Rare Lelliottia nimipressuralis from a wound infection case report using whole genome sequencing-based bacterial identification.

ABSTRACT

Identification of clinical bacterial isolates is an essential first step to provide guidelines for treatment of pathogenic bacterial infection. Infection occurred in a laceration along the medial aspect of left upper arm of a 71-year-old female. Conventional biochemical testing and MALDI-TOF MS identification failed to correctly identify a bacterial isolate. Using whole genome sequencing, the isolate was identified as Lelliottia nimipressuralis. WGS can overcome the limitations of conventional phenotypic and molecular identification methods and successfully identified a rare pathogen. This case is the first report of a human infection of L. nimipressuralis.
