Summary
Pseudomonas fluorescens infection in an immunocompromised patient was successfully treated with ceftazidime after initial therapy failed. This case highlights challenges in diagnosing and treating infections caused by less virulent Pseudomonas species.
Area of Science:
- Clinical microbiology
- Infectious diseases
- Medical case reports
Background:
- Pseudomonas fluorescens, a member of the Pseudomonadaceae family, is generally considered less virulent.
- Infections caused by P. fluorescens are uncommon, particularly in non-nosocomial settings.
- Immunocompromised individuals are at higher risk for opportunistic infections.
Observation:
- A case of P. fluorescens bacteremia in an elderly, immunocompromised patient presenting with fever.
- Initial empirical antibiotic therapy was unsuccessful.
- The patient's infection was successfully treated with ceftazidime.
Findings:
- Successful treatment of P. fluorescens infection with ceftazidime.
- Challenges associated with the isolation and susceptibility testing of P. fluorescens.
- Discussion of the epidemiology of P. fluorescens infections.
Implications:
- Ceftazidime can be an effective treatment option for P. fluorescens infections.
- Highlights the importance of accurate pathogen identification and susceptibility testing, even for less common organisms.
- Underscores the need for vigilance in diagnosing and managing infections in immunocompromised patients.
