In 2016, tropical screech owl (Megascops choliba) (Tso) chicks were suddenly found dead in a Japanese breeding facility. We autopsied a 9-day-old Tso and discovered white spots scattered on the liver surface. Multifocal necrosis was diffused, and macrophages had infiltrated the necrotic hepatic lesions. Hepatocytes contained numerous intranuclear inclusion bodies. Immunohistochemical staining detected Adenovirus antigen only in the liver. Next, PCR and sequencing (LC536616) identified Tso Adenovirus (TsoAd). Basic Local Alignment Search Tool (BLAST) and phylogenic analyzes suggested TsoAd is an owl Aviadenovirus. Our study contributes to an improved understanding of infectious disease among captive raptors.
2016 年，日本的一个繁殖场中突然发现热带 screech 猫头鹰（Megascops choliba）（Tso）雏鸟死亡。我们对一只 9 天大的 Tso 进行了解剖，发现肝脏表面散布着白色斑点。多灶性坏死弥漫分布，巨噬细胞浸润坏死的肝病变。肝细胞内含有大量核内包涵体。免疫组化染色仅在肝脏中检测到腺病毒抗原。随后，PCR 和测序（LC536616）鉴定出 Tso 腺病毒（TsoAd）。基本局部比对搜索工具（BLAST）和系统发育分析表明，TsoAd 是一种猫头鹰 Aviadenovirus。我们的研究有助于提高对圈养猛禽传染病的认识。
