Typical DF haemozoin and non-haemozoin objects. Typical objects of interest. A: Haemozoin objects, 100× BF thumbnails (top row) and the corresponding 50× DF thumbnails (second row) showing the haemozoin within the parasites. (1–4) are rings, (5) is a gametocyte. Note in (4) that one ring/troph has visible haemozoin, while the other ring does not. B: Typical non-haemozoin objects, DF thumbnails. The larger rings are cell wall information due to haemoglobin scattering.
