Evidence for natural recombination in the capsid gene VP2 of Taiwanese goose parvovirus

To investigate the possible role of recombination in the evolution of Muscovy duck parvovirus (MDPV) and goose parvovirus (GPV) in Taiwan, we analyzed a potentially significant recombination event that occurred only in GPV by comparing thirteen complete sequences of the capsid gene VP2 of GPV and MDPV. The recombination event occurred between GPV strain 06-0239 as the minor parent and strains 99-0808 as the major parent, which resulted in the GPV recombinant V325/TW03. GPV V325/TW03 is likely to represent a new genotype among the Taiwanese GPV strains. This represents the first evidence that intergenotype recombination within the VP2 gene cluster contributes to the genetic diversity of the VP2 genes of Taiwanese GPV field strains.
