Aims

It is the 1st time to study sarcosysts meisheri of camels in Assiut Govemorate; throughout the study different parts from camels in different locations were examined for Sarcosystis meisheri. (Abdominal, esophagus and tongue muscles).Therefore, the present study aimed to investigate the prevalence of Sarcocystis meisheri . Infection among slaughtered camels in Assiut, Upper Egypt and to examine the ultrastructural characteristics of the sarcocystis meisheri inside the different muscles of camels.

Main methods

Random samples of different regions of camel muscles (0esophagus, tongue and abdominal region) were collected for examination of any Sarcocystis meisheri in muscles.

Key findings

One hundred and ninety five (195) specimens were examined. Only one hundred and eight (108) were found to be infected (55.5%).The infectious rates was highest in esophagus (62%), followed by abdominal muscles (52.2%) and tongue muscles (51.25%).

Significance

Generally the infectious rate with the parasite was higher in males than in females. Morphological and ultrastructures of muscle stage (sarcocyst) have been reported and illustrated in this study by both light and electron microscope. TEM showed that there are two types of Sarcocystis meisheri in camels in Assiut Governorate. The cyst consists of two types of cells these are metrocytes and merozoites and contained a large numbers of micronemes, rhopries, conoid and and mitochondrial organelles.
