Outline of Final Research Achievements

The objective of this study was to investigate the mechanism of acquiring free chlorine-resistance of noroviruses. As a result, it was confirmed that a population of murine norovirus acquired the relatively high resistance against free chlorine treatment by repeatedly exposing to free chlorine, owing to the dominance of free chlorine-resistant mutants in the population. Based on these results, the project leader was honored (Encouraging Award for Young Researchers) in the 55th Conference of Japanese Society of Clinical Virology.
