The recent isolation of viscerotropic velogenic strains of Newcastle disease virus having a thermosensitive hemagglutinin and of a lentogenic strain with an unusually thermostable hemagglutinin confirmed that virulence for chickens was not related to the thermostability and could be used as a marker for strains in epizootiologic investigations.
最近分离出具有热敏感血凝素的新城疫病毒嗜内脏速发型毒株以及具有异常耐热血凝素的缓发型毒株,这证实了对鸡的毒力与热稳定性无关,并且在流行病学调查中可将其用作毒株的一个标记。
