Identification of recombination between Muscovy duck parvovirus and goose parvovirus structural protein genes

Waterfowl parvoviruses are divided into Muscovy duck parvoviruses (MDPVs) and goose parvoviruses (GPVs). Phylogenetic analysis based on structural gene nucleotide sequences showed that the strains of three GPVs (DY, PT and D strains) and two MDPVs (GX5 and SAAH-SHNH) are closely related and formed one cluster. Recombination analysis showed that recombination between GPV-GDFsh and MDPV-89384/FRANCE strains led to five recombinant strains: GPV-DY, GPV-PT, GPV-D, MDPV-GX5 and MDPV-SAAH-SHNH. The recombinant event was confirmed using the Simplot program and phylogenetic analysis. This is the first comprehensive investigation of recombination between MDPV and GPV structural genes.
