摘要
目的结合不同标准和规范方法,对罗氏LightMix~Kit诺如病毒检测试剂盒(以下简称罗氏方法)进行评价。方法通过对217份门诊腹泻病人粪便标本和158份市场零售贝类样品中诺如病毒核酸平行检测,对比罗氏方法与我国SN/T 2626—2010《国境口岸诺如病毒检测方法》中逆转录-聚合酶链反应检测诺如病毒核酸方法(以下简称SN/T方法)对粪便标本与贝类样品中诺如病毒核酸检测结果的差异。结果粪便标本的罗氏方法检测阳性率为27.2%(59/217),而SN/T方法检测阳性率为17.5%(38/217),两方法结果一致率为85.7%,检出率差异有统计学意义(P<0.05)。贝类样品的罗氏方法检测阳性率为32.9%(52/158),SN/T方法检测阳性率为30.4%(48/158),两方法对诺如病毒检测结果的一致率为87.3%,检出率差异无统计学意义(P>0.05)。结论市场零售贝类样品中诺如病毒污染率较高,罗氏方法以其快速、简便、灵敏、可靠的优点值得在食品微生物检测行业推广。
Objective To compare LightMix- Kit Norovirus detection kit from Roche diagnostics company（ hereinafter referred to as＂Roche method＂） with different methods of standards and norms. Methods Two hundred and twenty-seven stool samples of diarrhea patients and 158 shellfish samples from retail markets were detected by Roche method and SN / T 2626-2010 detection of Norovirus at frontier port reverse transcription polymerase chain reaction to detect Norovirus method（ hereinafter referred to as SN / T method）. By parallel detection,the differences between the two methods were compared. Results For stool samples,about 27. 2%（ 59 /217） stool samples were positive by Roche method,while17. 5%（ 38 /217） samples were positive by SN / T method. The consistence between the two methods was 85. 7% and the detection rate of Roche methods was significantly higher than that of SN / T method（ P 0. 05）. For shellfish samples,about32. 9%（ 52 /158） shellfish samples were positives by Roche method and 30. 4%（ 48 /158） samples were positive by SN / T method. The consistence between the two methods was 87. 3% and the detection rate had no significant difference（ P 0. 05）.Conclusion The Norovirus contamination of shellfish samples from retail market was high. Roche method was rapid,simple,sensitive and reliable to detect Norovirus,and was worthy to promote in food microbiology testing industry.
