Abstract:
Pseudomonas putida is an uncommon cause of bacteremia, that usually seeds from multiple sources including soft tissues. Immunocompromised states predispose patients to fulminant infections, and sometimes death. Broad-spectrum antibiotics, such as fourth-generation cephalosporins, are usually indicated for treatment. Herein, we present a 71-year-old gentleman with fever and left leg swelling, found to have P. putida bacteremia. Intravenous (IV) ceftazidime was initiated, yielding clearance of blood cultures and clinical improvement.
Insights
Pseudomonas putida bacteremia is rare but serious, often linked to soft tissue infections. Prompt treatment with broad-spectrum antibiotics like ceftazidime can lead to recovery.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Clinical Medicine
Background:
- Pseudomonas putida is an infrequent cause of bloodstream infections (bacteremia).
- Immunocompromised individuals are particularly susceptible to severe Pseudomonas putida infections.
- Soft tissue infections are a common origin for Pseudomonas putida bacteremia.
Observation:
- A 71-year-old male presented with fever and swelling in his left leg.
- Blood cultures confirmed the presence of Pseudomonas putida bacteremia.
Findings:
- Intravenous (IV) ceftazidime was administered as treatment.
- The treatment resulted in the clearance of Pseudomonas putida from blood cultures.
- The patient exhibited significant clinical improvement.
Implications:
- This case highlights the importance of considering Pseudomonas putida in bacteremia, especially in immunocompromised patients with soft tissue involvement.
- Broad-spectrum antibiotics, specifically fourth-generation cephalosporins like ceftazidime, are effective in treating Pseudomonas putida bacteremia.
- Early diagnosis and appropriate antibiotic therapy are crucial for favorable outcomes in patients with Pseudomonas putida bacteremia.
