Neuere Methoden zum Nachweis und zur Identifizierung luftgetragener Mikroorganismen

The detection of airborne microorganisms including selected cell constituents (e.g. allergens or endotoxins) depends on suitable methods and instruments for their collection. Furthermore, microbiological methods are necessary for their quantification and qualification. In the past these methods were largely based on the classical cultivation dependent approach. Modern molecular methods, e.g. direct staining procedures, hybridization assays with nucleic acid probes including the PCR-technology or immunological assays are promising new tools for a more sophisticated detection of bioaerosols. They allow a better detection rate, a more precise identification of certain members of the aerosol including cell constituents. With respect to speed and lower costs they are an important alternative to established detection methods.
