Abstract
The invention relates to a process of bacteriological analysis for differentiating the pathogenic monocytogenes species in a sample which may contain bacteria of the listeria genus, a medium for its implementation and a device for identifying Listeria monocytogenes. The process consists in bringing the sample to be analyzed into contact with an identification medium comprising a chromogenic or fluorigenic substrate capable of being hydrolyzed by glycine aminopeptidase.
Claims18
A process of bacteriological analysis in which the sample to be analyzed is brought into contact with an identification medium comprising a chromogenic or fluorigenic substrate capable of being hydrolyzed in the presence of at least one enzyme associated with the metabolism of at least one bacterial species, wherein, in order to differentiate the monocytogenes species in a sample which may contain bacteria of the Listeria genus, a glycine aminopeptidase substrate is introduced into the identification medium.
A medium for bacteriological identification, comprising a chromogenic or fluorigenic substrate capable of being hydrolyzed in the presence of at least one enzyme associated with the metabolism of at least one bacterial species, wherein, in order to differentiate the monocytogenes species in a sample to be analyzed brought into contact with the said medium and which may contain bacteria of the Listeria genus, the medium comprises a glycine aminopeptidase substrate.
