AB Juvenile rainbow trout Oncorhynchus mykiss were experimentally infected by immersionwith viral haemorrhagic septicaemia virus (VHSV), infectious haematopoietic necrosis virus(IHNV) or with both viruses. The presence of neutralizing antibodies in the sera of infected fish wereanalysed by 50% plaque neutralization tests (50%PNT). In Group 1 (infected with VHSV) and Group2 (infected with IHNV) neutralizing antibodies were found in 41% and 21% of the serum samples,respectively. No cross-reacting antibodies were found in these 2 groups. In Group 3 (infected withboth viruses) 30% of the samples showed neutralizing antibodies against VHSV, 21% against IHNVand 12% against both viruses. Fish in Group 3 developed a double specific antibody reaction whosekinetics and intensity (mean of log10 titres) were similar to the antibody response of the singleinfected groups.
