In this study, a novel parvovirus (gyb-MR02/2015/HUN, MT580795) was detected in barn owls (Tyto alba) and genetically characterized using viral metagenomics and PCR methods. The NS1 and VP1 proteins of gyb-MR02/2015/HUN share only 45.4% and 50.1% amino acid sequence identity, respectively, to the corresponding proteins of peafowl parvovirus 2 (MK988620), the closest relative. Out of 11 faecal specimens from owls (six from little owls, three from barn owls, and two from long-eared owls), two barn owl samples were positive for the novel parvovirus, which is distantly related to members of the recently established genus Chaphamaparvovirus in the subfamily Hamaparvovirinae. Systematic investigation is necessary to explore the diversity of parvoviruses.
在这项研究中，通过病毒宏基因组学和 PCR 方法，在仓鸮（Tyto alba）中检测到一种新的微小病毒（gyb-MR02/2015/HUN，MT580795），并对其进行了基因特征分析。gyb-MR02/2015/HUN 的 NS1 和 VP1 蛋白分别与亲缘关系最近的孔雀微小病毒 2（MK988620，NC_020605）的相应蛋白的氨基酸序列同一性分别为 45.4%和 50.1%。在来自 11 份猫头鹰粪便样本（6 份来自小猫头鹰，3 份来自仓鸮，2 份来自长耳鸮）中，有 2 份仓鸮样本检测到新型微小病毒呈阳性，该病毒与最近在 Hamaparvovirinae 亚科中建立的 Chaphamaparvovirus 属的成员关系较远。有必要进行系统调查，以探索微小病毒的多样性。
