Abstract

In 2017, an H7N8 avian influenza virus (AIV) was isolated from a domestic duck from a farm in Central China. Sequences analysis showed that this strain received its genes from H7, H1, H2, H3, H5, and H6 AIVs of domestic poultry and wild birds in Asia. It exhibited low pathogenicity in chickens and mild pathogenicity in mice. These results suggest the importance of continued surveillance of the H7N8 virus to better understand the ecology and evolution of the AIVs in poultry and wild birds and the potential threat to human health.

摘要

2017年，从中国中部一个农场的一只家鸭中分离出一株H7N8禽流感病毒（AIV）。序列分析表明，该毒株的基因来自亚洲家禽和野鸟的H7、H1、H2、H3、H5和H6禽流感病毒。它在鸡中表现出低致病性，在小鼠中表现出轻度致病性。这些结果表明持续监测H7N8病毒对于更好地了解家禽和野鸟中禽流感病毒的生态学和进化以及对人类健康的潜在威胁具有重要意义。
