In this study, we present an analysis of metagenome sequences obtained from a filtrate of a siphon tissue homogenate of otter clams (Lutraria rhynchaena) with swollen-siphon disease. The viral signal was mined from the metagenomic data, and a novel circular ssDNA virus was identified. Genomic features and phylogenetic analysis showed that the virus belongs to the phylum Cressdnaviricota, which consists of viruses with circular, single-stranded DNA (ssDNA) genomes. Members of this phylum have been identified in various species and in environmental samples. The newly found virus is distantly related to the currently known members of the phylum Cressdnaviricota.
在这项研究中，我们分析了来自患有肿胀虹吸管病的贻贝虹吸管组织匀浆滤液的宏基因组序列。从宏基因组数据中挖掘出病毒信号，并鉴定出一种新型的环状 ssDNA 病毒。基因组特征和系统发育分析表明，该病毒属于 Cressdnaviricota 门，该门由具有环状、单链 DNA（ssDNA）基因组的病毒组成。该门的成员已在各种物种和环境样本中被发现。新发现的病毒与目前已知的 Cressdnaviricota 门成员关系较远。
