【摘要】：本文旨在鉴定福建省2014~2015年冬季导致病毒性胃肠炎暴发的病原体,并对病原体进行分子特征研究。收集福建省2014~2015年胃肠炎暴发期间急性病例的标本,开展诺如病毒检测并对衣壳蛋白基因片段进行分子特征分析。共检测3起暴发疫情标本31份,检出GⅡ型诺如病毒阳性标本17份。测序结果证实有13份标本为诺如病毒GⅡ.17新变异株,与2014年日本毒株Kawasaki 323同源性最高,在系统进化上形成一个新的独立的分枝,有别于近年来本地散发流行及全球暴发流行的优势基因型GⅡ.4。是福建省内首次检出诺如病毒GⅡ.17,并引起病毒性胃肠炎暴发。
[Abstract]:The purpose of this paper is to identify the pathogen that caused the outbreak of viral gastroenteritis in Fujian Province in the winter of 2014-2015, and to study the molecular characteristics of the pathogen. The samples of acute cases of gastroenteritis during 2014-2015 in Fujian Province were collected, and the norovirus detection was carried out and the molecular characteristics of capsid protein gene fragments were analyzed. A total of 31 specimens of 3 outbreaks were detected and 17 positive specimens of G 鈪，
