BACKGROUND
Pseudoclavibacter alba isolated from human urine in culture collection was introduced as a new species, but since then, no other reports on P. alba isolated from the environment or organisms have been published. We thus present the first case report of P. alba bacteremia.
METHODS
An 85-year-old female patient was admitted with intermittent abdominal pain and chills that had persisted for one week. She was diagnosed cholangitis with common bile duct stones.
RESULTS
Gram-positive bacteria were detected in her peripheral blood culture and identified Pseudoclavibacter species by matrix-assisted laser desorption-ionization-time of flight mass spectrometry. Pseudoclavibacter alba was identified by performing the 16S ribosomal RNA gene sequence.
CONCLUSIONS
This is the first case report of P. alba bacteremia in a patient with cholangitis.

A Gram-positive, aerobic, rod-shaped and non-motile bacterium, designated strain KP02(T), was isolated from soil from a ginseng field in Daejeon, South Korea. On the basis of 16S rRNA gene sequence similarity, this strain was shown to be related to 'Pseudoclavibacter alba' NBRC 15616 (95.5 %), 'Pseudoclavibacter faecalis' NBRC 15706 (93.9 %), Pseudoclavibacter helvolus DSM 20419(T) (93.7 %) and 'Pseudoclavibacter bifida' IAM 14848 (93.0 %). Chemotaxonomic data revealed that strain KP02(T) possessed MK-9 and MK-8 as major menaquinones and anteiso-C(15 : 0), anteiso-C(17 : 0), iso-C(16 : 0) and C(16 : 0 )as predominant fatty acids. The genomic DNA G+C content of strain KP02(T) was 64.4 mol%. The physiological and biochemical tests suggested that strain KP02(T) represents a novel species. Based on these data, strain KP02(T) (=KCTC 19255(T)=JCM 15058(T)) should be classified as the type strain of a novel Pseudoclavibacter species, for which the name Pseudoclavibacter soli sp. nov. is proposed.
