In multi-use facilities such as schools, periodic indoor disinfection is used as a method to reduce the probability of infection. However, little is known about the community effect of indoor microorganisms, which are the cause of infection. In this study, the change of bacterial community before and after disinfection in university classrooms was analyzed through genetic analysis. Before disinfection, the surface bacterial community decreased immediately after disinfection. After student entry and exit, the surface bacterial community increased to a level like that before disinfection. In addition, the number of airborne bacteria in the classroom without students before disinfection was higher than the number of airborne bacteria in the classroom with students after disinfection, and the number of airborne bacteria in the outside air was similar, and this was also observed in the qualitative cluster analysis using genes.
