Duck adenovirus 3 (DuAdV-3; strain HB) was isolated and sequenced. The genome of the Muscovy-duck-origin virus contains a 54-bp insertion in pVIII, a 3-bp deletion in the overlap region of 100K, 22K, and 33K, a 42-bp deletion at the junction of ORF64 and ORF67, and a 715-bp deletion in right noncoding region of the genome. Notably, HB has a strikingly shorter right inverted terminal repeat (ITR) of 50 bp, whereas all other DuAdV-3 isolates have a 721-bp ITR. These findings demonstrate that HB is an insertion and deletion mutant of DuAdV-3.
鸭腺病毒 3(DuAdV-3;株 HB)被分离并测序。该病毒的基因组在 pVIII 中有 54 个碱基的插入,在 100K、22K 和 33K 的重叠区域有 3 个碱基的缺失,在 ORF64 和 ORF67 的连接处有 42 个碱基的缺失,在基因组的右非编码区有 715 个碱基的缺失。值得注意的是,HB 的右反向末端重复(ITR)短得惊人,只有 50 个碱基,而其他所有的 DuAdV-3 分离株的 ITR 则有 721 个碱基。这些发现表明 HB 是 DuAdV-3 的插入和缺失突变体。
