Abstract
Laboratories working with closely related viruses need simple and cost-effective ways to rapidly validate viral stocks, detect contamination and measure the abundance of viral RNA species. Using RT-PCR and specific primers an approach for the specific detection of rhinovirus type 14 (RV14) or poliovirus type 1 (PV1) is presented. It is demonstrated that viral sequences can be amplified directly from viral stocks or from infected cells. In addition, the utility of this protocol for the detection of low levels of contaminating PV1 in RV14 stocks is shown. Further, using quantitative real-time PCR It is shown that this approach can be used for the quantitative analysis of viral RNA and replication kinetics in infected cells. This method should be useful for laboratories working with PV and RV14 and could be adapted easily for use by laboratories working with other rhinovirus and enterovirus serotypes.
