  • Publication number: 20150125889
    Abstract: The present invention relates to the use of at least one azo compound for detecting at least one microorganism in a sample. More precisely, the present invention relates to a process for detecting, in a biological sample, at least one microorganism with azoreductase activity, including the steps: placing the sample in contact with a reaction medium including at least one azo compound, incubating the reaction medium, and detecting the reduction of the azo compound by the microorganism, indicating the presence of the at least one microorganism.

  • Patent number: 7407775
    Abstract: A substrate which can be used for the direct identification of pathogenic bacteria belonging to the genus Listeria by detecting an esterase activity other than Phosphatidyl Inositol-specific Phospholipase C (PI-PLC), an esterase which is specific to the species Listeria monocytogenes. The use of two substrates, one as described above and the other specific for all or some members of the genus Listeria, and a reaction medium containing such a substrate or such a combination of substrates are disclosed. An identification method which exploits such culture media is also disclosed. The invention is particularly applicable in the field of diagnosis.

  • Patent number: 7235379
    Abstract: The invention relates to a method and a medium for microbiological analysis by biochemical means involving chromogenic or fluorogenic substrates that react with enzymes (esterases) specific for the target strains. One object of the invention is to improve the sensitivity, initial translucence, stability and ease of use of such detection/identification media. For this purpose the medium according to the invention is characterized in that it is in a stable, ready-to-use liquid or gel form and in that it contains a solubilizer and stabilizer selected from fatty acid sorbitan esters, bile salts and mixtures thereof, as well as a selective activator selected from alkylsulfate salts, for example the sodium salts. The medium can comprise a solvent, for example dimethyl sulfoxide. The invention further relates to the method of obtaining this medium and to the use of products of the sodium alkylsulfate type as selective activators in such media. Application: microbiological analyses.

  • Patent number: 7217536
    Abstract: A medium for biological analysis by biochemical means involving chromogenic or fluorogenic substrates that react with enzymes (esterases and/or osidases and/or peptidases and/or sulfatases and/or phosphatases) specific for the target strains is that is in a stable, ready-to-use liquid or gel form and contains at least one emulsifying stabilizer of the fatty acid sorbitan ester/fatty acid type and at least one solvent (dimethyl sulfoxide). This medium is obtained by mixing a stock solution of esterase and/or osidase and/or peptidase and/or sulfatase and/or phosphatase substrates in the solvent, and the emulsifying stabilizer, with some of the constituents of the culture medium.
