The invention concerns an oligonucleotide capable of being specifically hybridized with the ribosomal RNA (RNAr) or with the corresponding gene (ADNr) of the genomic species (including all the Shigella genomic species except for serotype 13 genomic species. The invention also concerns a method for detecting and displaying the bacteria of said species.

Oligonucleotide specific of the Escherichia coli species and method for detecting and displaying bacteria of this species

The invention relates to a hybridization probe for detecting the existence of bacteria in a sample. It consists of one of the two pentadecadeoxyribonucleotides of sequence (5')d - AAG GAG GTG ATC CAG (3'), (5')d - CTG GAT CAC CTC CTT (3').

Oligonucleotide probes and methods for detecting by hybridization the

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.
