Abstract

Shrimp farming industry experiences massive losses due to white faeces syndrome (WFS) infection. The virus causes oxidative damage in shrimp tissues, subsequently resulting in shrimp mortality within a relatively short time. This study aimed to evaluate the changes in antioxidant defence mechanisms and the level of protein oxidation and lipid peroxidation in the hepatopancreas, gills and flesh of WFS-infected Litopenaeus vannamei under laboratory conditions. The experimental animals were injected with WFS, and hepatopancreas, gill and flesh samples were collected at intervals of 0, 24, 48, and 72 hours post-infection. Lipid peroxidation, protein carbonyl contents, and antioxidant enzyme activities, including glutathione peroxidase (GSH-Px), catalase (CAT), and superoxide dismutase (SOD), were analysed in WFS-infected shrimps. Interestingly, protein carbonyl and lipid peroxidation as oxidative markers in the shrimp’s tissue were higher in infected organs than in uninfected controls. Additionally, a significant drop in GSH-Px activity was observed over the 72-hour period post-infection in all of the infected tissues analysed, with different trends observed for CAT-SOD activities. Thus, the results demonstrated that the endogenous antioxidant defences in WFS-infected shrimp failed to counteract the presence of excessive free radicals during the 72-hour period post-infection, leading to inactivation of enzymes in infected shrimp.
