Adenoviruses have been identified in a wide variety of avian species, and in some species, they have been shown to cause disease and increase mortality. As part of an endeavor to investigate viruses associated with common terns (Sterna hirundo), a novel adenovirus was identified in fecal samples from two common terns on Gull Island, Lake Ontario, Canada. The coding-complete genome sequence of the new adenovirus is 31,094 bp, containing 28 putative genes, and this is the first adenovirus to be associated with terns. The virus was identified in two out of 13 fecal samples from tern chicks, and it was found to be most closely related to duck adenovirus 1, with the DNA polymerase sharing 58% amino acid sequence identity. Phylogenetic analysis based on DNA polymerase protein sequences showed that the new virus forms a distinct sub-branch within the atadenovirus clade and likely represents a new species in this genus.
腺病毒已在多种禽类中被发现，在某些物种中，它们已被证明会导致疾病并增加死亡率。作为一项研究与普通燕鸥（Sterna hirundo）相关病毒的努力的一部分，在加拿大安大略湖古尔岛的两只普通燕鸥的粪便样本中发现了一种新型腺病毒。这种新腺病毒的编码完整基因组序列长 31094 个碱基对，包含 28 个推定基因，这是首例与燕鸥相关的腺病毒。该病毒在 13 份幼燕鸥粪便样本中的两份中被发现，与鸭腺病毒 1 最为密切相关，其 DNA 聚合酶共享 58%的氨基酸序列同一性。基于 DNA 聚合酶蛋白序列的系统发育分析表明，该新病毒在腺相关病毒科内形成一个独特的分支，可能代表该属中的一个新种。
