Abstract: The present invention is directed to a reassorted ISA virus comprising Genome segments 1-8 wherein at least one genome segment is from Genotype I and at least one genome segment is from genotype II, wherein genome segment 6 is of Genotype II. The reassorted ISA virus was found to grow well in suspension culture. The present invention is also directed to method to make the reassorted virus as well as vaccination methods using the reassorted ISA virus and to vaccine compositions comprising the reassorted ISA virus.

Abstract: A vaccine composition comprising a virus antigen wherein the composition comprises less than 5% serum, wherein the virus antigen is a whole virus or derived from a whole virus, the vaccine composition reduces, prevents or avoids cross-stitch spinal deformity in the treated animal. Said vaccine composition for use in a method of treating a disease caused by the intracellular pathogen in an animal and reducing, preventing or avoiding cross-stitch spinal deformity in the treated animal. In cross-stitch vertebra the intervertebral space is completely collapsed. A vaccine composition for use as defined above wherein the animal is a fish. In an embodiment the pathogen is salmon alpha virus (SAV).

Abstract: The invention relates to recombinant novirhabdoviruses having at least one sequence encoding a polypeptide of interest added to their genome. Said recombinant novirhabdoviruses are useful as gene vectors, for producing recombinant proteins, or for producing vaccines for fish or for higher vertebrates.
