Fig. 5.

Zygotes (a, d, g), growing ookinetes (b, e, h) and mature ookinetes (c, f, i) of Haemoproteus minutus (hTURDUS2, a–c), Haemoproteus pallidus (hSFC3, d–f) and Haemoproteus pallidus (hPFC1, g–i) during development in vitro. Note that all these parasites do not produce any outgrowths during ookinete development, and their ookinetes do not contain vacuoles (c, d) or are only slightly vacuolated (f); these parasites appeared in one well-supported sub-clade b2 in the phylogenetic tree (Fig. 1). Long simple arrows, nuclei of parasites; short simple arrows, vacuoles; simple arrowheads, pigment granules. Methanol-fixed and Giemsa-stained thin blood films. Scale-bar: 10 µm
