Taxonomy: f. Plasmodidae
Animal: Plasmodium falciparum 4 11.jpg
Sites: Blood
Plasmodium falciparum in thick film with trophozites. (Not a very well prepared or stained film). The background ideally should be clear, mottled pale-grey. When the red cells are lysed, the parasites will be distorted so ring forms become like commas or exclamation marks. If the background is too pale, the parasites will be unstained but if very dark, the parasite will also not be able to be seen. If not enough time is given for drying both leucocytes and the parasites are very distorted. The texture of the thick film depends on the method, quality of stain, depth of staining and on the state of the blood.
