| Popis: | This experimental studies investigated the protective efficiencies and the potential immune mechanisms of vibrio monovalent and polyvalent autogenous formalin-inactivated whole-cell bacterins (FKC) in Gilthead sea bream (Sparus aurata) cultured in Egypt. Two months post-vaccination, the relative percentage survival (RPS) was estimated after challenge with the vaccine's homologues pathogenic strains. The survival values were 100% and 83.3% in groups immunized with monovalent V. alginolyticus or V. parahaemolyticus FKC bacterins, respectively. On the other hand, survival values were 91.75% and 75% in fish groups subjected to polyvalent (V. parahaemolyticus O11: K40V. alginolyticus) and (V. parahaemolyticus O3: K6V. alginolyticus) FKC bacterins, respectively. Overall, the tested vaccine preparations were significantly increased (P 0.05) the agglutination antibody titer, phagocytic activity, respiratory burst activity, when compared to the non-immunized control group. The current results conclude that, autogenous Vibrio vaccines provoked a promising protection against vibriosis in Gilthead sea bream cultured in Egypt, it was superior in monovalent FKC V. alginolyticus vaccine and polyvalent FKC of V. parahaemolyticus O11: K40 with V. alginolyticus vaccine that could be useful means of prevention and control of vibriosis. |
