Abstract
A fluorescence method was developed for the direct counting of airborne microorganisms and for the examination of their interactions with other aerosol particles. The method is based on a combination of the aerosol sampling technique using a cascade impactor and the selective dyeing of the trapped microorganisms with ethidium bromide. The method enables both the total microorganism concentrations and their counts in clusters to be evaluated. The new method and the cultivation method, enabling the colony-forming units (CFU) to be determined, were compared. Based on the results obtained by the fluorescence technique, a procedure is suggested for the conversion of CFU data to bacteria and yeast concentrations.
