Abstract: A strain of goose parvovirus (SS/10) was isolated from gosling hepar and biological characteristics of the virus were studied.The result indicated that the ELD50 to muscovy duck embryos was 10-4.6/0.3 mL and no goslings were dead after inoculation,but pathological change by tissue section was evident. Sequence analysis showed that the homology with DY strain was lower than other reference strains in VP1,VP2 and VP3 genes respectively and there was no difference in NS1 and NS2 genes; VP3 gene belonged to a branch with 82-0321V,VG32/1 and B strains published in GenBank. It had closest genetic relationship with 82-0321V and farthest genetic relationship with muscovy duck parvovirus GD strain. Glycosylation sites analysis showed that VP3 had one less glycosylation site than B.
