ABSTRACT:
A substrate which can be used for the direct identification of pathogenic bacteria belonging to the genusListeriaby detecting an esterase activity other than Phosphatidyl Inositol-specific Phospholipase C (PI-PLC), an esterase which is specific to the speciesListeria monocytogenes. The use of two substrates, one as described above and the other specific for all or some members of the genusListeria, 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.
