Abstract

The genus Listeria spp includes fifteen species, i.e. L. monocytogenes, L. ivanovii, L. innocua, L. welshimeri, L. seeligeri, L. grayi, L. marthii, L. rocourtiae, L. fleichmannii, L. weihenstephanensis, L. floridensis, L. aquatic, L. cornellensis, L. riparia and L. grandensis. Members of the genus Listeria are small Gram-positive rods sometimes arranged in short chains, ranging between 0.5 and 4 μm in diameter and between 0.5 and 2 μm in length. They are non-sporeforming and facultative anaerobic. Peritrichous flagella give them a typical tumbling motility, occurring at room temperature (20-25°C), but not at 37°C. Out of the fifteen species, L. monocytogenes is the major pathogen for humans. Very rare cases of infections due to L. ivanovii and L. seeligeri have been described.
