The term "Listeria marthii" does not correspond to a recognized or validated species within the genus Listeria according to current taxonomic databases, including the List of Prokaryotic names with Standing in Nomenclature (LPSN), the International Journal of Systematic and Evolutionary Microbiology (IJSEM), or other authoritative microbiological resources.
Accurate information is not confirmed regarding the existence or classification of "Listeria marthii" as a distinct bacterial species. The genus Listeria includes several well-documented species, such as Listeria monocytogenes, Listeria innocua, and Listeria ivanovii, but "Listeria marthii" is not currently listed among them.
The name may represent a provisional or proposed designation that has not been formally validated, or it could be a misinterpretation or typographical variation of an existing species name. The suffix "-ii" in bacterial nomenclature typically indicates eponymous naming, often honoring a researcher or scientist (e.g., "marthii" might suggest honoring someone named Marth). However, no record exists of a named species in the genus Listeria derived from this root.
Given the lack of peer-reviewed publications or official taxonomic inclusion, "Listeria marthii" is not considered an established scientific entity. Its usage, if any, remains undocumented in reliable scientific literature.
