Development of real-time PCR to detect oral vaccine-like poliovirus and its application to environmental surveillance

When real-time PCR was applied to environmental surveillance, the overall agreement rates between real-time PCR and the cell culture were 83.3% for all serotypes. Since real-time PCR has the advantages of rapid detection of viruses and minimum requirement of sampling volume as compared with ordinary cell culture, it is suitable to monitor oral poliovirus vaccine-like poliovirus in the environment, especially in areas where an oral vaccine is being replaced by an inactivated vaccine.
