Fifteen out of 75 native cattle 5-7 years old from different localities at Sharkia Provence were used to study hematological changes in Babesia and Theileria infestation verified with the clinical signs during period from May 2009 to the end of April 2010. Animals were allotted into three groups (n=5/each), 1st group were healthy cattle free from blood parasite (control), 2nd group were suffering from babesiosis and 3rd group were suffering from theilerosis. Clinical examination included body temperture, rate of respiration and ruminal movment. Two blood samples were collected from each animals for determination of erythrogram and leukogram changes in whole blood and some biochemical parameters in seprated sera. The results revealed that body temperture and respiration rate were significantly increased in cattle suffering from babesiosis and thelariosis while ruminal movement were significantly decreased. Hematological picture revealed a significant reduction in RBCs, HB and PCV in cattle infected with eitheir babesiosis or theileriosis. Babesiosis induce significant reduction in MCV, MCH and MCHC (microcytic hypochromic anaemia) while theileriosis induced increase in MCV and decrease in MCH and MCHC (macrocytic hypo-chromic anaemia). Bovine infected with babesiosis and thelariosis revealed leukopenia, neturopenia and eosinopenia accompanied with lymphocytosis, monocytosis and basophilia compared to that of control group. The result of biochemicaly analysis showed that cattle infected with babesiosis and theileriosis revealed significant reduction in total protein, albumin, globulin, cholesterol, Triglycerides and glucose levels associated with significant increase in the activities of liver enzymes (AST, ALT, alkaline phosphatase) and total bilirubin. It could be concluded clinical signs namely red brown to coffee urine (in babesiosis), enlargement of superfacial lymph nodes, corneal opacity and macrocytic hypochromic anaemia (in theileriosis) in addition to hematological picture (microcytic and macrocytic hypochromic anaemia in babsiosis and theilorosis, respectively) could be useful for easily diagnosis of blood parasites
