Notes: Listeria ivanovii sp. nov. [PDF]

International Journal of Systematic Bacteriology, 1984
Biochemical, genomic, and serological data indicate that strains currently referred to as Listeria monocytogenes serovar 5 are sufficiently distinct from other species of the genus Listeria to merit separate species status. It is proposed that these strains be designated Listeria ivanovii sp. nov. The type strain of L.

Listeria costaricensis sp. nov.

International Journal of Systematic and Evolutionary Microbiology, 2018
A bacterial strain isolated from a food processing drainage system in Costa Rica fulfilled the criteria as belonging to the genus Listeria, but could not be assigned to any of the known species. Phylogenetic analysis based on the 16S rRNA gene revealed highest sequence similarity with the type strain of Listeria floridensis (98.7 %).
