ABSTRACT: Duck circovirus (DuCV) can infect domestic and wild ducks, retarding growth and suppressing immunity, thereby increasing the possibility of secondary infection by other pathogens. In this study, for the first time, 2 DuCV strains (G221116 and G210917) were identified in geese from China. To study the genetic characteristics of the 2 goose-originated DuCVs, multiple sequence alignment and phylogenetic analyses were perforemed according to genome sequences of 2 DuCV strains g and reference waterfowl circoviruses retrieved from the GenBank database. Pairwise analysis showed that the genome sequence identities between the 2 DuCVs with reference DuCV-1 and DuCV-2 strains were 80.95% to 98.24%, and 58.04% to 59.55% with Goose circovirus (GoCV). Phylogenetic analysis showed that the 2 DuCVs belonged to DuCV-1 and DuCV-2 genotypes. These results broaden our understanding of the genetic heterogeneity and evolution of DuCV and suggest trans-host transmission of DuCV between ducks and geese.
