Gemella massiliensis sp. nov., a new bacterium isolated from the human sputum.

Thanks to its ability to isolate previously uncultured bacterial species, culturomics has dynamized the study of the human microbiota. A new bacterial species, Gemella massiliensis Marseille-P3249T, was isolated from a sputum sample of a healthy French man. Strain Marseille-P3249T is a facultative anaerobe, catalase-negative, Gram positive, coccus, and unable to sporulate. The major fatty acids were C16:0 (34%), C18:1n9 (28%), C18:0 (15%) and C18:2n6 (13%). Its 16S rRNA sequence exhibits a 98.3% sequence similarity with Gemella bergeri strain 617-93T, its phylogenetically closest species with standing in nomenclature. Its digital DNA-DNA hybridization (dDDH) and OrthoANI values with G. bergeri of only 59.7 ± 5.6% and 94.8%, respectively. These values are lower than the thresholds for species delineation (> 70% and > 95%, respectively). This strain grows optimally at 37 °C and its genome is 1.80 Mbp long with a 30.5 mol% G + C content. Based on these results, we propose the creation of the new species Gemella massilienis sp. nov., strain Marseille-P3249T (= CSUR P3249 = DSMZ 103940).

Successful Fecal Microbiota Transplantation in a Patient Suffering From Irritable Bowel Syndrome and Recurrent Urinary Tract Infections.

BACKGROUND: Irritable bowel syndrome (IBS) is a chronic and debilitating functional gastrointestinal disorder affecting 9%-23% of the population across the world. The relative efficacy of fecal microbiota transplantation (FMT) on IBS symptoms was demonstrated in a double-blind, randomized study. METHODS: We describe the case of a 73-year-old woman suffering from IBS (abdominal pain, bloating, and abundant and disabling diarrhea, with 10-15 stools a day) and repetitive urinary tract infection (UTI; 5 episodes in 6 months, including 3 the last 2 months) for several years, generating an impaired quality of life. She received an FMT with 400 mL of fecal infusion from a healthy donor via a nasogastric tube after bowel lavage. Her digestive microbiota was analyzed using culturomic and metagenomic targeting 16S rRNA sequencing methods. RESULTS: Eight months after transplantation, we observed a significant reduction in frequency and improvement in stool consistency (3-4 molded stools a day against 10-15 before the transplant) and no recurrence of urinary infection (as previously reported). Using culturomics, we found 12 bacteria present in the fecal infusion and post-transplant stool; these were absent pretransplant. Three of them (Intestinimonas massiliensis, Oscillibacter massiliensis, and Provencibacter massiliensis) were previously discovered and cultivated in our laboratory using culturomics. Using metagenomics, we also observed 12 bacteria, different from those observed during culture, that could have been transferred to the patient by FMT. CONCLUSIONS: In this case report, IBS symptoms and UTI frequency decreased after FMT UTI. Further studies involving more patients would be relevant to confirm this work and develop bacteriotherapy.

Description of Janibacter massiliensis sp. nov., cultured from the vaginal discharge of a patient with bacterial vaginosis.

Strain Marseille-P4121T was isolated from a vaginal sample of a 45-year-old French woman with bacterial vaginosis. It is a Gram-positive, asporogenous, non-motile and aerobic bacterium. Strain Marseille-P4121T exhibits 98.2% 16S rRNA sequence similarity with Janibacter alkaliphilus strain SCSIO 10480T, a phylogenetically closely related species with standing in nomenclature. Its major fatty acids were identified as C18:1ω9 (34.4%), C16:0 (30.1%), and C18:0 (19%). The draft genome size of strain Marseille-P4121T is 2,452,608 bp long with a 72.5% G+C content and contains 2351 protein-coding genes and 49 RNA genes including 3 rRNA genes. We propose that strain Marseille-P4121T (= CECT 9671T = CSUR P4121T) is the type strain of the new species Janibacter massiliensis sp. nov.

Collinsella vaginalis sp. nov. strain Marseille-P2666T, a new member of the Collinsella genus isolated from the genital tract of a patient suffering from bacterial vaginosis.

A strictly anaerobic, Gram-stain-positive, non motile and non-spore-forming rod-shaped bacterium, strain Marseille-P2666T, was isolated using the culturomics approach from a vaginal sample of a French patient suffering from bacterial vaginosis. Cells were saccharolytic and were negative for catalase, oxidase, urease, nitrate reduction, indole production, hydrolysis of aesculin and gelatin. Strain Marseille-P2666T exhibited 97.04 % 16S rRNA sequence similarity to Collinsella tanakaei type strain YIT 12063T, the phylogenetically closest species with standing in nomenclature. The major fatty acids were C18:1ω9 (38 %), C16 : 0 (24 %) and C18 : 0 (19 %). The G+C content of the genome sequence of strain Marseille-P2666T is 64.6 mol%. On the basis of its phenotypic, phylogenetic and genomic features, strain Marseille-P2666T (=CSUR 2666T=DSM103342T) was classified as type strain of a novel species within the genus Collinsella for which the name Collinsella vaginalis sp. nov. is proposed.

