Abstract
Clostridium dakarense strain FF1T, is the type strain of Clostridium dakarense sp. nov., a new species within the genus Clostridium. This strain, whose genome is described here, was isolated from the fecal flora of a 4-month-old Senegalese child suffering from gastroenteritis. C. dakarense sp. nov. strain FF1T is an obligate anaerobic Gram-positive bacillus. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 3,735,762 bp long genome (1 chromosome but no plasmid) exhibits a G+C content of 27.98% and contains 3,843 protein-coding and 73 RNA genes, including 8 rRNA genes.
Highlights
Clostridium dakarense strain FF1T (= CSUR P243 = DSM 27086), is the type strain of Clostridium dakarense sp. nov. This bacterium is a Grampositive, anaerobic, spore-forming, indole negative bacillus that was isolated from the stool of a 4-month-old Senegalese child suffering from gastroenteritis as part of a “culturomics” study aiming at cultivating individually all species within human feces
The organism was selected for sequencing on the basis of its phylogenetic position and 16S rRNA similarity to other members of the genus Clostridium, and is part of a “culturomics” study of the human digestive flora aiming at isolating all bacterial species within human feces
On the basis of phenotypic, phylogenetic and genomic analyses, we formally propose the creation of Clostridium dakarense sp. nov. which contains strain FF1T
Summary
We proposed to use a polyphasic approach [4] to describe new bacterial taxa, including genome sequence, MALDI-TOF spectrum and main phenotypic characteristics [5,6,7,8,9,10,11]. Members of the genus Clostridium are mostly environmental bacteria or associated with the commensal digestive flora of mammals, but several are major human pathogens, including C. botulinum, C. difficile, C. tetani and C. perfringens [14,15]. Strain FF1T (= CSUR P243 = DSM 27086) together with the description of the complete genomic sequencing and annotation. These characteristics support the circumscription of the species C. dakarense sp. These characteristics support the circumscription of the species C. dakarense sp. nov
