Corynebacterium aquatimens sp. nov., a lipophilic Corynebacterium isolated from blood cultures of a patient with bacteremia

2012

An unknown lipophilic coryneform bacterium isolated from the blood cultures of a patient with bacteremia was characterized by phenotypic and molecular genetic methods. Chemical analysis revealed the presence of short chain mycolic acids consistent with the genus Corynebacterium. The DNA G+C content was 60.8 mol%. Comparative 16S rRNA gene sequence analysis demonstrated that the isolate represents a new subline within the genus Corynebacterium. The closely phylogenetic relative of the unknown bacterium was found to be C. tuscaniense (97.8% sequence similarity). Partial rpoB gene sequence revealed that strain IMMIB L-2475(T) exhibited 13.5% sequence divergence with C. tuscaniense. The unknown…

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

2012

Abstract 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 (79.1–89.4% sequence similarity) to described genera of this family. Membership to the family was confirmed by a fatty acid profile consisting of branched-chain and 3-hydroxy fatty acids with major amounts of iso-C 17:0 3-OH and iso-C 15:0 , by the presence of menaquinone MK-6 as the only respiratory quin…

Canibacter oris gen. nov., sp. nov., isolated from an infected human wound.

2014

A facultatively anaerobic, Gram-reaction-positive, catalase- and oxidase-negative, rod-shaped bacterium isolated from an infected human wound caused by a dog bite was characterized by phenotypic and molecular genetic methods. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain IMMIB Q2029717T was a member of the order Micrococcales of the class Actinobacteria , displaying 91.6 % to 96 % sequence similarity with members of the family Microbacteriaceae . Phylogentic trees generated by different algorithms indicated that the strain forms an independent phylogenetic line of descent that consistently clustered proximal to the base of the genus Leucobacter .

Subtercola boreus gen. nov., sp. nov. and Subtercola frigoramans sp. nov., two new psychrophilic actinobacteria isolated from boreal groundwater.

2000

Psychrophilic actinobacterial isolates from permanently cold groundwater in Finland were characterized using a polyphasic approach. Growth on agar plates was observed at temperatures down to -2 degrees C, with an optimum at 15-17 degrees C, but no growth was observed at 30 degrees C. The peptidoglycan type was B2y and the characteristic diamino acid was diaminobutyric acid. The cell wall sugars of strain K265T were rhamnose, ribose, xylose and mannose and those of strain K300T were glucose, rhamnose and xylose. The polar lipids included phosphatidylglycerol, diphosphatidylglycerol, one unknown phospholipid and two glycolipids. The main whole-cell fatty acids were 12-methyltetradecanoic acid…
