Abstract

Background

Staphylococcus xylosus is coagulase-negative staphylococci (CNS), found occasionally on the skin of humans but recurrently on other mammals. Recent reports suggest that this commensal bacterium may cause diseases in humans and other animals. In this study, we present the first report of whole genome sequencing of S. xylosus strain DMB3-Bh1, which was isolated from the stool of a mouse.

Results

The draft genome of S. xylosus strain DMB3-Bh1 consisted of 2,81,0255 bp with G+C content of 32.7 mol%, 2623 predicted coding sequences (CDSs) and 58 RNAs. The final assembly contained 12 contigs of total size 2,81,0255 bp with N50 contig length of 4,37,962 bp and the largest contig assembled measured 7,61,338 bp. Further, an interspecies comparative genomic analysis through rapid annotation using subsystem technology server was achieved with Staphylococcus aureus RF122 that revealed 36 genes having similarity with S. xylosus DMB3-Bh1. 35 genes encoded for virulence, disease and defense and 1 gene encoded for phages, prophages and transposable elements.

Conclusions

These results suggest co linearity in genes between S. xylosus DMB3-Bh1 and S. aureus RF122 that contribute to pathogenicity and might be the result of horizontal gene transfer. The study indicates that S. xylosus DMB3-Bh1 may be a potential emerging pathogen for rodents.

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
