[New species of the genus Listeria: Listeria seeligeri].
Listeria seeligeri is a recently described species which shares 28% to 1% DNA relatedness with the other species of the genus Listeria. G + C% content of the type strain is 36. Peptidoglycan type (variation A1 gamma) as well as teichoic acids are identical to those found in L. monocytogenes. L. seeligeri can be easily distinguished from the other species using the following markers: hemolysis (CAMP-tests with Staphylococcus aureus and Rhodococcus equi) and acid production from D-xylose, L-rhamnose and alpha-methyl-D-mannoside. No specific antigen allow to characterize L. seeligeri strains which belong to serogroups 1/2 (81%), 4 (12%) and 6 (6%). 85% of these strains proved to be phage typable. So far, more than 100 strains were isolated, mainly in Europe, from environment and animal healthy carriers. Unless one case of meningitis in human, strains of this species are experimentally non virulent.
