Light and electron microscope study of Sarcocystis sp. from the fallow deer (Cervus dama).

By means of light and electron microscopy a study was made of Sarcocystis sp. from 11 fallow deer (Cervus dama). Cysts of Sarcocystis sp. were found in the tongue and abdominal muscle of 3 of 11 deer from forests near Bonn (FRG). These measured 212-560 micron in length and 54-120 micron in width and contained metrocytes and merozoites. The cyst wall, which had narrow band-like protrusions, is compared with other Sarcocystis sp. from Cervidae.
