Abstract

Gyrovirus 3 (GyV3) has been identified in faeces from children with acute gastroenteritis. However, whether GyV3 is prevalent in poultry has not been determined to date. To the best of our knowledge, this study is the first to isolate GyV3 from commercial broiler chickens with transmissible viral proventriculitis (TVP) in China. The complete genome of the virus shares 98.4% sequence identity with the FecGy strain that causes acute gastroenteritis in children. Epidemiological investigation from 2013 to 2017 revealed that the infection rate of GyV3 reached 12.5% (42/336) in commercial broiler chickens with TVP, indicating that the infection of GyV3 was ubiquitous in chickens. The emergence of GyV3 in commercial broiler chickens should be highly concerning for public health.

摘要

禽回转病毒 3 型（GyV3）已在儿童急性肠胃炎粪便中被鉴定出来。然而，迄今为止，尚不清楚 GyV3 在禽类中是否普遍存在。据我们所知，本研究首次从中国具有传染性前囊炎（TVP）的商业肉鸡中分离出 GyV3 病毒。该病毒的完整基因组与导致儿童急性肠胃炎的 FecGy 株具有 98.4%的序列同一性。2013 年至 2017 年的流行病学调查显示，患有 TVP 的商业肉鸡中 GyV3 的感染率达到 12.5%（42/336），表明 GyV3 感染在鸡群中普遍存在。GyV3 出现在商业肉鸡中应该引起人们对公共卫生的高度关注。
