title: Arthrobacter equi sp. nov., isolated from veterinary clinical material.
abstract: A Gram-positive-staining, catalase-positive, non-spore-forming, rod-shaped bacterium, strain IMMIB L-1606(T), isolated from genital swabs of a horse, was characterized using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that the organism was related to members of the genus Arthrobacter, displaying sequence similarities of 93.5-99.1 % with the type strains of recognized species of the genus. Cell-wall analysis revealed peptidoglycan type A3α L-Lys-L-Ser-L-Thr-L-Ala. DNA-DNA hybridization data and biochemical characterization of strain IMMIB L-1606(T) enabled the isolate to be differentiated genotypically and phenotypically from phylogenetically closely related species of the genus Arthrobacter. Therefore, it is concluded that strain IMMIB L-1606(T) represents a novel species of the genus Arthrobacter, for which the name Arthrobacter equi sp. nov. is proposed. The type strain of Arthrobacter equi sp. nov. is IMMIB L-1606(T) ( = DSM 23395(T) = CCUG 59597(T)).
