| Outline of Final Research Achievements |
This study aimed to develop methods for concentrating viruses in drinking water source and drinking water, mainly focusing a NanoCeram electropositive filter. Recovery test of F-specific RNA coliphage Qbeta and ColorSeed, a commercially available product containing Cryptosporidium and Giardia (oo)cysts, was conducted to develop a method for simultaneous concentration of viruses and protozoa in a single water sample. Furthermore, recovery of F-specific RNA coliphage MS2 and pepper mild mottle virus, a plant virus, using the NanoCeram electropositive filter was tested as well as methods using electronegative membrane filters. This study has successfully developed novel virus concentration methods that can be used for microbial source tracking using viruses.
