title: Helcobacillus massiliensis gen. nov., sp. nov., a novel representative of the family Dermabacteraceae isolated from a patient with a cutaneous discharge.
abstract: Gram-positive, non-spore-forming rods (strain 6401990T), isolated from a human cutaneous discharge were subjected to a polyphasic taxonomy study. The only respiratory quinone was MK-7 and the major fatty acids were anteiso-C15:0 (34.3%), anteiso-C17:0 (18.7%) and iso-C16:0 (18.6%). Mycolic acids were not present. Polar lipids present were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and unidentified glycolipids. The isomer of diaminopimelic acid identified was meso-diaminopimelic acid, and the analysis of whole-cell sugars showed the presence of high amounts of galactose, ribose and some glucose. The G+C content of strain 6401990T was 68.6%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed 95.1% similarity with Dermabacter hominis. On the basis of phenotypic data and phylogenetic inference, it is proposed that this strain represents a novel species in a new genus of the family Dermabacteraceae, for which the name Helcobacillus massiliensis gen. nov., sp. nov. is proposed. The type strain is 6401990T (CSUR P17T=CIP 109418T=CCUG 53859T).
