摘要(Abstract)：

为了解柯萨奇病毒B1型(Coxsackievirus B1,CV-B1)山东地方株的分子流行病学特征,本研究对1994年至2015年山东省急性弛缓性麻痹(Acute flaccid paralysis,AFP)监测系统、环境污水监测和无菌性脑膜炎病例标本中分离到的CV-B1病毒进行了VP1序列测定、系统发生学分析和同源性分析。共分离到CV-B1病毒53株,其中AFP监测、污水和及脑炎标本各分离到41株、4株和8株。基于VP1完整编码区序列的系统发生学分析显示CVB1山东株与国内其他分离株属于一个大的分支,该分支内无国外分离株,国外分离株构成了其他两个分支。山东株之间的VP1核苷酸同源性为84.4%~100.0%,与其他国家分离株的同源性为77.9%~85.0%。研究结果表明,中国CV-B1分离株与国外株相比有较大的遗传差异,需要加强相关手足口病病毒学监测,关注不同传播链的新的基因亚型的肠道病毒的输入。
