Genomic analysis reveals multidrug resistance and diagnostic misidentification in a urinary isolate, highlighting the value of whole-genome sequencing.
Raoultella ornithinolytica was isolated from a patient’s urine. This strain was misidentified as Klebsiella oxytoca by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF), but whole-genome sequencing identified it as Raoultella ornithinolytica and detected Raoultella -specific hdc gene. This isolate showed beta-lactams, fluoroquinolones, and tetracycline resistance. Here, we report the genome and antimicrobial susceptibility of this strain.
