Abstract

Enterobacter bugandensis is a recently described species that has been largely associated with nosocomial infections. We report the genome of a non-clinical E. bugandensis strain, which was integrated with publicly available genomes to study the pangenome and general population structure of E. bugandensis. Core- and whole-genome multilocus sequence typing allowed the detection of five E. bugandensis phylogroups (PG-A to E), which contain important antimicrobial resistance and virulence determinants. We uncovered several extended-spectrum β-lactamases, including bla CTX-M-55 and bla NDM-5, present in an IncX replicon type plasmid, described here for the first time in E. bugandensis. Genetic context analysis of bla NDM-5 revealed the resemblance of this plasmid with other IncX plasmids from other bacteria from the same country. Three distinctive siderophore producing operons were found in E. bugandensis: enterobactin (ent), aerobactin (iuc/iut), and salmochelin (iro). Our findings provide novel insights on the lifestyle, physiology, antimicrobial, and virulence profiles of E. bugandensis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
