Investigation of a Multidrug-Resistant Raoultella Planticola (Formerly Klebsiella Planticola) Isolate from a Urine Culture: A Case Report
Christina Seitopoulou, Antonia Mourtzikou* and Maria Kimouli
Abstract
We report a case of Urinary Tract Infection (UTI) caused by a multidrug-resistant (MDR) Raoultella
planticola isolate recovered from a 65-year-old male with multiple comorbidities and recurrent UTIs.
Laboratory identification was performed using RAPID REMEL® systems and conventional culture on
blood Columbia agar, MacConkey agar and Sabouraud Dextrose agar. Antimicrobial susceptibility testing
followed the Kirby-Bauer disk diffusion method and interpretation according to EUCAST 2025 criteria.
The isolate exhibited resistance to multiple antimicrobial classes, necessitating referral for inpatient
intravenous therapy. We discuss the clinical significance, possible environmental exposure related to
gardening activities, and the importance of early recognition and appropriate antimicrobial stewardship
for emerging Raoultella infections.
