Pasteurella multocida pneumonia with hemoptysis: A case report

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.
