Culturomics studies the microbial variety of the human microbiome by combining diversified culture conditions, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rRNA gene identification. This study identifies three putative new bacterial species: sp. nov. strain Marseille-P5647, sp. nov. strain Marseille-P5644 and sp. nov. strain Marseille-P5995, which we describe according to the concept of taxonogenomics.

Review
Members of the Actinomyces genus and Actinomyces-like organisms (ALOs; namely Actinotignum, Arcanobacterium, Schaalia and Varibaculum) are Gram-positive, non-spore-forming rods that are commensal members of the human oral cavity, gastrointestinal tract, female genital tract and skin microbiota. Cervicofacial actinomycosis or "lumpy jaw syndrome" - the chronic, suppurative granulomatous disease caused by Actinomyces spp. And ALOs - is characterized by an initially slow and unspecific disease-presentation, which often mimics other pathologies, followed by the formation of painful abscesses and severe tissue destruction. Actinomycosis has been described as a rare disease, however, reliable epidemiological data are lacking. In addition, there is increasing awareness regarding the role of Actinomyces spp. in the development of osteoradionecrosis and medication-related osteonecrosis of the jaw. The aim of this narrative review is to succinctly summarize the current advances regarding the microbiological, clinical, diagnostic and therapeutic aspects of cervicofacial actinomycosis, in addition to the roles of Actinomyces species and ALOs as members of the oral microbiota and in dental biofilm, in other dental infections (caries, root canal infection, periapical infection, periodontitis) and osteonecrosis of the jaw, in the context of recent taxonomic changes affecting the genus. Our paper aims to be a blueprint for dentists, other physicians, microbiologists and researchers regarding the multifaceted field of cervicofacial actinomycosis.

Systematic and Applied Microbiology Dec 2016During the years 1994-2011 five strictly anaerobic, Gram-stain-positive, diphtheroid bacteria (strains CCUG 31793, CCUG 44221, CCUG 61255, CCUG 45114, and CCUG 44993)...
During the years 1994-2011 five strictly anaerobic, Gram-stain-positive, diphtheroid bacteria (strains CCUG 31793, CCUG 44221, CCUG 61255, CCUG 45114, and CCUG 44993) were isolated from different clinical samples in Sweden and the United Kingdom. Comparative analysis of 16S rRNA gene sequences showed that the five strains shared 99-100% 16S rRNA gene sequence similarity among each other and 98.3-98.6% sequence similarity to Varibaculum cambriense DSM 15806. Genomic fingerprint patterns generated with ERIC-, BOX-, and RAPD-PCR, and whole genome sequence (WGS) based comparison by in silico DNA-DNA hybridization (isDDH), average nucleotide identity (ANI) analysis and six housekeeping gene (atpA, rpoB, pgi, metG, gltA and gyrA) based multilocus sequence analysis (MLSA) showed that the strains could be differentiated from V. cambriense DSM 15806 and formed three genomic groups, which could only be differentiated at the species border level. Based on physiological characterizations the five strains could not be clearly distinguished among each other. Based on those data a new Varibaculum species, Varibaculum anthropi (type strain CCUG 31793=JCM 19104) is proposed including three genetically distinct genomovars (gv 1: CCUG 31793, CCUG 44221, CCUG 61255; gv 2: CCUG 45114, and gv 3: CCUG 44993).

Fifteen strains of an anaerobic, catalase-negative, gram-positive diphtheroid-shaped bacterium recovered from human sources were characterized by phenotypic and molecular chemical and molecular genetic methods. The unidentified bacterium showed some resemblance to Actinomyces species and related taxa, but biochemical testing, polyacrylamide gel electrophoresis analysis of whole-cell proteins, and amplified 16S ribosomal DNA restriction analysis indicated the strains were distinct from all currently named Actinomyces species and related taxa. Comparative 16S rRNA gene sequencing studies showed that the bacterium represents a hitherto-unknown phylogenetic line that is related to but distinct from Actinomyces, Actinobaculum, Arcanobacterium, and Mobiluncus: We propose, on the basis of phenotypic and phylogenetic evidence, that the unknown bacterium from human clinical specimens should be classified as a new genus and species, Varibaculum cambriensis gen. nov., sp. nov. The type strain of Varibaculum cambriensis sp. nov. is CCUG 44998(T) = CIP 107344(T).
