| Outline of Final Research Achievements |
The diagnosis of malaria at regional clinics in endemic areas has mainly been performed by microscopic examination of blood smears because of its ease and rapid application. However, the blood stages of malaria parasites often difficult to differentiate morphologically. Therefore, to improve global health efforts towards malaria control, a rapid, sensitive, species-specific, and economically viable diagnostic method is needed. In the present study, we developed a single-stranded tag hybridization chromatographic printed-array strip (STH-PAS) method for the molecular diagnosis of malaria infection and evaluated its sensitivity, specificity, and clinical applicability. We presented the successful development of a STH-PAS method for detecting malaria parasites, using a primer set that targets the cytochromｂgene of the parasites. The detection sensitivity was found to be at least 100 times higher than that of agarose gel electrophoresis with ethidium bromide.
