Raoultella ornithinolytica Urinary Tract Infection in a Patient With Triple-Negative Breast Cancer.

Due to the challenges associated with accurately identifying Raoultella ornithinolytica as the causative agent in urinary tract infections (UTIs), coupled with limited guidance on treatment protocols, reports of similar cases still need to be made publicly available because of their increasing emergence. In this article, we present the first documented case of a UTI caused by Raoultella ornithinolytica in a patient with triple-negative breast cancer undergoing neoadjuvant chemotherapy. This case report highlights Raoultella ornithinolytica as an uncommon yet significant pathogen, particularly in immunocompromised patients. Given the bacterium's antibiotic resistance patterns, it emphasizes the importance of prompt, accurate identification methods and tailored treatment strategies, especially in vulnerable populations undergoing chemotherapy.
