Summary
Pasteurella multocida (P. multocida) can cause respiratory infections in individuals with chronic lung conditions like bronchiectasis. This case highlights the importance of considering P. multocida in pulmonary disease management.
Area of Science:
- Microbiology
- Pulmonology
Background:
- Pasteurella multocida (P. multocida) is a known animal pathogen causing hemorrhagic septicemia.
- Human infections typically manifest as skin abscesses or septicemia following animal contact.
- Pulmonary P. multocida infections are uncommon, especially in Japan, often occurring in patients with chronic lung diseases.
Observation:
- An 80-year-old female with a history of bronchiectasis presented with productive cough, bloody sputum, and fever.
- Chest X-ray revealed atelectasis and severe bronchiectasis.
- P. multocida was isolated from sputum samples during two separate episodes of illness.
Findings:
- Chemotherapy with CTM led to clinical improvement in the initial episode.
- Recurrent infection showed significant bacterial load (1 x 10(8)/ml) in sputum.
- The patient experienced a second symptomatic episode with P. multocida isolation.
Implications:
- Increasing prevalence of chronic respiratory diseases necessitates awareness of P. multocida as a potential pathogen.
- P. multocida should be considered in the differential diagnosis for pulmonary infections in patients with underlying lung conditions.
- This case underscores the importance of recognizing P. multocida's role in exacerbating chronic pulmonary diseases.
