Abstract
Kurthia senegalensis strain JC8ET sp. nov. is the type strain of K. senegalensis sp. nov., a new species within the genus Kurthia. This strain, whose genome is described here, was isolated from the fecal flora of a healthy patient. K. senegalensis is an aerobic rod. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 2,975,103 bp long genome contains 2,889 protein-coding genes and 83 RNA genes, including between 4 and 6 rRNA genes.
Highlights
Kurthia senegalensis strain JC8ET (CSUR P138T = DSM 24641T) is the type strain of K. senegalensis sp. nov
JC8E exhibited a 96.8% nucleotide sequence similarity with K. massiliensis, the phylogenetically closest validated Kurthia species (Figure 1). This value was lower than the 97% 16S rRNA gene sequence threshold to delineate a new species without carrying out DNA-DNA hybridization recommended by the report of the ad hoc committee on reconciliation of approaches to bacterial systematics [2]
The JC8ET spectra were imported into the MALDI BioTyper software and analysed by standard pattern matching against the main spectra of 6,300 bacteria, including the spectra from K. gibsonii, K. sibirica, K. zopfii and K. massiliensis, in the BioTyper database
Summary
Sequencing whole prokaryote genomes is possible for more laboratories, and descriptions of sequencing protocols should be included in all species descriptions. Such activity would supplant the need for most other methods used during genome annotation, and new bioinformatics methods based on genome-togenome comparison have been proposed to replace the DDH approach [5]. Strain JC8ET together with the description of the complete genomic sequencing and annotation These characteristics support the circumscription of the species K. senegalensis. Classification and features A stool sample was collected from a healthy 16year-old male Senegalese volunteer patient living in Dielmo (a rural village in the Guinean-Sudanian zone in Senegal), who was included in a research protocol. The patient gave an informed and signed consent, and the agreement of the National Ethics Committee of Senegal and the local ethics
