Malaria Self Test Module
Army personnel, recently returned from peace keeping in Somalia.
Click on one of the following:
Plasmodium falciparum?
Sorry. Take another look.
The ring form in the centre of the field is much bigger and thicker
than would normally be expected in falciparum. Note the size of the
infected red cell, even though this may be somewhat confusing due to
the variation in cell size amongst the non-infected red cells.
Also look at the shape of the infected red cell and note the patient history.

Plasmodium vivax?
Sorry! A good try, but take another look.
You obviously noted that the infected red cell was enlarged but take
a good look at the shape of the infected red cell and note the history.

Plasmodium ovale?
Correct! Very well done.
Not an easy diagnosis from just one parasite.
Did you note that the infected red cell was enlarged? This is a little
confused by the variation in size of the non infected red cells. The
ovoid shape of the infected red cell, together with the history helps.
The chromatin dot of the parasite appears to be inside the ring; this
is a fairly uncommon feature of P.ovale.

Plasmodium malariae?
Sorry! Take another look.
Note the size of the infected red cell, even though this may
be somewhat confusing due to the variation in cell size amongst the
non-infected red cells. Also look at the shape of the infected
red cell and note the patient history.

Malarial parasites not seen?
Sorry! Try again.
There is a large ring form in the centre of the field.
Take another look after first refreshing your memory by going back
to the Diagnosis section. Note the patient history and the size of
the infected red cell.
