Forty-four isolates from Bangladesh and 22 from western Thailand were successfully tested for their drug susceptibility. High degrees of resistance were observed against chloroquine with geometric mean ICs of 114.25 120.5 nM, respectively, for Bangladesh and western Thailand. Most isolates from both sites were sensitive to quinine, and all were sensitive to artesunate. Many isolates were considered resistant to mefloquine, but the geometric mean IC for the Thai isolates (98.79 nM) was 1.6 times ( = 0.002) higher than that of isolates from Bangladesh (60.3 nM). The high prevalence of mefloquine resistance in Bangladesh suggests that close surveillance is necessary to delay widespread multidrug resistant problems in the area.
