A previously undescribed facultatively anaerobic, catalase-negative, Actinomyces-like bacterium was isolated from the nose of a human. On the basis of its cellular morphology and the results of biochemical testing, the micro-organism was tentatively identified as a member of the genus Actinomyces, but it did not correspond to any currently recognized species. Comparative 16S rRNA gene sequencing studies showed the bacterium to be a hitherto unknown subline within the genus Actinomyces, displaying sequence divergence values of more than 6 % with respect to recognized species of the genus. On the basis of biochemical, molecular chemical and molecular phylogenetic evidence, it is proposed that the unknown organism, strain R2014T (=CCUG 46092T=CIP 107668T), be classified as the type strain of a novel species, Actinomyces nasicola sp. nov.

The GenBank accession number for the 16S rRNA sequence of CCUG 46092T is AJ508455.
