Non-fermenting Gram-negative bacteria are problematic in clinical locations, being one of the most prevalent causes of nosocomial infections. Many of these non-fermenting Gram-negative bacteria are opportunistic pathogens that affect patients that are suffering with underlying medical conditions and diseases. Brevundimonas spp., in particular Brevundimonas diminuta and Brevundimonas vesicularis, are a genus of non-fermenting Gram-negative bacteria considered of minor clinical importance. Forty-nine separate instances of infection relating to Brevundimonas spp were found in the scientific literature along with two pseudo-infections. The majority of these instances were infection with Brevundimonas vesicularis (thirty-five cases – 71%). The major condition associated with Brevundimonas spp infection was bacteraemia with seventeen individual cases/outbreaks (35%). This review identified forty-nine examples of Brevundimonas spp. infections have been discussed in the literature. These findings indicate that infection review programs should consider investigation of possible Brevundimonas spp outbreaks if these bacteria are clinically isolated in more than one patient.

“…Calculations were carried out according to Mesbah et al , (1989), with non-methylated lambda-phage DNA (Sigma) as a standard. Amplification of the 16S rRNA gene and sequencing was done as described previously (Abraham et al , 2010). The phylogenetic position of strain MCS 33 T was determined by analysis of the 16S rRNA gene sequence (Abraham et al , 1999) using the software clustal w (Thompson et al , 1997).…”

Cauliform bacteria are prosthecate bacteria often specialized for oligotrophic environments. A polyphasic approach, comprising 16S rRNA gene sequencing, lipid analysis and salt tolerance characterizations, was used to clarify the taxonomy of one isolate, strain MCS 33T, obtained from above the hot water plume of a deep-sea hydrothermal vent near Vancouver island, Canada. Cells contained no detectable phospholipids or sulpholipids, but did contain 1,2-di-O-acyl-3-O-α-d-glucopyranosylglycerol, 1,2-di-O-acyl-3-O-α-d-glucopyranuronosylglycerol and the novel lipid 1,2-di-O-acyl-3-[O-α-d-glucopyranuronosyl]glycerol-6′-N-glycine. It is assumed that the various glucoronosyl lipids are replacing, at least partially, the phospholipids in their various tasks in the cell cycle. The G+C content of the genomic DNA of strain MCS 33T was 62.8 mol%, and Q10 was the predominant respiratory ubiquinone. The 16S rRNA gene sequence of this chemoheterotrophic, aerobic, moderately halophilic strain showed only a low similarity of 94.4 % to that of Oceanicaulis alexandrii C116-18T, and both strains also differed based on their lipids. Although the novel strain was isolated from seawater sampled near a hydrothermal vent, its optimum temperature for growth was 30 °C. The main cellular fatty acids were C18 : 1ω7c, C18 : 0 and the unknown fatty acid ECL 11.798, and the main hydroxy fatty acid was C12 : 0 3-OH. The strain is proposed to represent a novel species of a new genus, Glycocaulis abyssi gen. nov., sp. nov. The type strain of the type species is MCS 33T ( = LMG 27140T = CCUG 62981T).

“…Subsequently, several Caulobacter species and subspecies were transferred to the genus Brevundimonas as Brevundimonas alba , B. aurantiaca , B. bacteroides , B. intermedia , B. subvibrioides and B. variabilis (Abraham et al , 1999). Additionally, over a dozen Brevundimonas species, B. nasdae (Li et al , 2004), B. mediterranea (Fritz et al , 2005), B. kwangchunensis (Yoon et al , 2006a), B. terrae (Yoon et al , 2006b), B. aveniformis (Ryu et al , 2007), B. lenta (Yoon et al , 2007), B. naejangsanensis , B. bullata (Kang et al , 2009), B. basaltis (Choi et al , 2010), B. halotolerans , B. poindexterae , B. staleyi (Abraham et al , 2010), B. vancanneytii (Estrela & Abraham, 2010) and B. viscosa (Wang et al , 2012), have been described or reclassified. In this study, we report on a novel Brevundimonas -like dimorphic prosthecate bacterial strain, TAR-001 T , which was isolated from a deep-subsea floor sediment sample at a depth of 11 m below the sea floor (mbsf) off the Shimokita Peninsula of Japan in the north-western Pacific Ocean (Site C9001: 1180 m water depth).…”

