However, the absence of cytopathologic effects (CPE) in many of the cell lines used commonly makes it difficult to confirm RV growth. In this study, two assays amplifying RV cDNA were developed and validated in order to confirm and genotype RV isolates after cell culture. A SYBR Green I\u2010based real\u2010time PCR (Rtime\u2010SGE317) was established for initial rapid detection of RV in Vero cells and a nested PCR (PCR\u2010E860) was used for amplifying further the 739 nt window of the E1 gene for the identification of RV genotype as recommended by the WHO. Sensitivities of the two assays were evaluated using eight RV isolates, two from infants with the congenital rubella syndrome (CRS) and six from patients with acute rubella. All the isolates had cycle threshold (C<jats:sub>t<\/jats:sub>) values &lt;37 after the third passage, which is recommended as the cut\u2010off for the confirmation of a viable RV isolate. Phylogenetic analysis based on the 739 nt window generated by the PCR\u2010E860 showed that the eight RV isolates belonged to genotypes 1E, 1G, and 2B. The Rtime\u2010SGE317 assay can be carried out in local public health laboratories, which would extend the molecular surveillance of rubella and contribute to the WHO goal of eradicating rubella worldwide.
