FIG. 1 in Fine structure of gametocytes in five species of Haemoproteus (Haemosporidia) from geckos and agamid lizards

FIG. 1. — Haemoproteus edomensis in erythrocytes of Agama stellio; A, macrogametocyte with dense ribosomal contents, showing large inclusion with phagosomal residues, mitochondria and a vacuole; B, macrogametocyte (with dense ribosomal contents) showing the compact nucleus, two adjacent golgi-like tubular structures, inclusions, one containing membranous vesicular residue (e) and the other electron dense deposit (ee); C, macrogametocyte with tail-like ending (arrows), containing a compact nucleus with large nucleolus, an inclusion with phagosomal residue, mitochondria and "trapezoid" organelle; D, higher magnification view for details of the boundary membranes; E, detailed view of boundary membrane accompanied beneath by er extension; F, higher magnified view of a macrogametocyte, with compact nucleus, containing a conspicuous nucleolus, next to which can be seen an aggregate of granular matrix (arrow head); the cytoplasm contains bundles of er, a "trapezoid" and residue inclusions; G, unit membrane-bound food vacuole; H, detail from a juvenile gametocyte, showing a slit between the two lamellae of M1 and a heavy deposit between M1 and M2 (arrow); I, juvenile gametocyte showing a bundle of tubular structures (within a cisterna) and an electron-dense M3 membrane. Abbreviations: e, vacuole with phagosomal residues; ee, inclusion with electron-dense deposit; e', inclusion filled with electron-dense material; er, endoplasmic reticulum and connected cisternae; fi, food vacuole; g, Golgi; M1, 2 and 3 parasite's outer, median and inner boundary membranes; m, mitochondria; n, nucleus; t, tubular structures; tr, "trapezoid organelle"; v, vacuole. Scale bars: A-C, F-H, 1 µm; D, 2.5 µm; E, I, 0.5 µm.
