AB  - Sarcocyst species are intracellular protozoan parasites with 
  an intermediate-definitive host life cycle based on a prey-predator relationship. 
  A sexual stages develop in intermediate hosts after they ingest the oocyst stage 
  from definitive-host feces and terminate with the formation of intramuscular 
  cysts (Sarcocystis). The present study was carried out to find out the incidence 
  of sarcocystosis (in sheep) in three slaughterhouses in Iran. A total of 650 
  muscle samples of 325 sheep from 4 different age groups were surveyed by the 
  digestion and impression smear examination methods for the presence of Sarcocystis. 
  After slaughtering, esophagus and diaphragm were examined for macroscopic cyst 
  of Sarcocystis. For microscopic cysts, the samples were taken from each one 
  of these tissues for impression smear (Dob smear) and digestion. Macrocysts 
  were found in 4.3% (14/325) of sheep and the highest prevalence was detected 
  in the diaphragm in all age groups. Microcysts were present in 92% (299/325) 
  of sheep. There was no significant difference (p>0.05) statistically between 
  sensitivities of two diagnostic methods (digestion and impression smear) in 
  detecting Sarcocystis species. These results reveal the fact that the environment 
  is heavily contaminated with sporocysts and the ingestion of sporocysts by sheep 
  begins from the young ages in Iran.
