  • Probe and a process for the detection of specific microorganisms, particularly legionellas, in environments which contain them
    Patent number: 4810644
    Abstract: The invention concerns a composition of fragments of DNA utilizable as a probe for the detection of specific micoorganism, notably Legionella, in environments which contain them. These compositions are obtained from the whole genomes of the microorganisms to be detected, after fragmentation of these genomes, particularly by using a restriction enzyme, and eliminating those sequences of the genomic DNA which are susceptible to being transcribed to ribosomal RNA.
