摘要
2株新城疫病毒ND98、ND99分别分离自发病鸡群与雏鸵鸟,ND98属于中发型毒株,ND99属于缓发型毒株。将2株分离株ND98、ND99与参考毒株F48E8、Lasota进行十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)、蛋白质转移印迹(Western-Blotting)。SDS-PAGE结果显示,ND98、ND99与F48E8、Lasota具有相似的结构蛋白:HN蛋白、F蛋白、NP蛋白与P蛋白、M蛋白;Western-Blotting试验显示,ND98与F48E8、ND99与Lasota具有相似的免疫原,ND98、ND99免疫原性存在一定的差异。
Two newcastle disease viruses(NDV) isolated from chickens and ostriches were designated as ND_(98) and ND_(99) respectively.ND_(99) was lentogenic strain and ND_(98) was mesogenic strain.The structural proteins of ND_(98)、ND_(99)、F_(48)E_8、Lasota stains were analyzed by SDS-PAGE and Western-Blotting.The result indicated that ND_(98)、ND_(99) strains had the same structural proteins as Lasota and F_(48)E_8 strains.Western-Blotting test suggested that antigen of ND_(98) and ND_(99) existed some difference,ND_(98) and F_(48)E_8 strains shared the same immunogen as ND_(99) and Lasota strains.
