Transfer of Listeria dentrificans to a New Genus, Jonesia gen. nov., as Jonesia denitrificans comb. nov.

Abstract
The 16S ribosomal ribonucleic acid catalog of Listeria denitrificans CIP 55134T was determined. The results confirmed previous evidence that this organism is not a member of the genus Listeria. Whereas L. monocytogenes is a member of the Bacillus-Clostridium subdivision of gram-positive bacteria, L. denitrificans is phylogenetically related to members of one of the several subbranches of the actinomycetes subdivision, defined by the genera Actinomycetes, Arthrobacter, Micrococcus, Cellulomonas, Stomatococcus, and Promicromonospora and allied taxa. The low similarity coefficients found between L. denitrificans and these genera, together with previous described chemotaxonomic properties, indicate that this species should be transferred to a new genus, Jonesia gen. nov., as Jonesia denitrificans comb. nov.
