“…Additionally, D. chelonae shares a 96.6% 16S rRNA gene sequence similarity with K. limosa, indicating a closer relationship to K. limosa than to D. congolensis (94.9% similarity). The necessity of phylogenetic and chemotaxonomic studies for the assignment of D. chelonae at the genus level has previously been raised (Stackebrandt, 2006;Stackebrandt and Schumann, 2000).…”

“…It is also interesting that Demetria terragena DSM 11295 T , a representative of the third genus currently classified in the family Dermacoccaceae (Stackebrandt & Schumann, 2000), was reported to contain branched-chain, though not unsaturated, fatty acids (Groth et al, 1997). Moreover, it is clearly of note that representatives of all of the genera presently grouped in the family Dermacoccaceae synthesize significant quantities of branched-chain fatty acids, whereas these components are absent from members of the closely related family Dermatophilaceae (McNabb et al, 1997;Liu et al, 2002;Stackebrandt, 2003), although there have been reports of branched-chain fatty acids in some strains of Dermatophilus congolensis (Hasegawa et al, 1979;Dusch et al, 1994). The families Dermacoccaceae and Dermatophilaceae were defined on the basis of signature nucleotides in their 16S rRNA gene sequences (Stackebrandt & Schumann, 2000); hence, the fatty acid data provide additional evidence for the distinction of these taxa.…”

The taxonomic status of an actinobacterial strain isolated from Mariana Trench sediment was determined using a polyphasic taxonomic approach. The present study was designed to establish the taxonomic status of an actinobacterial strain, isolate MT1.1 T , recovered from sediment collected from the Challenger Deep in the Mariana Trench and considered to be closely related to the genus Dermacoccus using 16S rRNA gene sequence data (Pathom-aree et al., 2006). The strain was the subject of a polyphasic taxonomic study, which showed that it merited recognition within a novel species of Dermacoccus. Sediment was taken from the Mariana Trench (Challenger Deep; 11 u 19?9119 N 142 u 12?3729 E) at a depth of 10 898 m using sterilized mud samplers and the remotely operated submersible Kaiko (Kato et al., 1997). The sample (2 ml), which was collected on 21 May 1998 during dive number 74, was transported to the UK in an insulated container at 4 u C and then stored at 220 u C. Strain MT1.1 T was isolated from a suspension of the sediment sample used to inoculate a raffinose-histidine agar plate (Vickers et al., 1984) supplemented with cycloheximide and nystatin. It was maintained on glucose-yeast extract agar plates (Gordon & Mihm, 1962) at room temperature and as glycerol suspensions (20 %, v/v) at 220 u C.Isolation of chromosomal DNA, PCR amplification and direct sequencing of the purified products of strain MT1.1 T were carried out as described previously (Kim et al., 2000). The amplified 16S rRNA gene sequence (1443 nt) was aligned manually with corresponding sequences of representatives of genera classified in the suborder Micrococcineae that had been retrieved from DDBJ/EMBL/GenBank using the program PHYDIT (available at http://plaza.snu.ac.kr/ jchun/phydit/). Phylogenetic trees were inferred using the least-squares (Fitch & Margoliash, 1967), maximumlikelihood (Felsenstein, 1981), maximum-parsimony (Kluge & Farris, 1969) and neighbour-joining (Saitou & Nei, 1987) tree-making algorithms from the PHYLIP suite of programs (Felsenstein, 1993). Evolutionary distance matrices for the least-squares and neighbour-joining methods were generated after Jukes & Cantor (1969). Stability of the resultant 3Present address:

Der.ma.to.phi'lus. Gr. n. derma ‐atos skin; Gr. adj. philos loving; N.L. masc. n. Dermatophilus skin loving. Actinobacteria / Actinobacteria / Micrococcales / Dermatophilaceae / Dermatophilus Aerial mycelium develops in atmospheres containing added CO 2 . Substrate mycelium consists of long tapering filaments , branching laterally at right angles ; septa formed in transverse and in horizontal and vertical longitudinal planes giving rise to up to eight parallel rows of coccoid cells ( spores ), each of which becomes motile by a tuft of flagella . Gram‐stain‐positive. Not acid‐fast. Catalase‐positive. Aerobic and facultatively anaerobic . Nonfermentative, but acid is produced from certain carbohydrates. Growth reported only on complex media; minimum nutritional requirements unknown. Temperature optimum ∼37°C. Chondroitinase activity against chondroitin 4‐sulfate positive. No hyaluronidase or elastase activity. As determined for the type species, peptidoglycan contains meso ‐diaminopimelic acid ( meso ‐A 2 pm); madurose is present in whole‐cell hydrolysates; polar lipids include phosphatidylglycerol , diphosphatidylglycerol , and phosphatidylinositol ; major fatty acids are straight chain unsaturated C 16 : 0 , C 15 : 0 , and C 14 : 0 . Chemoorganotrophic. Parasitic on mammals , especially domestic herbivores . Pathology is usually limited to exudative dermatitis which may, however, be severe and life‐threatening; on rare occasions causes subcutaneous abscesses and lymph node granulomas. Also found in skin lesions and abscesses in chelonids. DNA G + C content ( mol %): 57–59 ( T m ). Type species : Dermatophilus congolensis Van Saceghem 1915, 357 emend. mut. char. Gordon 1964, 521.
