摘要：Introduction and objective. The presence of airborne bacteria in hospital environments is of great concern becauseof their potential role as a source of hospital-acquired infections (HAI). The aim of this study was the determination andcomparison of the concentration of airborne bacteria in different wards of four educational hospitals, and evaluation ofwhether particle counting could be predictive of airborne bacterial concentration in different wards of a hospital.Materials and method. The study was performed in an operating theatre (OT), intensive care unit (ICU), surgery ward (SW)and internal medicine (IM) ward of four educational hospitals in Isfahan, Iran. A total of 80 samples were analyzed for thepresence of airborne bacteria and particle levels.Results. The average level of bacteria ranged from 75–1194 CFU/m3. Mean particle levels were higher than class 100,000cleanrooms in all wards. A significant correlation was observed between the numbers of 1–5 μm particles and levels ofairborne bacteria in operating theatres and ICUs. The results showed that factors which may influence the airborne bacteriallevel in hospital environments should be properly managed to minimize the risk of HAIs especially in operating theaters.Conclusions. Microbial air contamination of hospital settings should be performed by the monitoring of airborne bacteria,but particle counting could be considered as a good operative method for the continuous monitoring of air quality inoperating theaters and ICUs where higher risks of infection are suspected.
