Abstract
The invention relates to a method for the rapid detection and enumeration of microorganisms. The spectroscopic detection is carried out, after brief incubation of the sample to be tested, by the detection of the growth of microcolonies, which is not yet detectable with the naked eye, on a solid culture plate following direct transfer of said microcolonies to a sample carrier by special impression techniques; the detection itself is carried out by recording the spectra of all, or of a representative number, of the impressions, using an IR microscope. It is not only possible to make statements with regard to the number of microorganisms in the sample but the high information content of the spectra can also be used for demanding microbiological differentiation work down to species identification.
