| 摘 要： | 为了解猪圆环病毒2型(PCV2)河南株的起源及遗传变异,从河南省不同临床表现的病猪中克隆了10株PCV2的全基因组,并对其进行了序列测定及分析。结果表明,河南株之间以及与中国其他地区PCV2流行株之间同源性均很高;河南株均处于欧洲分支中,提示PCV2河南株可能起源于欧洲株;河南省不同年份的PCV2中确实存在一定的基因差异,但PCV2全基因组从总体上来说遗传进化相对稳定;河南省猪群中与PCV相关的疾病不是由PCV2变异毒株引起的。

| Abstract: | To understand the genetic heterogeneity and the origin of PCV2 strains in Henan provine,complete genomes of 10 PCV2 strains were cloned and analysed from the swines with various clinical manifestation in Henan province. The result indicated that the PCV2 strains in Henan wre closely related to each other,but also to PCV2 strains from other areas of China.The PCV2 strains in Henan were included in the Europe cluster.It would be conclued that the PCV2 strains in Henan may originate from Europe PCV2.Although m... |
