Gametocyte staging on Giemsa-stained smears (cytology, reference method) and on HES-stained sections (histology) from the same bone marrow biopsy sample described in this report. Leaf-shaped forms, hemi-ellipsoid forms, forms with at least one sharp extremity, and crescent forms with two rounded extremities, a concave and a convex border were counted as stage II, III, IV and V, respectively (columns II-V). A form with finely distributed pigment, but not falling into any of the previous categories, was categorized as undetermined stage (column U). Counting results appear on Table 1.
