Immune Response To Stress Induced By Corticosteroid In Common Carp (Cyprinus Carpio Linnaeus) Exposed To Aeromonas Hydrophila
C.Lumanlan, Susan (1993) Immune Response To Stress Induced By Corticosteroid In Common Carp (Cyprinus Carpio Linnaeus) Exposed To Aeromonas Hydrophila. Masters thesis, Universiti Pertanian Malaysia.
The effect of simulated stress induced by cortisol implantation in common carp ( Cyprinus carpio ) was studied. Humoral mediated responses to injected antigens following cortisol treatment were assessed by using the passive haemolytic plaque technique and indirect haemagglutination assay . A single cortisol implant and subsequent challenge to Aeromonas hydrophila elicited modulation in the fish immune system and also histopathological changes in the kidney, spleen and thymus . Hyperglycaemia which is a stress related physiological change was associatively manifested. The marked reduction in haemolytic plaque forming cells in cortisol treated carps indicated the suppression of antibody mediated response ..Similarly , a quantitative decrease in haemagglutinating antibody titre suggested that the immunosuppressive action of cortisol could have a pernicious effect on the fish's ability to resist infection
