Malaria Self Test Module
Aches and pains, with fever. Glandular Fever? Malaria?
Click on one of the following:
Plasmodium falciparum?
Sorry! Have another look.
Note the enlarged infected red cells. There is a developing form
of Plasmodium exhibiting coarse granulation to the left of the field. The
numerous ring forms are much thicker than you would normally expect
to see in P. falciparum.

Plasmodium vivax?
Correct!
Did you observe the Schuffner's dots in the parasitised red cells to the left of the field?.
Also note the much thicker (signet) ring forms and the enlarged red cells, which you
would not normally expect to see in P. falciparum. Well done!

Plasmodium ovale?
Sorry! Have another look.
You obviously noticed that the parasitised red cells were enlarged.
However there is no evidence of comet-like infected red cells and
in the presence of typical "signet ring" forms as well as the developing
form to the left of the field (exhibiting granulation), this is extremely
unlikely to be a case of P.ovale.

Plasmodium malariae?
Sorry! Have another look.
Note the enlarged infected red cells. There is a developing form
of Plasmodium exhibiting coarse granulation to the left of the field. The
numerous ring forms are much thicker than you would normally expect
to see in P. malariae.

Malarial parasites not seen?
Sorry! Have another look.
There are several parasites in this field. Go back and have another look.
Try to pick out the salient features and try to identify the species.
Look for the developing form to the left of the field and the
numerous thick (signet) ring forms.
Have another look and if you are still not sure,
go back to the TEACH section.
