One known Sarcocystis species and one found for the first time in fallow deer (Dama dama).

Sarcocysts of free-ranging indigenous fallow deer (Dama d. dama) from northeast Germany and captive Persian fallow deer (Dama dama mesopotamica) from the Zoo Berlin-Friedrichsfelde were described using the transmission electron microscope. Two Sarcocystis species (Sporozoa, Sarcocystidae) were found in D. d. dama, one of them already known, the other new for this host. The known species was also found in D. dama mesopotamica. Comparing the literature, former own findings in roe deer, red deer or wapiti with the results reported in this paper, we conclude that the two Sarcocystis species should be designated as S. cf. grueneri (known in Dama but not named) and S. cf. hofmanni (new for Dama).
