Prevalence of sarcocysts in one-humped camel (Camelus dromedarius) from southern Ethiopia.

A survey of sarcocystis was made in camels from southern Ethiopia during a part of 1998-99. A total of 605 haematoxylin and eosin-stained tissue samples from cardiac, diaphragm, shoulder, masseter and oesophagus muscles of 121 adult camels and 20 tissue samples from four foetuses were examined for sarcocysts. Sarcocysts were detected in 55 of 121 (45.45%) camels examined. The infestation rate of oesophagus, diaphragm, shoulder, masseter and cardiac musculatures were 19.83, 11.57, 12.4, 8.26 and 9.17%, respectively. There was no significant (P > 0.05) variation between males (48.6%) and females (40.82%), nor between the two sites studied (Dollo Addo, 40.00% versus Neghelle Borana 47.25%). None of the 20 tissue samples from the four foetuses examined harboured sarcocysts. The possible impact of sarcocysts on camel production is indicated. This is the first report of the presence of sarcocysts in camels from Ethiopia.
