An unknown infectious disease in Cherry Valley ducks (Anas platyrhynchos domesticus) characterized by short beak and strong growth retardation occurred in China during 2015. The causative agent of this disease, tentatively named duck short beak and dwarfism syndrome (DSBDS), as well as the evolutionary relationships between this causative agent and all currently known avian-origin parvoviruses were clarified by virus isolation, transmission electron microscope (TEM) observation, analysis of nuclear acid type, (RT-)PCR identification, whole genome sequencing, and NS1 protein sequences-based phylogenetic analyses. The results indicated that the causative agent of DSBDS is closely related with the goose parvovirus-like virus, which is divergent from all currently known avian-origin parvoviruses and should be a novel duck parvovirus (NDPV).
2015年，中国樱桃谷鸭（Anas platyrhynchos domesticus）中出现了一种不明传染病，其特征为喙短且生长严重受阻。通过病毒分离、透射电子显微镜（TEM）观察、核酸类型分析、（RT-）PCR鉴定、全基因组测序以及基于NS1蛋白序列的系统发育分析，明确了该疾病的病原体，暂定名为鸭短喙和侏儒综合征（DSBDS），以及该病原体与所有目前已知的禽源细小病毒之间的进化关系。结果表明，DSBDS的病原体与鹅细小病毒样病毒密切相关，与所有目前已知的禽源细小病毒不同，应是一种新型鸭细小病毒（NDPV）。
