphisms are unlikely to be associated with sulfadoxine resistance. %U http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0093942
