Lumpy Skin Disease in Cattle: Hematological, Biochemical and Oxidative Changes

Abstract

This study was conducted to determine the clinical, haematologic, biochemical findings, and oxidative stress parameters in cattle naturally infected with lumpy skin disease virus (LSDV) in the Kafrelshikh governorate, Egypt. Twenty animals were divided into 2 groups. Ten apparent healthy mixed Holstein female cows with age ranged between 1.5-3 years did not show any symptoms of LSD and considered the control group. Other 10 mixed Holstein pregnant females with an age range between 2-3 years considered diseased group by clinical examination and laboratory confirmation by polymerase chain reaction and analysis of the blood samples. The diseased cows suffered from fever (above 40∘C), anorexia, emaciation, skin nodules distributed in various body parts, lacrimation, nasal discharge, oedema, enlarged prescapular, and prefemoral lymph nodes. Haematological examination of the blood collected from infected animals showed a significant reduction in the number of erythrocytes, various leukocyte types, and thrombocytes as well as macrocytic hypochromic anemia.
