Gametocytes of Hemoproteus spp. are relatively small; the erythroid origin of the host cell
remains apparent. The organisms have a textured appearance and contain scattered
pigment granules; they may nearly encircle the RBC's nucleus.||
Gametocytes of Leukocytozoon spp. are much larger; the nature of the host cell is obscured.
Both elongated (sail-like) and compact spherical forms (inset) may be seen
in the same smear.|
Among the samples received in this laboratory, these two parasites are seen most commonly in blood from
raptors, in which symptomless infection seems the rule.|
