Malondialdehyde (MDA), catalase (CAT) and reduced glutathione (GSH) levels in gilthead sea bream naturally co-infected with E. sieboldi and V. alginolyticus analyzed in the gills, skin, and muscle tissues. White bar represents uninfected control fish, while black bar represents infected fish. The bars represent the mean ± standard error of the mean. Values are statistically significant at p value < 0.05 (Independent sample T-test, R 4.1.2). * (p value < 0.05), ** (p value < 0.01) and *** (p value < 0.001)
