摘要： In this study, we sequenced and analyzed the complete genomes of the porcine parvovirus 7 (PPV7) isolated in Fujian, Southeast China. Genomic comparison revealed that PPV7 isolates in Fujian shared higher (more than 98.5%) nucleotide homology and closer relationship with other PPV7 strains. Phylogenetic analysis based on NS indicated that PPV7 formed a distinct cluster (proposed Chapparvovirus) closer to subfamily Parvovirinae. However, phylogenetic analysis based on genome and VP showed that PPV7 isolates formed a distinct cluster closer to subfamily Densovirinae. No recombination event observed suggesting recombination did not contribution to the genetic diversity of PPV7. These findings demonstrated that PPV7 continuous circulating in China, which may help us to understand the evolution diversity of porcine parvoviruses.
