From: Descriptions of Mikrocytos veneroïdes n. sp. and Mikrocytos donaxi n. sp. (Ascetosporea: Mikrocytida: Mikrocytiidae), detected during important mortality events of the wedge clam Donax trunculus Linnaeus (Veneroida: Donacidae), in France between 2008 and 2011

Fig. 7

Transmission electron microscopy of Mikrocytos veneroïdes n. sp. infecting Donax trunculus mantle collected in Quiberon Bay. a Parasite inside a myocyte and near the myofibrils. Note the presence of mitochondria near the parasite cells (arrow). b Parasite in the cytoplasm of a haemocyte; note the presence of parasitophorous vacuole around the parasite (arrows). c Parasite near the myofibrils. Mitochondria tight against the surface of the parasite or inside the parasite cytoplasm; note the depression of parasite surface at the point of contact with mitochondria. d Binucleate stage of the parasite in an extracellular position; note the presence of the two nuclei. Abbreviations: M, mitochondria; MF, myofibrils; N, nucleus; P, parasite. Scale-bars: a, b, d, 2 μm; c, 1 μm
