| الملخص: | 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 |
