Click on one of the following:
Plasmodium falciparum?
Correct! A very good effort.
Species identification is rarely easy from thick films. The numerous ring forms in this field are very small and as you correctly indicated are of P.falciparum. We would always recommend species confirmation from a thin film, where possible.
