description of clostridium cagae sp nov clostridium rectalis sp nov and hathewaya massiliensis sp nov new anaerobic bacteria isolated from human stool samples
new microbes and new infections, 2020Co-Authors: Mamadou Lamine Tall, Cheikh Ibrahima Lo, P E Fournier, Souhaibou Ndongo, Anthony Levasseur, Florence Fenollar, Didier Raoult, Kuete E Yimagou, T P T PhamAbstract:Abstract Using culturomics methods, three strains were isolated, identified and characterized following the taxonogenomics concept. Clostridium cagae strain Marseille-P4344T (=CSURP4344), Clostridium rectalis strain Marseille-P4200T (=CSURP4200) and Hathewaya massiliensis strain Marseille-P3545T (=CSURP3545) were isolated from human stool samples. The phylogenetic reconstruction, phenotypic criteria and genomic analyses were carried out and demonstrated that these three bacteria are different from previously known bacterial species with standing in nomenclature and were classified as new members of the Clostridiaceae family.

taxono genomics and description of haloimpatiens massiliensis sp nov a new bacterium isolated from the gut of a healthy infant
new microbes and new infections, 2020Co-Authors: Hussein Anani, Anthony Fontanini, Tidjani M Alou, Didier Raoult, Jean Christophe Lagier, Pierre-edouard FournierAbstract:Abstract A polyphasic taxono-genomic strategy was used to describe a new bacterium, strain Marseille-P1935; isolated from the gut of a healthy infant. 16S rRNA sequencing showed that the isolate belongs to the genus Haloimpatiens in the family Clostridiaceae. Phenotypic analysis and whole-genome sequence analyses confirm the status of the new species. We propose the creation of the new species Haloimpatiens massiliensis strain Marseille-P1935T (= CSURP1935T; = DSM100591T).

Massilioclostridium coli gen. nov., sp. nov., a new member of the Clostridiaceae family isolated from the left colon of a 27-year-old woman
New Microbes and New Infections, 2017Co-Authors: M. Mailhe, Pierre-edouard Fournier, Didier Raoult, D. Ricaboni, V. Vitton, A. Benezech, C. Michelle, N. Armstrong, F. Bittar, J.-c. LagierAbstract:Massilioclostridium coli gen. nov., sp. nov., a new member of the Clostridiaceae family isolated from the left colon of a 27-year-old woman Abstract Massilioclostridium coli strain Marseille-P2976 T (= CSUR P2976 = DSM 103344) is a new bacterial genus isolated from the left colon of a patient who underwent colonoscopy for colorectal cancer screening. Massilioclostridium coli is a Gram-negative bacillus, strict anaerobic, nonsporogenous and nonmotile organism. We describe here the strain Marseille-P2976 T and provide its complete annotated genome sequence according to taxonogenomics concepts. Its genome is 2 985 330 bp long and contains 2562 predicted genes and 75 RNA genes.

Genome sequence and description of Desnuesiella massiliensis gen. nov., sp. nov. a new member of family Clostridiaceae
New microbes and new infections, 2016Co-Authors: Linda Hadjadj, Maryam Tidjani Alou, Didier Raoult, Jean Christophe Lagier, Sokhna, Jean-marc RolainAbstract:Desnuesiella massiliensis, strain MT10T gen. nov., sp. nov. is a newly proposed genus within the family Clostridiaceae, isolated from the digestive microbiota of a child suffering from kwashiorkor. Desnuesiella massiliensis is a facultatively anaerobic, Gram-positive rod. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 5 503 196-bp long genome (one chromosome but no plasmid) contains 5227 protein-coding and 81 RNA genes, including 14 rRNA genes.

Sporosalibacterium faouarense gen. nov., sp. nov., a moderately halophilic bacterium isolated from oil-contaminated soil
International Journal of Systematic and Evolutionary Microbiology, 2011Co-Authors: Raja Rezgui, Said Ben Hamed, Marie Laure Fardeau, Jean Luc Cayol, Abderrazak Maaroufi, Marc LabatAbstract:A novel strictly anaerobic, moderately halophilic and mesophilic bacterium, designated strain SOL3f37(T), was isolated from a hydrocarbon-polluted soil surrounding a deep petroleum environment located in south Tunisia. Cells of strain SOL3f37(T) stained Gram-positive and were motile, straight and spore-forming. Strain SOL3f37(T) had a typical Gram-positive-type cell-wall structure, unlike the thick, multilayered cell wall of its closest relative Clostridiisalibacter paucivorans. The major fatty acids were iso-C-15:0 (41 %), iso-C-14:0 3-OH and/or iso-C-15:0 dimethyl acetal (21.6%), iso-C-13:0 (4.4%), anteiso-C-15:0 (3.9%) and iso-C-15:1 (2.8%). Strain SOL3f37(T) grew between 20 and 48 degrees C (optimum 40 degrees C) and at pH 6.2-8.1 (optimum pH 6.9). Strain SOL3f37(T) required at least 0.5 g NaCl l(-1) and grew in the presence of NaCI concentrations up to 150 g (optimum 40 g l(-1)). Yeast extract (2 g l(-1)) was required for degradation of pyruvate, fumarate, fructose, glucose and mannitol. Also, strain SOL3f37(T) grew heterotrophically on yeast extract, peptone and bio-Trypticase, but was unable to grow on Casamino acids. Sulfate, thiosulfate, sulfite, elemental sulfur, fumarate, nitrate and nitrite were not reduced. The DNA G+C content was 30.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SOL3f37(T) was a member of the family Clostridiaceae in the order Clostridiales; strain SOL3f37(T) was related to members of various genera of the family Clostridiaceae. It exhibited highest 16S rRNA gene sequence similarity (93.4%) with Clostridiisalibacter paucivorans 37HS60(T), 91.8% with Thermohalobacter berrensis CTT3(T) and 91.7% with Caloranaerobacter azorensis MV1087(T). On the basis of genotypic, phenotypic and phylogenetic data, it is suggested that strain SOL3f37(T) represents a novel species in a new genus. The name Sporosalibacterium faouarense gen. nov., sp. nov. is proposed, with SOL3f37(T) (=DSM 21485(T) =JCM 15487(T)) as the type strain of Sporosalibacterium faouarense.
