High positive rates of H5 and H9 might demonstrate the possibilities that AIV of H5 and H9 widely spread in wild in this period.

该时期野生鸟类中普遍出现H5和H9的高阳性率现象，可能存在H5和H9在野外的大范围传播情况。

These results suggested that the newly developed RTLAMP assay is a simple and specific method for rapid detection of H9 subtype AIV in field conditions.

结论本研究建立的RTLAMP方法简便、快速、灵敏、特异，适合在基层进行H9亚型AIV的快速检测。
