Abstract:
We report a case of nephrostomy-associated urinary tract infection caused by Elizabethkingia meningoseptica that occurred in a patient with retroperitoneal fibrosis. Though conventional identification methods failed to detect the causative organism, it was identified on the basis of the complete sequencing of 16S rRNA. Four weeks of levofloxacin and minocycline administration successfully eradicated the infection. E. meningoseptica rarely causes urinary tract infections, and we believe that this is the first such case in which the isolate was genetically confirmed. The accurate identification of the organism is necessary for the provision of appropriate treatment and to obtain a better understanding of its epidemiology and pathogenicity.
Insights
A rare Elizabethkingia meningoseptica urinary tract infection (UTI) occurred in a patient with retroperitoneal fibrosis. Genetic sequencing confirmed the organism, and treatment with levofloxacin and minocycline was successful.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Genomics
Background:
- Nephrostomy-associated urinary tract infections (UTIs) are a concern in patients with urinary tract abnormalities.
- Retroperitoneal fibrosis can predispose patients to complex infections.
- Elizabethkingia meningoseptica is an emerging pathogen, rarely implicated in UTIs.
Observation:
- A patient with retroperitoneal fibrosis developed a nephrostomy-associated UTI.
- Conventional microbiological methods failed to identify the causative agent.
- Complete sequencing of the 16S rRNA gene was crucial for accurate organism identification.
Findings:
- The causative organism was identified as Elizabethkingia meningoseptica.
- The infection was successfully treated with a four-week course of levofloxacin and minocycline.
- This represents the first genetically confirmed case of nephrostomy-associated UTI caused by E. meningoseptica.
Implications:
- Accurate identification of E. meningoseptica is essential for effective treatment of UTIs.
- This case highlights the importance of advanced molecular techniques in diagnosing challenging infections.
- Further research into the epidemiology and pathogenicity of E. meningoseptica in urinary tract infections is warranted.
