Abstract
A Gram-stain-negative, short rod-shaped strain, MDT2-1-1T, was isolated from cryoconite samples collected from the Midui glacier in Tibet, China. It grew aerobically from 7 to 40 °C, within a pH range of 6.0-10.0, and in NaCl concentration of 0 to 1.0% (w/v). The pairwise 16S rRNA gene sequence similarity, average nucleotide identity and digital DNA-DNA hybridization values between strains MDT2-1-1T and Sabulicella rubraurantiaca SYSU D01096T were 99.4%, 89.7% and 38.9%, respectively. Considering the results from phylogeny, phenotypic and genotypic data, strain MDT2-1-1T (=CGMCC 1.11170T = NBRC 110485T) was suggested to represent a novel species of the genus Sabulicella, for which the name Sabulicella glaciei sp. nov. is proposed. Furthermore, based on the phylogenomic analysis, it is recommended that Roseomonas rubea, Roseomonas ponticola and Roseomonas oleicola be reclassified as Neoroseomonas rubea comb. nov., Falsiroseomonas ponticola comb. nov. and Falsiroseomonas oleicola comb. nov., respectively. Considering the illegitimate status of the genera names Pararoseomonas and Pseudoroseomonas, the species within the genera Pararoseomonas and Pseudoroseomonas should be transferred to Muricoccus and Teichococcus, respectively. Therefore, we proposed the following new combinations: Muricoccus aeriglobus comb. nov., Muricoccus aerilatus comb. nov., Muricoccus harenae comb. nov., Muricoccus nepalensis comb. nov., Muricoccus pecuniae comb. nov., Muricoccus radiodurans comb. nov., Muricoccus vinaceus comb. nov., Teichococcus aerofrigidensis comb. nov., Teichococcus aerophilus comb. nov., Teichococcus aestuarii comb. nov., Teichococcus cervicalis comb. nov., Teichococcus coralli comb. nov., Teichococcus deserti comb. nov., Teichococcus globiformis comb. nov., Teichococcus hibiscisoli comb. nov., Teichococcus musae comb. nov., Teichococcus oryzae comb. nov., Teichococcus rhizosphaerae comb. nov., Teichococcus ruber comb. nov., Teichococcus suffuscus comb. nov., Teichococcus vastitatis comb. nov., and Teichococcus wenyumeiae comb. nov.

Abstract
Roseomonas mucosa (R. mucosa) is a pink-pigmented, aerobic, nonfermentative, slow-growing Gram-negative coccus typically isolated from the natural environment, human skin, and hospital environment. This pathogen, in most circumstances, leads to infections in immunocompromised hosts, but it may sometimes invade immunocompetent individuals. Bacteraemia is the most common form of infection caused by R. mucosa. In contrast, only two case reports have described R. mucosa-related epidural abscess formation and infective spondylitis. In this case report, we shared the history and treatment experience of a 76-year-old female who was diagnosed with infective spondylitis and epidural abscess caused by R. mucosa. She received a local transdermal injection into the lower back to relieve her back pain two months before symptom onset, which was considered to be associated with this infection episode. After admission to the hospital, neurosurgeons performed emergent decompression and debridement. She was treated with intravenous ceftriaxone for four weeks, followed by oral ciprofloxacin for another eight weeks. The patient recovered well without any sequelae and had no relapse of infection at least six months after the end of treatment. In addition to the case report, we reviewed the literature for reported cases caused by R. mucosa. Our experience suggests that clinicians should include R. mucosa as one of the possible healthcare-associated pathogens among individuals who have undergone transdermal procedures. We believe that this article will help clinicians better recognize R. mucosa infection.