Description and genomic characterization of Massiliimalia massiliensis gen. nov., sp. nov., and Massiliimalia timonensis gen. nov., sp. nov., two new members of the family Ruminococcaceae isolated from the human gut.

Using the culturomics approach, we isolated two strains, Marseille-P2963 and Marseille-P3753, from the intestinal microbiota of a 19-year-old healthy Saudi Arabian Bedouin male and from a 32-year-old healthy Senegalese male faecal transplant donor. Here, we studied their phenotypic, phylogenetic and genomic characteristics. Both strains were phylogenetically related, but different from Ruminococcus species. Bacterial cells were anaerobic, rod-shaped, non-spore-forming and not motile, with neither catalase nor oxidase activities. Their growth temperatures ranged from 28 to 45 °C, with an optimal growth at 37 °C. The genomes are 2,842,720 bp- and 2,707,061 bp-long respectively. The G + C contents are 47.18% and 46.90%, respectively. Based on these characteristics, we propose the creation of a new genus within the family Ruminococcaceae named Massiliimalia gen. nov., that contains the new species Massiliimalia massiliensis gen. nov., sp. nov., and Massiliimalia timonensis gen. nov., sp. nov. Strains Marseille-P2963T (= CSUR P2963 = DSM 106837) and Marseille-P3753T (= CSUR P3753 = CCUG 71632) are their type strains, respectively.

Dysgonomonas massiliensis sp. nov., a new species isolated from the human gut and its taxonogenomic description.

Culturomics has allowed the isolation of a significant number of new bacterial species from the human gut microbiota and proved to be a valuable complement to culture-independent techniques. Using this culture-based approach, a new bacterial species has been isolated from a stool sample of a 39-year-old healthy Pygmy male and described using the taxonogenomic strategy. Cells of strain Marseille-P4356T are Gram-stain negative cocci. The strain grows optimally at 37 °C and is catalase positive but oxidase negative. Its 16S rRNA gene sequence exhibited 92.96% sequence similarity with Dysgonomonas gadei strain JCM 16698T (NR_113134.1), currently its phylogenetically closest species that has been validly named. The genome of strain Marseille-P4356T is 3,472,011 bp long with 37.3 mol% G+C content. Phenotypic, biochemical, proteomic, genomic and phylogenetic analyses, clearly demonstrate that strain Marseille-P4356T (= CCUG 71356T = CSUR P4356T) represents a new species within the genus Dysgonomonas, for which we propose the name Dysgonomonas massiliensis sp. nov.

Atypical Cowpox Virus Infection in Smallpox-Vaccinated Patient, France.

We report a case of atypical cowpox virus infection in France in 2016. The patient sought care for thoracic lesions after injury from the sharp end of a metallic guardrail previously stored in the ground. We isolated a cowpox virus from the lesions and sequenced its whole genome. The patient reported that he had been previously vaccinated against smallpox. We describe an alternative route of cowpox virus infection and raise questions about the immunological status of smallpox-vaccinated patients for circulating orthopoxviruses.

Draft genome and description of Cohnella massiliensis sp. nov., a new bacterial species isolated from the blood culture of a hemodialysis patient.

Strain 6021052837T was isolated from the blood culture of a hemodialysis patient on Chocolat PolyViteX medium at 37 °C after 2 days of incubation. Colonies could not be identified by our systematic MALDI-TOF Mass Spectrometry screening. The16S rRNA gene sequencing showed that the strain had 96% sequence identity with Cohnella formosensis (Genbank accession number JN806384), the phylogenetic closely related type strain of a species with standing in nomenclature, which putatively classifies it as a new species. The colonies cultivated on Columbia agar with 5% sheep blood medium at 37 °C after 24 h of incubation, are white pigmented, their size varied from 1.5 to 2 mm in diameter. Strain 6021052837T is an aerobic, Gram-negative, motile, spore forming rod, which cannot grow microaerophilically or under anaerobic conditions. The major fatty acids are branched saturated fatty acids: 14-methyl-pentadecanoic acid (34%) and 12-methyl-tetradecanoic acid (31%). The 6.328 Mb long genome, composed of 25 contigs, has a G+C content of 57.24%. Out of the 5710 predicted genes, 5646 were protein-coding genes and 64 were RNAs. A total of 3239 genes (57.37%) were assigned as putative function (by COGs) and 288 genes were identified as ORFans (5.1%). Average genomic identity of orthologous gene sequences (AGIOS) of strain 6021052837T against genomes of the type strains of related species ranged between 58.26 and 79.63%, respectively. According to our taxonogenomics results, we propose the creation of Cohnella massiliensis sp. nov. that contains the type strain 6021052837T (= CSUR P2659, =DSM103435).
