Definitions
- a first method consists of an observation of the reaction medium by nephelometry or turbidimetry, that is to say by revealing the opacity of the reaction medium.
- the present invention relates to a novel method for detecting at least one microorganism having an azoreductase activity, which may be present in a sample, comprising the steps of:
- yeasts that may be mentioned include yeasts of the following genera: Candida, Cryptococcus, Saccharomyces and Trichosporon.
- substrate or chromogenic substrate is meant a compound allowing the detection of an enzymatic or metabolic activity by means of a detectable signal directly or indirectly.
- said enzymatic or metabolic activity is that of a microorganism.
- chromogenic substrate is meant a compound allowing the detection of an enzymatic or metabolic activity by virtue of the variation of an optical signal such as a variation in absorbance and / or fluorescence.
- this substrate may be bound to a fluorescent or colored marker moiety (Orenga et al., 2009, J. Microbiol Methods, 79 (2): 139-55).
- Quencher means an element that makes it possible to reduce the fluorescence intensity of a given substance.
- a quencher can be defined as an extinguisher by absorption of excitation or emission energy.
- the quenching can then be defined as an extinction or a quenching of the excitation or emission wavelength, or by the substitution of a group on a molecule, said substitution inducing a modification of the excitation capacity of the electrons.
- group means groups or residues containing nitrogen, hydroxyl, thiols, carbon, methyl, propyl, butyl or phenyl.
- the azo compounds used in the process according to the invention can be coupled to a fluorophore whose emission wavelength or excitation wavelength is quenched by the coloration of the azo compound.
- the substrate is considered to be reduced by microorganisms when the substrate is decolorized (followed by decreased absorbance) (Decol) and / or when the fluorescence of the substrate is multiplied by 2 compared to the baseline fluorescence of a control without substrate (Fluo). Growth is indicated by Co.
- the "+” signifies good growth / discoloration / significant fluorescence increase.
- the acronym “+/-” means difficult growth.
- the symbol “-” means that there is no significant growth / discoloration / increase of fluorescence. RED indicates whether the substrate is reduced (O) or not (N).
- the reaction medium consists of:
- the substrate is considered to be reduced by the microorganisms when the fluorescence is multiplied by 2 relative to the basic fluorescence of the reaction medium. Strains that reduce the substrate and "-" strains that do not reduce the substrate are marked with a "+".
- Table VII show that the 3- (4-hydroxyphenylazo) benzoic acid sodium salt can be reduced by all the bacterial species tested and by some yeasts, whereas Tartrazine and Orange II are reduced mainly by E. faecalis.
- the "azo" molecules can be used either to detect the presence of any microbial genus, or to detect the presence of specific microorganisms, or to differentiate or characterize specific microorganisms.
