Cruoricaptor ignavus gen. nov., sp. nov., a novel bacterium of the family Flavobacteriaceae isolated from blood culture of a man with bacteraemia.

A Gram-reaction-negative bacterium, strain IMMIB L-12475(T), was isolated from blood cultures of a human with septicaemia. The yellowish orange pigmented strain contained flexirubin pigment. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strain IMMIB L-12475(T) belonged to the family Flavobacteriaceae, forming a distinct phyletic line that is distantly related (79.

Arthrobacter equi sp. nov., isolated from veterinary clinical material.

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.

Comparative chemotaxonomic and phylogenetic studies on the genus Arcanobacterium Collins et al. 1982 emend. Lehnen et al. 2006: proposal for Trueperella gen. nov. and emended description of the genus Arcanobacterium.

The results of a study comparing the chemotaxonomic characteristics and phylogenetic positions of members of the genus Arcanobacterium indicated that the genus was not monophyletic and, therefore, was in need of taxonomic revision. Phylogenetically, the genus Arcanobacterium consisted of two distinct lines; a group comprising the species Arcanobacterium haemolyticum (the type species of the genus), A. hippocoleae, A.

Auritidibacter ignavus gen. nov., sp. nov., of the family Micrococcaceae isolated from an ear swab of a man with otitis externa, transfer of the members of the family Yaniellaceae Li et al. 2008 to the family Micrococcaceae and emended description of the suborder Micrococcineae.

A Gram-reaction-positive, aerobic, catalase-positive, non-spore-forming, rod-shaped bacterium designated IMMIB L-1656(T) was isolated from an ear swab of a man and characterized using a polyphasic approach. 16S rRNA gene sequence analysis indicated that strain IMMIB L-1656(T) is related to members of the family Micrococcaceae (<95.1 % sequence similarity).

Chryseobacterium treverense sp. nov., isolated from a human clinical source.

A yellow-pigmented, Gram-reaction-negative bacterium isolated from a human clinical source was investigated using a polyphasic approach in order to clarify its taxonomic status. Comparative 16S rRNA gene sequence analysis showed that the new isolate constituted a distinct phyletic line within the genus Chryseobacterium, displaying >2.8 % sequence divergence with recognized species of this genus.
