Plasmodium falciparum?
Sorry. Take another look at this film.
There is only one ring form present in this field
which normally could make species identification a little risky.
However, in this case the size of the infected red cell, together
with the size and thickness of the ring would make a diagnosis
of P. falciparum very improbable.

Plasmodium vivax?
Correct! Good effort!
Even with only one parasite in this field you were able to
observe that the infected red cell was enlarged and the size and
shape of the typical "signet" ring form was indeed vivax. Well done.

Plasmodium ovale?
Sorry! Take another look.
You obviously noted that the infected red cell was enlarged. Take
another look, noting especially the shape of the infected red cell,
the shape and size of the parasite and the patient history.
Now armed with those clues, have another look.

Plasmodium malariae?
Sorry! Have another look.
There is only one ring form present in this field which
normally could make species identification a little risky.
However, in this case the size of the infected red cell,
together with the size and thickness of the ring would make a
diagnosis of P. malariae very improbable.
Try again and pay particular attention to the patient history.

Malarial parasites not seen?
Sorry! Try again.
There is a very distinctive ring form in this field.
Take another look noting the size and shape of the infected
red cell, the size of the ring form and the patient history.
Refresh your memory by referring to the
Diagnosis and Teach pages then try again.
