Genetic Characterization and Antigenic Analysis of Hemagglutinin-neuraminidase Glycoprotein of Newcastle Disease Virus Isolates
新城疫分离毒HN蛋白的抗原性初步分析及分子特性研究

Twenty Newcastle disease virus(NDV)strains were isolated from diseased chicken and geese in field outbreaks during 2005 and 2006 in some regions of Jiangsu and Guangxi,and the antigenic analysis of the all NDV isolates had been done based on the reaction spectrum with a panel of monoclonal antibodies to the HN glycoprotein.The entire ORFs encoding HN protein of these NDV isolates were amplified by RT-PCR successfully,cloned and sequenced.The resultant sequences of HN genes of 13 isolates of chicken origin a...
