| Outline of Final Research Achievements |
Recently, many novel polyomaviruses have been identified as a candidate pathogenic virus that is responsible for particular diseases in immune compromised patients. This study has tried to isolate novel viruses responsible for a disease by rolling cycle amplification which can strongly amplify viral circular genomic DNA. Using test samples, we set up a condition where we can amplify a very small amount of circular DNA from total DNA sample. Then, we tested series of healthy- and disease- derived samples to amplify circular DNA. Most of amplified DNA are either artifacts or mitochondrial DNA. Skin samples provide amplification of MCV polyomavirus, that is consistent with previous published reports. However, we do not find a novel polyomavirus. Origin unknown circular DNA are also found, which is a clear outcome of this study, in spit of few information of pathogenicity.
