Abstract
Airborne particles, airborne microorganisms, microorganisms fallen down on agar plates and those on the surfaces were determined in the surgical operation rooms and preceding rooms of public and private hospitals in Tokai area. Microorganisms detected in these places were classified morphologically. In general, the number of airborne particles (≥0.5μm) determined by a light scattering particle counter was in a relatively good correlation with that of airborne fungi determined by the impinger method, which was closely related to the conditions of air-conditioning of these rooms. On the contrary, no significant correlations were observed between the number of airborne particles and the number of airborne bacteria determined by three different methods.
