The means and standard deviations for antibody concentration COD-values) against V,
unguillurum and V. sulmonicidu O-antigens and body weight at the first, second and
third sampling are shown in Table 1. Mean antibody concentration against V. unguillurum
O-antigens showed a significant decrease after first immunisation compared with
the initial antibody concentration. Antibody concentration increased significantly after
the second immunisation. There was a small but significant increase in antibodies
