Abstract
Dielma fastidiosa strain JC13T gen. nov., sp. nov. is the type strain of D. fastidiosa gen. nov., sp. nov., the type species of a new genus within the family Erysipelotrichaceae. This strain, whose draft genome is described here, was isolated from the fecal flora of a healthy 16-year-old male Senegalese volunteer. D. fastidiosa is a Gram-negative anaerobic rod. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 3,574,031 bp long genome comprises a 3,556,241-bp chromosome and a 17,790-bp plasmid. The chromosome contains 3,441 protein-coding and 50 RNA genes, including 3 rRNA genes, whereas the plasmid contains 17 protein-coding genes.
Highlights
Dielma fastidiosa strain JC13T (CSUR P149 / DSM 26099) is the type strain of D. fastidiosa gen. nov., sp. nov., the type species of Dielma gen. nov
The conventional genotypic methods used in bacterial taxonomy include 16S rRNA gene-based phylogeny and nucleotide similarity [3,4], determination of the G + C content and DNA–DNA hybridization (DDH) [5,6]
DDH and 16S rRNA gene similarity cutoffs are considered as gold standards in bacterial taxonomy, they have some limitations as they do not apply well to all species or genera [3]
Summary
Dielma fastidiosa strain JC13T (CSUR P149 / DSM 26099) is the type strain of D. fastidiosa gen. nov., sp. nov., the type species of Dielma gen. nov. The introduction of high-throughput genome sequencing and proteomic analyses [7] provided a source of comprehensive information about studied bacterial isolates. Such data may be included among the criteria used for taxonomic identification. Strain JC13T (CSUR P149 / DSM 26099) together with the description of the complete genome sequencing and annotation. These characteristics support the circumscription of the genus Dielma and its type species, D. fastidiosa within the family Erysipelotrichaceae. These bacteria were isolated from patients with oral infection and acute appendicitis [36,37,38,39,40]
