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.

首次在中国鹅群中发现鸭圆环病毒的基因异质性

鸭圆环病毒（DuCV）可感染家鸭和野鸭，阻碍其生长并抑制其免疫力，从而增加其继发感染其他病原体的可能性。本研究首次在中国的鹅中发现了2株DuCV（G221116和G210917）。为了研究这2株鹅源性DuCV的遗传特征，研究人员根据2株DuCV g的基因组序列和从GenBank数据库中检索到的参考水禽圆环病毒的基因组序列进行了多序列比对和系统发生分析。配对分析表明，2株DuCV与参考DuCV-1株和DuCV-2株的基因组序列相同度为80.95%至98.24%，与鹅圆环病毒（GoCV）的基因组序列相同度为58.04%至59.55%。系统进化分析表明，这两种DuCV属于DuCV-1和DuCV-2基因型。这些结果拓宽了我们对DuCV遗传异质性和进化的认识，并表明DuCV可在鸭和鹅之间跨宿主传播。

期刊介绍： First self-published in 1921, Poultry Science is an internationally renowned monthly journal, known as the authoritative source for a broad range of poultry information and high-caliber research. The journal plays a pivotal role in the dissemination of preeminent poultry-related knowledge across all disciplines. As of January 2020, Poultry Science will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers. An international journal, Poultry Science publishes original papers, research notes, symposium papers, and reviews of basic science as applied to poultry. This authoritative source of poultry information is consistently ranked by ISI Impact Factor as one of the top 10 agriculture, dairy and animal science journals to deliver high-caliber research. Currently it is the highest-ranked (by Impact Factor and Eigenfactor) journal dedicated to publishing poultry research. Subject areas include breeding, genetics, education, production, management, environment, health, behavior, welfare, immunology, molecular biology, metabolism, nutrition, physiology, reproduction, processing, and products.
