CLINICAL ,HEMATOLOGICAL AND DIAGNOSTIC STUDIES OF HEMOMYCOPLASMA INFECTION (MYCOPLASMA OVIS) IN SHEEP OF BASRAH GOVERNORATE

Hemomycoplasmosis caused by Mycoplasma ovis was diagnosed in sheep of Basrah Governorate .The study were conducted on (225) sheep reared in different areas of Basrah governorate . Animals are of different ages and of both sexes. Twenty five clinically healthy sheep were considered as controls .Complete clinical examinations were applied to all animals, and fecal samples screened for parasitic loud. Results revealed that infected sheep show signs of anorexia , anemia with pale or icteric mucous membranes of eyes and vagina , rapid and difficult respiration , enlargement of superficial lymph nodes, rough wool coat and hemoglobinuria, Moreover milk production were decreased in lactating ewes . On clinical examinations statistically significant increase were indicated in body temperature ,respiratory and heart rate of diseased sheep then in controls. Diagnosis of Mycoplasma ovis were leant on examination of stained blood smears with Giemsa ,Since the organism appear as small coccoid or rod shape structures and it could be found as an singular or in chains on the cell membranes of infected erythrocytes of diseased animals , Furthermore the diagnosis were confirmed by indirect Elisa test . Results of hematological examinations show significant decrease in the values of total erythrocytes count ,hemoglobin concentration and packed cell volume indicating macrocytic normochromic type of anemia, However , the rate of sedimentation of red blood cells indicated significant increase in diseased sheep, Moreover , Leucocytosis due to significant increase in lymphocytes number were also registered in infected sheep then in controls , In addition evaluation of acute phase response show significant decrease in haptoglobin values and fibrinogen time in diseased sheep compared with controls . Significant decrease in total protein were detected, However285 values of total and indirect bilirubin, GGT, AST, ALP, and BUN were significantly increased in diseased sheep compared with controls. It had been concluded that Hemomycoplasmosis ovis were infected sheep of Basrah governorate lead to hemolytic anemia and substantial effect might terminated with highly mortalities , Therefore all suspected sheep in the chancy area must screened for microorganism loud
