A new isolate of chicken anemia virus (CAV) was designated GD-1-12. GD-1-12 was isolated from a 12-day-old commercial broiler in Guangdong province, China, in 2012. The GD-1-12 CAV caused high mortality, severe anemia, thymic atrophy, and subcutaneous hemorrhage in commercial broilers. Here, we report the complete genome sequence of GD-1-12 CAV and comparison with the complete genome sequence of another CAV that was isolated from human fecal samples in China (GenBank accession no. JQ690762). The genomes of the two CAV isolates shared high homology, although a deletion was identified by comparison. The findings from this study provide additional insights into the molecular characteristics of the CAV genomes and should advance knowledge for continuous monitoring and, perhaps, preventing the spread of the virus in chickens as well as in humans.
一株鸡贫血病毒(CAV)新分离株被命名为 GD-1-12。GD-1-12 于 2012 年从中国广东省的一只 12 日龄商品肉鸡中分离得到。GD-1-12 株 CAV 可引起商品肉鸡高死亡率、严重贫血、胸腺萎缩和皮下出血。在此,我们报道了 GD-1-12 CAV 的全基因组序列,并与中国从人粪便样本中分离的另一株 CAV 的全基因组序列进行了比较(GenBank 登录号:JQ690762)。虽然通过比较发现了一个缺失,但这两个 CAV 分离株的基因组具有高度同源性。本研究的结果为进一步了解 CAV 基因组的分子特征提供了依据,可能有助于持续监测该病毒在鸡以及人类中的传播,并可能有助于预防其传播。
