| Abstract: | The genomic DNA of porcine parvovirus (PPV) Z strain cultured with PK15 cells was extracted and its NS1 gene was amplified and sequenced. The amplified product is 330 bp in length, encodes 109 aa. The sequence of amino acids contains the important and conserved sequence, and has the potential N glycosylation site NFSN. NS1 gene of the strain exhibits 99%, 98% and 98% nucleotide sequence identities with other PPV strains such as Kresse, NADL2 1 and NADL2 2 respectively, the sequence of amino acids of the strain exhibits 99% identity with those of the mentioned above three strains. |
