There are two type of the host in the life cycle of this parasites definitive and intermediate host (<a href="#Fayer-R--Leek-RG--1979-"><span class="Hyperlink">Fayer and Leek, 1979</span></a>). There are two phase in the infection with sarcocystosis intestinal phase occurs in the definitive host and tissue phase which seen in the intermediate host. More than hundred species of <span class="CharOverride-4">Sarcocystis</span> are parasites of domestic and wild animals, many of these infections are asymptomatic, particulary in the definitive host (<a href="#Beaver-PC--Gadgil-RK--Morero-P--1979"><span class="Hyperlink">Beaver et al., 1979</span></a>). Several species of <span class="CharOverride-4">Sarcocystis</span> parasites infected Sheep  like <span class="CharOverride-4">S. tenella </span>(<span class="CharOverride-4">S. ovicanis</span>),<span class="CharOverride-4"> S. arieticanis, S. gigantea </span>(<span class="CharOverride-4">S. ovifelis</span>)<span class="CharOverride-4"> and S. medusiformis</span> where dogs (for first two species) and cats (for last two species) are the final hosts (<a href="#Aiella-SE--Mayes-A--1998-"><span class="Hyperlink">Aiella et al., 1998</span></a>). In general, the <span class="CharOverride-4">Sarcocystis </span>spp., by canidae or primates is more pathogenic than those transmitted by felids. Intermediate hosts show symptoms of fever, anemia, weight loss, reduction of wool quality and milk yield, abortion and CNS. Signs are mainly death in many cases. In the final hosts diagnosis of the Sarcocystosis depened on detection the sporocyst by feacal analysis , and in the intermediate hosts the diagnosis done by investigated the asexual stages as cyst or their contains (cystizoites) in the muscles by several trichinoscopy (<a href="#Scott-WT--1930--."><span class="Hyperlink">Scott, 1930</span></a>; <a href="#Daoud-IS--1976"><span class="Hyperlink">Daoud, 1976</span></a>), Peptic digestion technique for the muscles (<a href="#Jacobs-L--Remington-JS--Melton-ML--1960"><span class="Hyperlink">Jacobs et al., 1960</span></a>). Cytogenetic analysis is a widely employed indicator system for induced mutations. It allows objective evolution of insults to the genetic martial and is a method that permits visual analysis of chromosome damage (<a href="#Sinues-B--Izquierdo-M--Niguera-JP--1990"><span class="Hyperlink">Sinues et al., 1990</span></a>; <a href="#Tucker-JD--Preston-RJ--1996-"><span class="Hyperlink">Tucker and Preston, 1996</span></a>) +lymphocyte of affected ewes by using blood samples. </p>

			<p class="Body-Text ParaOverride-1">Five millilitres of blood samples in heparinized tube were collected from jugular vein of 60 ewe before slaughter. 0.4 ml of the heparinized blood samples, obtained from the subjects, were placed in sterile culture tubes containing 5 ml of Qunitum medium. Gently shaking the contents of each culture tube and then incubated in a slanted position at 37°C for 72 h. After 70 h of incubation, 0.1 ml of colcemid solution (10 μg/ ml) was added to each culture tube and mixed by shaking gently. After replace of 72 h of incubation, the tubes were centrifuged at 2000 rpm for 4 min. and the supernatant was discarded. The pellet was resuspended using 10 ml of hypotonic solution (0.075M KCl) and the tubes were incubated at 37°C for a further 4 min. After the tubes were centrifuged at 2000 rpm for 4 min., the supernatant discarded, and the pellet was resuspended using 10 ml of fresh fixative solution (methanol and acetic acid, 3:1). The tubes were centrifuged at 2000 rpm for 4 min. and the supernatant was discarded. This procedure was repeated 3 times. The pellet was resuspended and 0.5-1 ml of fresh, cold fixative solution was added to the tubes. Then 3 or 4 drops of the cells suspension were dropped on to a cold wet glass slide. Dried slides were stained with 5% Giemsa stain. Mitotic index (MI) was determined as a percent of the Mitotic cells interphase nuclei in 1000 cells. Replicative index (RI) was determined by counting the number of cells at the first, second and the third in (100) cells at metaphase (<a href="#Rooney-DE--Czepulkowski-BH--1986"><span class="Hyperlink">Rooney and Czepulkowski, 1986</span></a>). </p>

			<p class="Body-Text ParaOverride-1">To determine the frequency of Sister Chromatid Exchange (SCE) in the lymphocytes, 1–2.5 ml sample of peripheral blood from each individual was added to 5 ml of chromosome medium supplemented with 5 μg/ml of phytohaemagglutinin. BrdU (5–bromo–2–deoxyuridine,) was then added to each culture (10-4 M final concentration) and the cultures were incubated in complete darkness for 72 h at 37°C. Colchicine (final concentration 0.5 μg/ml) was added to each culture during the last 2 h of the incubation to block the cells in the metaphase stage of mitosis. Upon completion of the incubation, each cells culture was subjected to hypotonic treatment by adding 8 ml of 0.075 M KCl and was maintained for 30 min at 37°C. Three repetitive fixations of each cells suspension were then performed with cold methanol/acetic acid (3:1, v/v). An aliquot of each cell suspension was then dropped onto a cold slide. The slides were dried at room temperature, and then kept in the dark for 3 days after which they were stained using acridine orange method. The number of SCEs was counted in at least 50 metaphases in each sample from each individual. The number of SCEs per metaphase was scored for each individual (<a href="#Rooney-DE--Czepulkowski-BH--1986"><span class="Hyperlink">Rooney and Czepulkowski, 1986</span></a>).</p>

Banan shaped bradyzoites in the digested muscle tissue are shown in (<a href="#Figure-1-"><span class="Hyperlink">Figure 1</span></a>). The present study raveled the high rate with ovine sarcocystosis. This finding agreed with previous studies in Iraq (<a href="#AL-Delemi-JKA--1992-."><span class="Hyperlink">AL-Delemi, 1992</span></a>; <a href="#AL-Bayati-SM--2008-"><span class="Hyperlink">AL-Bayati, 2008</span></a>).
