Antioxidant defence system (activities of superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidase), and free radical modification of lipids were determined in the gills from male and female brown trout (Salmo trutta m. trutta L.) affected by ulcerative dermal necrosis (UDN). In both males and females, lipid oxidation in the gills from UDN-affected trout showed higher values as compared to the respective control. UDN induced an increase of thiobarbituric acid reactive substances (TBARS) levels both in the gills of males and females. UDN caused a decrease in gill antioxidant enzyme activities. This might be due to inactivation of the abovementioned enzymes by the end products of lipid peroxidation. The importance of the glutathionemediated antioxidant defence system in protection against UDN-induced oxidative stress was demonstrated.
