The cyst forming parasite has obligatory two hosts life cycle including carnivorous as definitive host and omnivorous or herbivorous as intermediate host. The parasitic infestation causes serious health problems and economical loses because of abortion in pregnant animals, carcass condemnation after slaughtering due to severe emaciation and pathological lesions, low quality of meat, milk and wool, as well as restriction on animal importation by authorities.Methods: The present work was conducted to study the prevalence of sarcocysts infection in slaughtered cattle at Duhok abattoir, Iraq. Muscle samples from different organs comprising esophagus, diaphragm and heart were collected from 150 cattle aged from one to two years old. Different techniques were used for detection of macroscopi...

The prevalence of Sarcocystis species (Sarcocystis ovicanis and Sarcocystis capricanis) in tongue muscle of sheep and goats that collected from abattoir and outside of abattoir (at Butchers Markets) in Duhok province was determined for the first time during the period of 4 months from September 01, 2014, to January 03, 2015. Three techniques were applied for this purpose. Direct scotch cellophane adhesive tape test, muscle mincing and squash method, and pepsin digestion technique. The overall prevalence was 97% in sheep and 100% in goats. No significant difference (p>0.05) was obtained between male and female of both species. Histopathological analysis revealed different size and shape of microcysts with thick cyst wall, in addition to mild histological changes. Index Terms-Microcysts, Sarcocystis species (Sarcocystis ovicanis and Sarcocystis capricanis), Tongue muscle of sheep and goats.

Physical examination of the dog revealed generalized lymphadenopathy, strong pale mucous membrane, systolic murmur of the heart, vomiting, bloody diarrhea and fever. Hematological abnormalities indicated moderate to marked leukocytosis characterized by 89% neutrophilia with a left shift to progranulocytes and 1.6% presumptive myeloid blasts, marked thrombocytopenia, marked non-regenerative normocytic hypochromic anemia and dysplasia in platelets and neutrophils. The histopathological examination revealed excessive infiltration with neoplastic myeloid cells that invaded all the internal organs. Bone marrow analysis revealed marked hypercellularity with a predominance of immature cells, marked myeloid 6.2%, dysplasia of neutrophils lineage and rare erythroid progenitors and numerous megakaryocytes. Enlargement of superficial and visceral lymph nodes and internal body organs, especially liver and spleen were observed in the autopsy after animal euthanasia. Our results confirmed that this dog was suffering from chronic myeloid leukemia. Statistically, there was a significant difference (P < 0.05) between the mean value of myeloid blasts in peripheral blood and bone marrow. But, no significant difference (P > 0.05) was found between the mean values of leukocytic ratio in peripheral circulation and bone marrow. This is the first case report study that has been recorded in a native shepherd dog in a rural area around Duhok province/ Iraq.
