Abstract: Hantaviruses are members of the family Bunyaviridaeandare an emergingcause of diseaseworldwidewithhighlethalityin the Americas. In Brazil, thediagnosis forhantaviruses is basedonimmunologictechniquesassociatedwithconventionalRT-PCR.Anovelone-stepSYBRGreenreal-timeRT-PCRwasdevelopedfor the detectionandquantitationofAraraquarahantavirus(ARAV)and Rio Mamore hantavirus (RIOMV). Thedetectionlimitof assay was 10copies/µLofRNA in vitro transcribed of segment S. The specificity of assay was evaluatedbymeltingcurveanalysis, which showed thattheAraraquaravirusamplifiedproductgenerate dameltpeak at80.83±0.89°C without generating primer-dimersornon-specificproducts.The assay was more sensitive than conventional RT-PCR and we detected two samples undetected by conventional RT-PCR. The one-step SYBR Green real-time quantitative RT-PCR is specific, sensible and reproducible, which makes it a powerful tool in both diagnostic applications and general research of ARAVand RIOMVand possibly other Brazilian hantaviruses.
