A strain of haemagglutinating virus isolated by Walker and Bannister in 1953 and identified by them as "Filterable Agent" of ducks has been examined. The evidence suggests that although belonging to the Myxovirus Influenza Type A group, it possesses specific strain properties.
对1953年沃克和班尼斯特分离出并被他们鉴定为鸭“滤过性因子”的一株血凝病毒进行了研究。证据表明，尽管它属于甲型流感黏液病毒组，但具有特定的毒株特性。
