Metagenomics revolutionized the understanding of the relations among the human microbiome, health and diseases, but generated a countless number of sequences that have not been assigned to a known microorganism1. The pure culture of prokaryotes, neglected in recent decades, remains essential to elucidating the role of these organisms2. We recently(More)
Various methods are currently used to define species and are based on the phylogenetic marker 16S ribosomal RNA gene sequence, DNA-DNA hybridization and DNA GC content. However, these are restricted genetic tools and showed significant limitations. In this work, we describe an alternative method to build taxonomy by analyzing the pan-genome composition of(More)
Microvirga massiliensis sp. nov. strain JC119(T) is a bacteria isolated in Marseille from a stool sample collected in Senegal. The 16S rRNA (JF824802) of M. massiliensis JC119(T) revealed 95% sequence identity with Microvirga lotononidis WSM3557(T) (HM362432). This bacterium is aerobic, gram negative, catalase positive, and oxidase negative. The draft(More)
BACKGROUND Phlebotomine sand flies are known to transmit Leishmania parasites, bacteria and viruses that affect humans and animals in many countries worldwide. Precise sand fly identification is essential to prevent phlebotomine-borne diseases. Over the past two decades, progress in matrix-assisted laser desorption/ionization time-of-flight mass(More)
Alterations in gut microbiota composition under antibiotic pressure have been widely studied, revealing a restricted diversity of gut flora, including colonization by organisms such as Enterococci, while their impact on bacterial load is variable. High-level colonization by Akkermansia muciniphila, ranging from 39% to 84% of the total bacterial population,(More)
Nosocomiicoccus massiliensis strain NP2(T) sp. nov. is the type strain of a new species within the genus Nosocomiicoccus. This strain, whose genome is described here, was isolated from the fecal flora of an AIDS-infected patient living in Marseille, France. N. massiliensis is a Gram-positive aerobic coccus. Here we describe the features of this organism,(More)
Paenibacillus ihumii sp. nov. strain AT5 (= CSUR 1981 = DSM 100664) is the type strain of P. ihumii. This bacterium was isolated from a stool sample from a morbidly obese French patient using the culturomics approach. The genome of this Gram-negative, facultative anaerobic, motile and spore-forming bacillus is 5 924 686 bp long. Genomic analysis identified(More)
Holdemania massiliensis strain AP2(T) sp. nov. is the type strain of H. massiliensis sp. nov., a new species within the genus Holdemania. This strain, whose genome is described here, was isolated from the fecal flora of a 21-year-old French Caucasian female suffering from severe restrictive anorexia nervosa. H. massiliensis is a Gram-positive, anaerobic(More)
Corynebacterium jeddahense sp. nov., strain JCB(T), is the type strain of Corynebacterium jeddahense sp. nov., a new species within the genus Corynebacterium. This strain, whose genome is described here, was isolated from fecal flora of a 24-year-old Saudi male suffering from morbid obesity. Corynebacterium jeddahense is a Gram-positive, facultative(More)
Strain FF3(T) was isolated from the skin-flora of a 39-year-old healthy Senegalese man. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry did not allow any identification. This strain exhibited a 16S rRNA sequence similarity of 96.8% with Bacillus massiliensis, the phylogenetically closest species with standing nomenclature. Using(More)
