Evaluation of the TRCRtest NV-W for norovirus detection in stools by the Transcription-Reverse Transcription Concerted method
چکیده انگلیسی
A novel molecular assay, TRCRtest NV-W, based on a transcription-reverse transcription concerted reaction (TRC) for isothermal amplification and real-time detection of norovirus in stools was assessed and compared with an RT-nPCR. Archived stools positive for either different types or variants of norovirus genogroups I and II or other enteric viruses were used to assess the sensitivity and specificity of the novel assay. The TRC assay was 100% specific since it detected all the noroviruses tested and it did not display cross reactivity with other enteric viruses. When screening a collection of 387 stools with the TRC and RT-nPCR assays, the TRC displayed concordance, sensitivity, specificity, positive and negative predictive values of 96.6%, 81%, 99.7%, 98.1%, and 96.3%, respectively, after retesting the negative specimens. Additional PCRs and/or sequencing, used to understand inconsistent results between TRC and RT-nPCR, confirmed all positive results and did not reveal nucleotide variations in the TRC probe and primers binding sites. The TRC assay may be a rapid and ease of use tool for the detection of noroviruses in clinical virology laboratories even in the face of rapidly evolving noroviruses.
