Taxonomy: f. Plasmodidae
Animal: Plasmodium vivax 5 05.jpg
Sites: Blood
Plasmodium vivax in thin film - note parasite displaced from red cell in a versene preserved blood sample. It is best to make the smears from native blood (ie. without anti-coagulant) as anticoagulant can distort the parasites. Bizzare forms can occur depending on the strain, the humidity of the climate and hence the time of drying of the slide, use of anticoagulant, the hours through the parasite cycle, the immunity of the person and whether the person has commenced taking drugs. It is not wise to diagnose just based on observing bizarre forms and every effort should be made to look for classic forms.
