Abstract

A coryneform bacterium (strain 1094T) was isolated from a wound swab taken from an 89-year-old female patient. Chemotaxonomic investigations suggested that this bacterium was related to the genera Actinomyces, Arcanobacterium and Actinobaculum. Phylogenetic analysis of 16S rRNA gene sequences showed that strain 1094T was most closely related to Actinomyces europaeus CCUG 32789 AT (94.3 % similarity). Phenotypically, the isolate could be separated from its closest phylogenetic neighbours on the basis of being positive for catalase, CAMP reaction, acid phosphatase, N-acetyl-β-glucosaminidase and raffinose fermentation. Based on the data presented, it is proposed that strain 1094T should be classified in a novel species, Actinomyces hominis sp. nov. The type strain is 1094T (=CCUG 57540T =DSM 22168T).
