Actinomyces hominis sp. nov., isolated from a wound swab.
A coryneform bacterium (strain 1094(T)) 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 1094(T) was most closely related to Actinomyces europaeus CCUG 32789 A(T) (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-beta-glucosaminidase and raffinose fermentation. Based on the data presented, it is proposed that strain 1094(T) should be classified in a novel species, Actinomyces hominis sp. nov. The type strain is 1094(T) (=CCUG 57540(T) =DSM 22168(T)).
