Abstract: 
A polyphasic taxonomic study was performed on an unidentified Arcanobacterium-like Gram-stain-positive bacterium isolated from otitis externa of a dog. Comparative 16S rRNA gene sequencing showed that the bacterium belonged to the genus Arcanobacterium and was most closely related to the type strains of Arcanobacterium haemolyticum (97.2 %), Arcanobacterium hippocoleae (96.5 %) and Arcanobacterium phocae (96.4 %). The presence of the major menaquinone MK-9(H(4)) supported the affiliation of this strain to the genus Arcanobacterium. The polar lipid profile contained the major lipids phosphatidylcholine, diphosphatidylglycerol, phosphatidylinositol mannoside and an unidentified phospholipid (PL2). Major fatty acids were C(14 : 0), C(16 : 0), C(18 : 0), C(18 : 1)ω9c and C(18 : 2)ω6,9c/anteiso-C(18 : 0) (detected as a summed feature). C(10 : 0) and C(12 : 0) were present in minor amounts. The results of physiological and biochemical testing clearly distinguished the unknown bacterium from other species of the genus Arcanobacterium. Based on these tests, it is proposed that the unknown bacterium should be classified in the novel species Arcanobacterium canis sp. nov. The type strain of Arcanobacterium canis is P6775(T) (= CCM 7958(T) = CCUG 61573(T) = CIP 110339(T)). An emended description of the genus Arcanobacterium is also provided.
