ABSTRACT

Endoparasites cause significant economic losses and health problems in domestic animals. In this study, lipid peroxidation and the antioxidant status were investigated in the lung tissue taken from twenty cattle infected with Dictyocaulus viviparus and ten healthy cattle. Malondialdehyde superoxide dismutase, catalase, glutathione, vitamin C and β-carotene were measured. In comparison to the control group, the concentration of MDA was high (p< 0.001), but the activities of Cu-Zn-SOD and CAT, and the concentration of GSH, vitamin C and β-carotene were low (Cu-Zn-SOD, CAT, GSH, vitamin C, p< 0.001 and β-carotene p< 0.05) in the parasite infected group. These results suggested that endoparasitic infection is among the major causes of oxidative stress. Lipid peroxidation was observed and the activities and concentrations of antioxidants systems were decreased in the lungs of cattle infected with Dictyocaulus viviparus.
