Hematology Survey and Serum Calcium, Phosphorus, Magnesium and Glucose Analysis in Infected Calves with Theileriosis

Hematologic changes and serum biochemical analysis of 20 naturally infected and 15 non-infected calves with theileria annulata were carried out. Theileriosis was confirmed by observing theileria merosoites in red blood cells of peripheral blood smears of calves. Two blood samples were taken from the jugular vein in disposable polyethylene tubes one with anticoagulant (EDTA) for hematology and another 10 ml without anticoagulant substance for biochemical analysis. Compare the results the patient and control groups performed with Spss software and "t" test in the P<0.05. The results of this study showed that hematocrit, hemoglobin, red blood cells (RBC) count, platelets count and serum total protein were significantly reduced in calves infected with theileria (infected calves) compared with healthy calves (control group). Calcium, magnesium and glucose concentrations were also decreased in infected calves, but this was significant only in calcium. Phosphorus concentration had increased but this was not significant statistically. The results of present study shows that theileriosis in calves causes significant decrease in serum calcium which as new finding special attention should be paid when treating animals in addition to the disease specific treatment.
