Vaccination of Atlantic halibut Hippoglossus hippoglossus L., and spotted wolffish Anarhichas minor L., against atypical Aeromonas salmonicida

Summary

Atypical furunculosis caused by atypical Aeromonas salmonicida is an increasing problem in commercial halibut farming, and a potential problem in farming of spotted wolffish in Norway. Halibut, Hippoglossus hippoglossus L., and spotted wolffish, Anarhichas minor L., vaccinated with oil-emulsified vaccines against atypical furunculosis, demonstrated a relative percent survival (RPS) of approximately 90 when challenged with homologous isolates. Bath and aqueous injection vaccines failed to protect against disease when challenged 10 weeks post-vaccination. High antibody titres were produced in both species after vaccination with oil-emulsified vaccines, and the major antibody response were against A-layer, LPS and some minor outer membrane (OM) proteins.
