Background:
Pseudomonas fluorescens (P. fluorescens) has been detected in respiratory samples from patients. However, no previous reports have been published about these P. fluorescens cultures from lung tissues.
Case Presentation:
Here, we report a case of pneumonia caused by P. fluorescens. P. fluorescens was identified from lung biopsy specimens for the first time in this case. According to the antibiotic susceptibility testing (AST) of P. fluorescens, the patient was given ciprofloxacin treatment. The temperature of the patient then returned to normal. Chest CT examination revealed improvements in pulmonary inflammation.
Conclusions:
These findings suggest that the patients with pneumonia caused by P. fluorescens should be treated in a timely manner according to the AST results.
Insights
Pseudomonas fluorescens pneumonia is rare but treatable. This case highlights the first isolation of P. fluorescens from lung tissue, emphasizing timely antibiotic susceptibility testing for effective patient recovery.
Area of Science:
- Medical Microbiology
- Pulmonology
- Infectious Diseases
Background:
- Pseudomonas fluorescens is typically found in respiratory samples.
- No prior reports documented P. fluorescens cultures originating from lung tissues.
Observation:
- A case of pneumonia caused by P. fluorescens is presented.
- P. fluorescens was identified in lung biopsy specimens, marking a novel finding.
- Antibiotic susceptibility testing guided treatment with ciprofloxacin.
Findings:
- The patient's temperature normalized following ciprofloxacin treatment.
- Chest CT scans indicated improvement in pulmonary inflammation.
- Successful treatment of P. fluorescens pneumonia was achieved.
Implications:
- This case underscores the importance of prompt diagnosis and treatment for P. fluorescens pneumonia.
- Antibiotic susceptibility testing is crucial for selecting effective therapies.
- Further research into P. fluorescens lung infections may be warranted.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
