【摘要】:目的检测海口市售牡蛎感染诺如病毒的情况,为诺如病毒防治提供参考。方法 2015年9月-2016年5月,在海口市随机抽样,采集牡蛎标本,提取病毒核酸,应用实时荧光定量PCR检测诺如病毒核酸,进行诺如病毒GⅠ群或GⅡ群基因分型。以脊髓灰质炎疫苗中的病毒作为标准品检测病毒的回收率。结果牡蛎标本220份,分别来自广东湛江、广西北海、海南海口和儋州。经实时荧光定量PCR检测6份标本诺如病毒核酸阳性,阳性率为2.73%;其中4份标本同时携带诺如病毒GⅠ群和GⅡ群,2份仅GⅡ群阳性。冬季和春季采集的标本阳性率分别为5.88%(4/68)和3.64%(2/55)。广东湛江和海南海口的牡蛎诺如病毒阳性率分别为9.80%(5/51)和1.28%(1/78),其他两地的牡蛎未检出诺如病毒。以脊髓灰质炎疫苗作为标准品验证诺如病毒的平均回收率为11.46%。结论海口市市售牡蛎受到诺如病毒污染,有关部门应采取相应措施,加强市售海产品管理,降低人群感染诺和病毒的风险。
