Morphological features of gametocytes, which are used for identification of Haemoproteus species parasitizing Gruiformes birds. Macrogametocytes (a, c–h) and microgametocyte (b) of Haemoproteus balearicae (a, b), H. gallinulae (c, d), H. antigonis (e), H. porzanae (f–h). Note the slender form of H. balearicae gametocytes (a, b) and the presence of dumbbell-shaped growing gametocytes in H. porzanae (f, g). Long simple arrows—host cell nuclei. Short simple arrows—parasite nuclei. Simple arrowheads—pigment granules. Simple wide long arrows—spaces between gametocytes and envelope of infected erythrocytes.
