Listeriosis is an important bacterial zoonosis caused by the pathogenic species of the genus Listeria. The genus Listeria currently contains 17 species: L. aquatica, L. booriae, L. cornellensis, L. fleischmannii, L. floridensis, L. grandensis, L. grayi, L. innocua, L. ivanovii, L. marthii, L. monocytogenes, L. newyorkensis, L. riparia, L. rocourtiae, L. seeligeri, L. weihenstephanensis and L. welshimeri. L. dinitrificans, previously thought to be part of the Listeria genus, was reclassified into the new genus Jonesia, of which only L. monocytogenes and L. ivanovii are pathogenic. Recently, five more species have paved their way in this genus that is L. floridensis, L. aquatica, L. cornellensis, L. riparia and L. grandensis; however, these all are non-pathogenic. L. ivanovii, the other pathogenic species of genus Listeria, has been thought to be frequently associated with abortions in sheep and in cattle. Although L. ivanovii infection in humans is rare, there are reports of isolation from cases of AIDS and abortion. The remaining species are regarded as non-pathogenic. Out of these, L. monocytogenes is of major concern as it accounts for about 98% of human and 85% of animal listeriosis cases.
