ABSTRACT: Goose circovirus (GoCV) is a common pathogen that causes immunosuppression and promotes secondary infections with other infectious agents in geese worldwide. In the present study, we identified GoCV in 2 out of 93 duck flocks from China and successfully sequenced the complete genomes of 2 strains (AH22du and HN20du). The whole genome of the two strains shared a high identity of 90.5 to 98.63% with China GoCV reference, and low identity of 58.98% with DuCV reference, respectively. Phylogenetic tree constructed on the two and other genome sequences of GoCV revealed three main branches. Both strains sequenced in this study were distributed on different sub-branches with most other Chinese GoCV strains, and AH22du clustered into an independent sub-branch within the cluster. Recombination analysis predicted that HN20du might potentially recombine from the major parent of yk4 (Zhejiang Province, China, 2007) and minor parent of GD/YJ/g2 (Guangdong Province, China, 2020). To the best of our knowledge, this is the first report of GoCV in ducks from China. This broadened host spectrum of GoCVs requires attention from the waterfowl industry and researchers. |
