Fig. 1From: A dual colour fluorescence in situ hybridization (FISH) assay for identifying the zoonotic malaria parasite Plasmodium knowlesi with a potential application for the specific diagnosis of knowlesi malaria in peripheral-level laboratories of Southeast AsiaFluorescence observed in the PK-FISH assay with the P. knowlesi-specific probe (green) and the Plasmodium genus-specific probe (orange) on monkey blood smears containing P. knowlesi. Dual colour fluorescence seen in a single microscope field at ×1000 magnification using the two different filters is shown in each set of paired photographs. The four sets of paired photographs are from four different fields (i) - (iv). Scale-bars: 5 μmBack to article page
