title: Prevalence of sarcocysts in livestock of northwest Ethiopia.
abstract: A survey of Sarcocystis was conducted in cattle, sheep, goats, donkeys and chickens. A total of 671 haematoxylin-eosin (H-E) stained muscle tissue samples, including diaphragm, masseter, cardiac and oesophageal musculatures were examined. Additionally, cardiac muscle samples from 40 fetuses were included. An infestation rate of 93% in sheep, 82% in cattle, 81% in goats, 16.6% in donkeys and 6.6% in chickens was noted. The infestation rate of diaphragm, masseter, cardiac and oesophageal musculatures seems to be similar. None of the 40 fetal heart muscle samples from bovine, ovine, caprine and donkey fetuses examined harboured Sarcocystis. An attempt was made to demonstrate the possible occurrence of human Sarcocystis and a negative result was obtained. The possible impact of Sarcocystis on animal health in Ethiopia is discussed.
