Histopathological changes and oxidative stress associated with Fascioliasis in bovines

In this study, our objective was to gain insight into the pathophysiological consequences of Fascioliasis in cattle through the evaluation of metabolic, oxidative stress, and histological parameters. A thorough investigation was carried out on the liver of 197 bovines after their slaughter, which unveiled the occurrence of Fascioliasis, with a prevalence rate of 13.2% observed. The bovine that were infected exhibited notable increase in serum transaminases (ALT, AST, and ALP) and malondialdehyde (MDA) and catalase (CAT) while the decrease in glutathione (GSH) and superoxide dismutase (SOD) levels. The lipid profile analysis of infected cattle revealed alterations in the cholesterol and triglyceride levels. Moreover, the histopathological examination revealed a range of hepatic lesions associated with Fascioliasis, including necrosis, inflammation, fibrosis, and proliferative alterations. The bile ducts also displayed distinct pathological changes, including hyperplasia, thickening, and edema, and harbored various developmental stages ofFasciola spp. highlighting the parasitic infestation ’s effects on the biliary system. These results highlight the serious effects of Fascioliasis on lipid metabolism and the oxidative damage that is induced in the livers of cattle. Thus, Fasciola infestation in bovine causes alteration in biochemical and antioxidant activities, which are considered as important factors in the diagnosis of Fascioliasis.
