Transmission electron micrographs (A and B) and a histological image (C) of Mikrocytos mackini in the cells of Crassostrea gigas and Ostrea edulis, respectively, from British Columbia, Canada. A. Protist (p) against the host cell nucleus (hn) and two closely associated host mitochondria (hm). B. Higher magnification of a host mitochondrium (hm) with tube-like structures (arrows) extending into the cytoplasm of M. mackini (p). C. Several M. mackini (p) in the cytoplasm of vesicular connective-tissue cells (hn, nuclei of host cells) of the labial palps of O. edulis. D. Tissue imprint of the gonad of Crassostrea gigas from Japan with a sporangiosorus (s) of Marteilioides chungmuensis in each ovum against the host cell nucleus (hn). Each sporangiosorus contains two sporonts and each sporont contains one basophilic developing spore. A and B bars = 0.5 µm , C and D bars = 10 µm.
