| Outline of Final Research Achievements |
In mouse noroviruses used as surrogate model viruses for human noroviruses, we found that disinfection with free chlorine and alkaline treatment caused adaptive evolution in which the mouse norovirus population acquired disinfection resistance. These results suggest that the use of virus strains with higher susceptibility to disinfection (i.e., lower disinfection resistance) in disinfection tests performed in sewage treatment is likely to introduce bias in the assessment of viral strain inactivation efficiency. This finding indicates the need to use less susceptible virus strains in disinfection testing.
