Abstract
We report here the complete genomic sequence of the porcine parvovirus (PPV) N strain, isolated in 1989 from the viscera of a stillborn fetus farrowed by a gilt in Guangxi, southern China. Phylogenetic analyses suggest that the PPV-N strain is closely related to attenuated PPV NADL-2 strains. The PPV-N strain has good immunogenicity, genetic stability, and safety.

Natural attenuated porcine parvovirus N strain (PPV-N strain) was isolated in 1989 from the viscera of a stillborn fetus farrowed by a gilt in southern China [5]
The PPV-N strain was developed for a PPV attenuated vaccine, and animal testing showed that it has good immunogenicity, genetic stability, and safety [6,7,8,9]
Summary
We report here the complete genomic sequence of the porcine parvovirus (PPV) N strain, isolated in 1989 from the viscera of a stillborn fetus farrowed by a gilt in Guangxi, southern China. Porcine parvovirus (PPV) was discovered by Mary and Mahnel while performing tissue culture of classical swine fever virus in 1966. PPV is one of the main pathogens causing swine reproductive disorders and fetal malformation.
