Abstract

Bovine Tropical Theileriosis (BTT) is caused by blood protozoa Theileria annulata in cattle, which causes high mortality among the animals and impacts huge economic losses to the farmers. It decreases the milk yield and impairs reproductive performances. Measurement of erythrocytic oxidative stress is a need of hour for effective treatment and management of this disease now a day. Oxidative stress and lipid peroxidation in erythrocytes of cattle infected with the intra erythrocytic protozoa results in increased fragility and membrane lysis of erythrocytes which is the major concern of this study. A group of 10 cattle affected with bovine tropical theileriosis were taken as Group II along with another 10 animals (apparently healthy animal) as Group I. The erythrocytic oxidative stress indices along with the haemato-biochemical parameters were measured for both the groups. It was found that there was significant increase (p
