The invention relates to the sequence of the capsid gene and a corresponding
cDNA sequence, of a dominant FCV strain called FCV 431. It also relates to the
sequence of the capsid gene as well as the cDNA sequence of a complementary strain
called G1. The cDNA sequences may be incorporated into expression vectors for the
preparation of immunogenic preparations and of recombinant or subunit vaccines
allowing vaccination against feline calicivirosis.
