Abstract
Aim: The present study was carried out to investigate the effect of Aeromonas hydrophila infection on some biochemical parameters including serum IgM, and lipid peroxidation marker malondialdehyde (MDA), reduced glutathione (GSH), superoxide dismutase activity (SOD), and catalase (CAT) levels in spleen of Nile tilapia. Materials and methods: The fish were divided into three groups: control (non-infected, n = 20), resistant (infected but no symptoms, n = 20), and diseased/susceptible (infected with symptoms appeared, n = 20). Results: Infected fish showed typical A. hydrophila infection clinical signs and post mortem lesions (exophthalmia, hemorrhages and erosion in fins, scales desquamation, severe enteritis with yellow mucous in intestinal lumen, congested liver with enlarged gall bladder). The serum level of the IgM was significantly increased in the resistant fish than the control and susceptible fish. Moreover, GSH level and activities of CAT and SOD were significantly increased in the spleen of control and resistant fish than the susceptible (diseased) fish. However, spleen MDA level was significantly increased in susceptible fish than the control and resistant fish. Conclusion: Fish resistant to A. hydrophila infection had higher serum IgM level, spleen GSH content and antioxidant enzyme activities (CAT and SOD) and lower MDA levels in the spleen.

Key words: Aeromonas hydrophila; oxidative stress; Nile tilapia; immunity.
