# Urinary Tract Infection Due to Raoultella planticola in a Healthy Adult: A Report of a Rare Case

## TL;DR

A healthy woman experienced recurring urinary tract infections caused by the rare bacterium Raoultella planticola, highlighting its potential as an emerging uropathogen.

## Contribution

This report adds to the limited literature on Raoultella planticola as a rare cause of urinary tract infections in immunocompetent adults.

## Key findings

- Raoultella planticola was uniquely identified in urine cultures over a two-year period in an immunocompetent patient.
- The patient was successfully treated with trimethoprim-sulfamethoxazole.
- The case emphasizes the need for clinicians to consider R. planticola in recurrent UTI cases.

## Abstract

A 56-year-old immunocompetent woman presented with recurrent urinary tract infections (UTIs) over a two-year period, during which Raoultella planticola was uniquely identified in her urine culture. Recurrent UTIs are generally defined as two or more infections within six months, or three or more within one year, and often prompt further investigation to identify potential risk factors. This case report highlights the rarity of R. planticola as a causative agent of UTIs and underscores the importance of comprehensive microbiological evaluation in patients with recurrent infections. The patient was successfully treated with trimethoprim-sulfamethoxazole, and the antimicrobial susceptibility profile of the isolate is discussed. This case contributes to the limited body of literature on R. planticola-associated infections and emphasizes the need for clinicians to remain vigilant for this emerging uropathogen, particularly in cases of recurrent cystitis.
