Summary
Air-dried blood smears and erythrocyte suspension from patients infected with Plasmodium falciparum, stained under optimal conditions with acridine orange, permit easy detection of plasmodia with fluorescence microscopy together with a clear cytochemical colour differentiation of nuclear DNA (green or green-yellow) and cytoplasmic RNA (orange-red fluorescence). Judging from fluorescence characteristics of nuclei (DNase sensitive and RNase resistant green or green-yellow), the plasmodial DNA appears to be double-stranded.
