A previously unidentified chicken parvovirus (ChPV) strain, associated with runting-stunting syndrome (RSS), is now endemic among chickens in China. To explore the genetic diversity of ChPV strains, we determined the first complete genome sequence of a novel ChPV isolate (GX-CH-PV-7) identified in chickens in Guang Xi, China, and showed moderate genome sequence similarity to reference strains. Analysis showed that the viral genome sequence is 86.4 %-93.9 % identical to those of other ChPVs. Genetic and phylogenetic analyses showed that this newly emergent GX-CH-PV-7 is closely related to Gallus gallus enteric parvovirus isolate ChPV 798 from the USA, indicating that they may share a common ancestor. The complete DNA sequence is 4612 bp long with an A+T content of 56.66 %. We determined the first complete genome sequence of a previously unidentified ChPV strain to elucidate its origin and evolutionary status.
一种先前未被鉴定出的与矮小综合征(RSS)相关的鸡细小病毒(ChPV)毒株,目前在中国鸡群中呈地方性流行。为了探究ChPV毒株的遗传多样性,我们测定了在中国广西鸡群中鉴定出的一种新型ChPV分离株(GX-CH-PV-7)的首个完整基因组序列,该序列与参考毒株的基因组序列相似度适中。分析表明,该病毒基因组序列与其他ChPV的序列一致性为86.4% - 93.9%。遗传和系统发育分析表明,这种新出现的GX-CH-PV-7与来自美国的家鸡肠道细小病毒分离株ChPV 798密切相关,这表明它们可能有共同的祖先。完整的DNA序列长4612 bp,A+T含量为56.66%。我们测定了一种先前未被鉴定出的ChPV毒株的首个完整基因组序列,以阐明其起源和进化地位。
