Histopathology findings of the liver tissue of frogs infected with parasites Hepatozoon sp. a, Hepatozoon sp. b, and Lankesterella minima. Meronts (arrowhead in (a), and enlarged version in (b) of Hepatozoon sp. a in liver with evidence of lymphocyte and eosinophil infiltration resembling a granuloma-like lesion (a-b), diffuse multifocal meronts of Hepatozoon sp. b with infiltration by a few inflammatory cells (c-d), meront (arrowhead in (e)) of Lankesterella minima presented in liver, with an increase in melanomacrophages centre (MMCs) and a mild tissue reaction (e), evidence of liver damage associated with a merozoite of Lankesterella minima surrounded by an MMC (f), Mer = meront, haematoxylin-eosin (a, c: Bar = 20 μm and b, d: Bar = 6 μm and e, f: Bar = 15 μm).
