一株新城疫基因Ⅶ型病毒株的分子生物学鉴定

Biological Identification of Gane Ⅶ of Newcastie Disease Uirws

从鹤壁某患病鸡群中分离到一株病毒（ＨＢ９７），该病毒用单克隆抗体鉴定为新城疫强毒株。但其抗原性与新城疫Ｆ４８Ｅ８株有明显差异。经过对Ｆ基因的扩增、克隆、测序及与其他毒株的 Ｆ基因序列比较，表明该毒株为新城疫基因Ⅶ型。这为更好地控制和预防新城疫提供了依据。

One virase isolate was obtained from a chicken flock in Hebi. It was identified by monoclonal antibodie. It is a virulent virws of Newcastle disease virws but it differs form F48Eg Strain. Awplification, cloning and Sequening of Fusfon gene of the isolate was identified. It shows that the isolate is a gene Ⅶ of Newcastle diseas Vinws.
