Abstract
The present work has been carried out to study the haemato-biochemical profiles of cattle infected with oriental theileriosis. Theileriosis was diagnosed in 30 cross bred cattle by blood smear examination and confirmed by PCR. Whole blood samples were collected from positive animals and were subjected to estimation of haemato-biochemical parameters. Haematological analysis revealed significant decrease in total erythrocyte count (TEC), haemoglobin, volume of packed red cells (VPRC) and granulocyte count, significant increase in total leucocyte count (TLC), lymphocyte count, monocyte count and granulocyte count in T. orientalis infected animals. Non-significant changes were noticed in mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC). Biochemical analysis revealed significant decrease in albumin concentration and significant increase in blood urea nitrogen level in T. orientalis infected animals. The knowledge on alterations in haemato-biochemical profiles of affected animals will help to assess the severity of infection and to make a tentative diagnosis of the condition.
