Studies on the susceptibility of terrestrial wild bird and the propagation to highly pathogenic avian influenza virus

本研究假设高致病性禽流感病毒的多种感染途径进行了野外感染试验，结果表明：（1）病毒通过湖水从感染的野生水禽传播到陆地野鸟;（2）感染的陆地野鸟侵入鸡舍，病毒通过与鸡接触传播;（3）陆地野鸟之间，这些结果支持了预防陆生野生鸟类入侵鸡舍对高致病性禽流感禽流感的防疫非常重要的观点。

In this study, the infection experiment supposing various infection routes of highly pathogenic avian influenza virus in field was conducted.The results obtained showed that (1) the virus spreads from infected wild waterfowl to terrestrial wild bird through the water of lake(2) the infected terrestrial wild bird invades in a henhouse, and a virus spreads by contacting with a chickenbut (3) between terrestrial wild birds, it is hard to consider a possibility that infection will spread one after another.These results support the notion that the invasion preventive measures of the terrestrial wild bird into a henhouse are very important on the epidemic prevention of highly pathogenic avian influenza avian influenza.
