Abstract:
Pasteurella multocida, which colonizes upper respiratory and digestive tracts, is a leading cause of respiratory diseases in many host species. Here, we describe a case of P. multocida pneumonia with hemoptysis. A 72-year-old female diagnosed with bronchiectasis with a 36-year history presented with a worsened infiltrative and granular shadow in the lower right lobe and lingular segment. Bronchial lavage fluid culturing suggested Pasteurella pneumonia. P. multocida was confirmed by 16S rRNA sequencing. The patient was readmitted to our hospital because of hemoptysis, and she was treated successfully with antibiotic therapy. The possibility of P. multocida infection must be considered in patients who own pets.
Insights
Pasteurella multocida pneumonia can cause hemoptysis in patients with bronchiectasis. Pet ownership may increase the risk of this Pasteurella multocida infection.
Area of Science:
- Veterinary Medicine
- Human Medicine
- Infectious Diseases
Background:
- Pasteurella multocida is a common bacterium colonizing animal and human respiratory and digestive tracts.
- It is a significant cause of respiratory disease across various host species.
Observation:
- A 72-year-old female patient with a 36-year history of bronchiectasis presented with worsening infiltrates in her right lower lobe and lingular segment.
- Bronchial lavage fluid cultures indicated Pasteurella pneumonia, later confirmed as Pasteurella multocida via 16S rRNA sequencing.
Findings:
- The patient experienced hemoptysis, a symptom not typically highlighted in Pasteurella multocida pneumonia cases.
- Successful treatment was achieved with antibiotic therapy.
Implications:
- This case highlights Pasteurella multocida pneumonia as a potential cause of hemoptysis, particularly in immunocompromised individuals or those with underlying lung conditions like bronchiectasis.
- Clinicians should consider Pasteurella multocida infection in patients presenting with respiratory symptoms, especially if they own pets, as this can be a transmission route.
