| Outline of Final Research Achievements |
BY using negatively-charged filter and magnetic nanobeads with PV receptor (PVR-MB), we could concentrate spiked PV to 5,000-fold conc. Besides this, entire capsid coding region amprification (ECRA) method and NGS analysis were highest sensitive at PV detection than any other methods. From the analysis of PV-positive Pakistani environmental samples, we could identify many kinds of PVs, including vaccine and wild strains, and other non-PV enteroviruses. It was stongly suggested that this combination method was high sensitive and time-saving PV detection tool with informative virus sequences. And this method is effective environmental PV surveillance technique without bias often found in cell culture based PV isolation.
