Three cycloviruses (genus Cyclovirus, family Circoviridae) were recovered from a dragonfly (Odonata: Anisoptera) captured in Fuzhou, China. The three cycloviruses, named dragonfly associated cyclovirus 9, 10 and 11 (DfCyV-9, -10, -11), respectively, show 56.1-79.6% genome-wide identity to known cycloviruses and 61.6-65.1% among themselves. Thus, according to the current species demarcation criteria, they represent three novel cycloviruses. Notably, DfCyV-10 has a predicted replication-associated protein (Rep) that is most similar to that of bat associated cyclovirus 2 (BatACyV-2), a cyclovirus discovered in China, with 79.4% amino acid sequence identity, but a putative capsid protein (Cp) most similar to that of BatACyV-10, a cyclovirus discovered in Brazil, with 71.7% amino acid sequence identity. These data are useful for understanding the diversity and evolution of cycloviruses, especially those found in insects.
从中国福州捕获的一只蜻蜓（蜻蜓目：差翅亚目）中分离出三种环病毒（环病毒属，圆环病毒科）。这三种环病毒分别命名为蜻蜓相关环病毒9、10和11（DfCyV-9、-10、-11），它们与已知环病毒的全基因组同一性为56.1-79.6%，彼此之间的同一性为61.6-65.1%。因此，根据目前的物种划分标准，它们代表三种新型环病毒。值得注意的是，DfCyV-10具有一个预测的复制相关蛋白（Rep），与在中国发现的蝙蝠相关环病毒2（BatACyV-2）的最为相似，氨基酸序列同一性为79.4%，但其假定的衣壳蛋白（Cp）与在巴西发现的环病毒BatACyV-10的最为相似，氨基酸序列同一性为71.7%。这些数据有助于理解环病毒的多样性和进化，尤其是在昆虫中发现的环病毒。
