| Research Abstract |
In order to consider the health effects of the airborne bacteria, the bacterial concentrations and the bacterial flora in rooms and outdoor air were investigated. I analyzed the airborne bacterial communities based on the 16S rDNA sequence, and I made the classifications of airborne bacterial flora in three places (Conference room, Laboratory and Outdoor). The airborne bacterial compositions were different from each season and each place, but Staphylococcus was commonly detected in Laboratory where some people worked every day. However, the clones of species that were reported infectious case were detected less than 10% in all analyzed clones, and it was considered that there was low risk for the health effect by the airborne bacteria in these rooms.
