Comparison of antibody responses in Atlantic cod (Gadus morhua L.) to Aeromonas salmonicida and Vibrio anguillarum.

The immune system of Atlantic cod (Gadus morhua L.) differ from other bony fish species in that no or only very low increases in antibody levels are detected post-immunization with Vibrio salmonicida or V. anguillarum.

Respiratory burst activity of Atlantic cod (Gadus morhua L.) blood phagocytes differs markedly from that of rainbow trout.

In the present study we investigated the respiratory burst (RB) activity of Atlantic cod (Gadus morhua L.) blood phagocytes and we evaluated how the RB activity of cod blood cells differ from that of trout. The RB activities were measured directly from highly diluted whole blood as luminol-amplified chemiluminescence (CL) under various conditions.
