Abstract: The present invention provides a recombinant expression vector comprising a gene encoding canine parvovirus 2a VP2 or 2b VP2 protein, a recombinant plant into which the vector is transformed, a vaccine composition against canine parvovirus, comprising canine parvovirus 2a VP2 or 2b VP2 protein obtained from the recombinant plant, and a composition for diagnosing canine parvovirus. When the recombinant plant of the present invention is used, canine parvovirus 2a VP2 or 2b VP2 antigen protein can be rapidly produced with high efficiency. Since the composition for diagnosing canine parvovirus according to the present invention uses a recombinant antigen protein, there is no possibility of contamination due to live virus handling, and thus the composition is safe, and the presence or absence of canine parvovirus infection can be rapidly diagnosed from a large amount of samples.