“…1,2-Di- O -acyl-3- O -α- d -glucopyranuronosyl glycerol (MGDOx), phosphatidylglycerol (PG), 1,2-di- O -acyl-3- O -α- d -glucopyranosyl glycerol (MGD) and 1,2-di- O -acyl-3- O -[ d -glucopyranosyl-(1→4)-α- d -glucopyranuronosyl]glycerol (DGL) were the major polar lipid constitutions (Table S2). The cellular fatty acid profile of strain TAR-001 T consisted of straight-chain unsaturated fatty acids and saturated fatty acids, and small amounts of hydroxy fatty acids, a typical pattern for the genus Brevundimonas (Abraham et al , 1999, 2010; Li et al , 2004; Fritz et al , 2005; Yoon et al , 2006a, b, 2007; Ryu et al , 2007; Kang et al , 2009; Choi et al , 2010; Wang et al , 2012).

Brevundimonas abyssalis sp. nov., a dimorphic prosthecate bacterium isolated from deep-subsea floor sediment A novel Gram-negative, aerobic, psychrotolerant, alkali-tolerant, heterotrophic and dimorphic prosthecate bacterium, designated strain TAR-001 T , was isolated from deep-sea floor sediment in Japan. Cells of this strain had a dimorphic life cycle and developed an adhesive stalk at a site not coincident with the centre of the cell pole, and the other type of cell, a swarm cell, had a polar flagellum. Colonies were glossy, viscous and yellowish-white in colour. The temperature, pH and salt concentration range for growth were 2-41 6C, pH 6.5-10.0 and 1-4 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences confirmed that strain TAR-001 T belongs to the family Caulobacteraceae of the class Alphaproteobacteria, and lies between the genus Brevundimonas and the genus Caulobacter. Levels of similarity between the 16S rRNA gene sequence of strain TAR-001 T and those of the type strains of Brevundimonas species were 93.3-95.7 %; highest sequence similarity was with the type strain of Brevundimonas diminuta. Levels of sequence similarity between those of the type strains of Caulobacter species were 94.9-96.0 %; highest sequence similarity was with the type strain of Caulobacter mirabilis. The G+C content of strain TAR-001 T was 67.6 mol%. Q-10 was the major respiratory isoprenoid quinone. The major fatty acids were C18 : 1v7c and C16 : 0, and the presence of 1,2-di-O-acyl-3-O-[D-glucopyranosyl-(1A4)-a-D-glucopyranuronosyl]glycerol suggests strain TAR-001 T is more closely to the genus Brevundimonas than to the genus Caulobacter. The mean DNA-DNA hybridization levels between strain TAR-001 T and the type strains of two species of the genus Brevundimonas were higher than that of the genus Caulobacter. On the basis of polyphasic biological features and the 16S rRNA gene sequence comparison presented here, strain TAR-001 T is considered to represent a novel species of the genus Brevundimonas, for which the name Brevundimonas abyssalis sp. nov. is proposed; the type strain is TAR-001 T (5JCM 18150 T 5CECT 8073 T ).Dimorphic prosthecate bacteria (DPB) show a characteristic reproduction event resulting in asymmetrical cells. These bacteria, which are typically aquatic chemo-organotrophs, produce two atypical cells; one is called a stalked cell possessing a prostheca with a holdfast at its distal tip, and the other is a motile cell with a polar flagellum, which is called a swarmer cell (Poindexter, 1981(Poindexter, , 1999Schmidt, 1981). Daughter cells, which bear a single flagellum at the opposite cell pole, arise by asymmetrical division, and shed the flagellum and differentiate into stalked cells (Poindexter, 1999;Garrity et al., 2005). On the basis of the morphology of the reproductive mode, there are two main types of DPB: one is the caulobacteria, which include the genera Caulobacter, Brevundimonas, Asticcacaulis, Phenylobacterium, Maricaulis and Woodsholea, and the other is the hyphomicrobia, which inc...
