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

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.
