Papillomaviruses (family ) are non-enveloped, circular, double-stranded DNA viruses known to infect squamous and mucosal epithelial cells. In the family there are 53 genera and 133 viral species whose members infect a variety of mammalian, avian, reptilian, and fish species. Within the Antarctic context, papillomaviruses (PVs) have been identified in Adélie penguins ( 2 PVs), Weddell seals ( 7 PVs), and emerald notothen ( 1 PV) in McMurdo Sound and Ross Island in eastern Antarctica. Here we identified 13 diverse PVs from buccal swabs of Antarctic fur seals ( 2 PVs) and leopard seal ( 3 PVs) in western Antarctica (Antarctic Peninsula), and vaginal and nasal swabs of Weddell seals (8 PVs) in McMurdo Sound. These PV genomes group into four genera representing 11 new papillomavirus types, of which five are from two Antarctic fur seals and a leopard seal and six from Weddell seals.

从南极海狗、豹海豹和威德尔海豹中鉴定出多种乳头瘤病毒

乳头瘤病毒（科）是无包膜、环状、双链 DNA 病毒，已知可感染鳞状和粘膜上皮细胞。该科有 53 属、133 种病毒，其成员感染多种哺乳动物、鸟类、爬行动物和鱼类。在南极地区，已在南极洲东部麦克默多海峡和罗斯岛的阿德利企鹅（2 个 PV）、威德尔海豹（7 个 PV）和翡翠诺托森（1 个 PV）中发现了乳头瘤病毒（PV）。在这里，我们从南极洲西部（南极半岛）的南极毛皮海豹（2 个 PV）和豹海豹（3 个 PV）的口腔拭子以及麦克默多海峡的威德尔海豹（8 个 PV）的阴道和鼻拭子中鉴定出了 13 种不同的 PV。这些PV基因组分为四个属，代表11种新的乳头状瘤病毒类型，其中五种来自两只南极海狗和一只豹海豹，六种来自威德尔海豹。