Abstract
A pink, ovoid-shaped, Gram-stain-negative, strictly aerobic and motile bacterial strain, designated ROY-5-3T, was isolated from an oil production mixture from Yumen Oilfield in PR China. The strain grew at 4-42 °C (optimum, 30 °C), at pH 5-10 (optimum, 7) and with 0-5 % (w/v) NaCl (optimum, 0%). The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that ROY-5-3T belongs to the genus Roseomonas and shared the highest pairwise similarities with Roseomonas frigidaquae CW67T (98.1%), Roseomonas selenitidurans BU-1T (97.8%), Roseomonas tokyonensis K-20T (97.7%) and Roseomonas stagni HS-69T (97.3%). The average nucleotide identity and digital DNA-DNA hybridization values between ROY-5-3T and other related type strains of Roseomonas species were less than 84.08 and 28.60 %, respectively, both below the species delineation threshold. Pan-genomic analysis showed that the novel isolate ROY-5-3T shared 3265 core gene families with the four closely related type strains in Roseomonas, and the number of strain-specific gene families was 513. The major fatty acids were identified as summed feature 8 (C18 : 1 ω6c/C18 : 1 ω7c), summed feature 3 (C16 : 1 ω6c/C16 : 1 ω7c) and C16 : 0. Strain ROY-5-3T contained Q-10 as the main ubiquinone and the genomic DNA G+C content was 69.8 mol%. The major polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and phosphatidylglycerol. Based on the phylogenetic, morphological, physiological, chemotaxonomic and genome analyses, strain ROY-5-3T represents a novel species of the genus Roseomonas for which the name Roseomonas oleicola sp. nov. is proposed. The type strain is ROY-5-3T (=CGMCC 1.13459T =KCTC 82484T).

Front Microbiol 2021; 12:677842. [PMID: 34484138 PMCID: PMC8414978 DOI: 10.3389/fmicb.2021.677842] [Citation(s) in RCA: 176] [Impact Index Per Article: 58.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Accepted: 06/08/2021] [Indexed: 01/10/2023] Open
Abstract
The genus Roseomonas is a significant group of bacteria which is invariably of great clinical and ecological importance. Previous studies have shown that the genus Roseomonas is polyphyletic in nature. Our present study focused on generating a lucid understanding of the phylogenetic framework for the re-evaluation and reclassification of the genus Roseomonas. Phylogenetic studies based on the 16S rRNA gene and 92 concatenated genes suggested that the genus is heterogeneous, forming seven major groups. Existing Roseomonas species were subjected to an array of genomic, phenotypic, and chemotaxonomic analyses in order to resolve the heterogeneity. Genomic similarity indices (dDDH and ANI) indicated that the members were well-defined at the species level. The Percentage of Conserved Proteins (POCP) and the average Amino Acid Identity (AAI) values between the groups of the genus Roseomonas and other interspersing members of the family Acetobacteraceae were below 65 and 70%, respectively. The pan-genome evaluation depicted that the pan-genome was an open type and the members shared 958 core genes. This claim of reclassification was equally supported by the phenotypic and chemotaxonomic differences between the groups. Thus, in this study, we propose to re-evaluate and reclassify the genus Roseomonas and propose six novel genera as Pararoseomonas gen. nov., Falsiroseomonas gen. nov., Paeniroseomonas gen. nov., Plastoroseomonas gen. nov., Neoroseomonas gen. nov., and Pseudoroseomonas gen. nov.

Abstract
A Gram-stain-negative, aerobic, non-motile, pink-pigmented, coccus bacterium, designated CPCC 101081T, was isolated from a gravel soil sample collected from Badain Jara desert, PR China. Growth of the isolate occurred at 10-37 °C and pH 5.0-8.0, with optimal growth at 28-32 °C and pH 7.0, respectively. The major cellular fatty acids were summed feature 8 (C18:1ω7c/C 18:1ω6c), summed feature 3 (C 16:1ω6c/C16:1ω7c) and C18:12-OH. Q-10 was detected as the main respiratory quinone. Diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an unidentified phospholipid, an amino-containing lipid and an unidentified glycophospholipid were examined in the polar lipids extraction. The 16S rRNA gene sequence comparison of strain CPCC 101081T with the available sequences in the GenBank database showed that the isolate was closely related to members of the genus Rosenomonas, with the highest similarity to Roseomonas rosea DSM 14916T (97.4 %). In the phylogenetic trees based on 16S rRNA gene sequences and the core genomes, strain CPCC 101081T was included within the clade of the genus Roseomonas, representing a species level, with the closest neighbor of R. rosea DSM 14916T . The genomic DNA G+C content was 68.7 mol%. The average nucleotide identity and the digital DNA-DNA hybridization values between strain CPCC 101081T and the related type strains of the genus Roseomonas were all far lower than the cut-off values for definition species. On the basis of above phenotypic and genotypic characteristics, strain CPCC 101081T is proposed to represent a novel species of the genus Roseomonas with the name Roseomonas harenae sp. nov. strain CPCC 101081T (=KCTC 62852T=NBRC 113512T) is the type strain of the species.
