In total, 39 clinical cases of fowl adenoviruses (FAdV) infection in chickens (28 broiler, 7 native, and 4 layer chickens) between 2007 and 2010 in Korea were investigated. The FAdV types 4, 8b, and 11 comprised 18, 9, and 12 clinical cases, respectively. All FAdV type 4 cases showed clinical hydropericardium (HPS) lesions as well as inclusion body hepatitis (IBH), whereas all FAdV types 8b and 11 cases exhibited IBH lesions without HPS. All 3 types were detected in broiler (9-30 d old) and layer chickens (23-112 d old), whereas most native chickens (14-65 d old) were affected only by FAdV type 4. Infectious bursal disease virus and chicken infectious anemia virus were complications in 51.3% of FAdV cases, with mortalities of 55% to <0.1%. Chicken infectious anemia virus was detected in all native chicken cases. These results indicate that preventive measures against FAdV infection and immunosuppressive diseases on poultry farms should be implemented.
2007 年至 2010 年期间，韩国对 39 例感染禽腺病毒（FAdV）的鸡（28 只肉鸡、7 只本地鸡和 4 只蛋鸡）进行了调查。FAdV 型 4、8b 和 11 分别占 18、9 和 12 例临床病例。所有 FAdV 型 4 病例均表现出临床心包积水（HPS）病变和包涵体肝炎（IBH），而所有 FAdV 型 8b 和 11 病例均表现出 IBH 病变而无 HPS。所有 3 种类型均在肉鸡（9-30 日龄）和蛋鸡（23-112 日龄）中检测到，而大多数本地鸡（14-65 日龄）仅受 FAdV 型 4 感染。传染性法氏囊病病毒和鸡传染性贫血病毒在 51.3%的 FAdV 病例中是并发症，死亡率为 55%至<0.1%。所有本地鸡病例均检测到鸡传染性贫血病毒。这些结果表明，应在养殖场实施针对 FAdV 感染和免疫抑制性疾病的预防措施。
