Hemolivia sp. in erythrocytes of the freshwater turtle Rhinoclemmys pulcherrima manni; all figures are in the same scale. Trophozoite is slim, cucumber-shaped, pointed towards one pole, and its cytoplasm contains small vacuoles. Nucleus (marked by black arrow) formed by granulated chromatin is placed sub-centrally (A). Developing meronts contain blue granulated or foamy cytoplasm without distinct nuclei (B, C). Young gamonts have nuclei in the centre (black arrow, D), their size grows, nucleus (marked by black arrow) heads towards one pole of parasitophorous vacuole (E), but sometimes is not visible (F). Mature gamonts have typical stain-resistant vacuole, nucleus in polar position (G, H), and their arms can be crossed forming a visible thin blue “X” (black arrowhead, H).
