A Chronic Respiratory Pasteurella multocida Infection Is Well-Controlled by Long-Term Macrolide Therapy

Abstract

A 57-year-old woman with severe bronchiectasis frequently received antibiotics, including penicillin, for acute exacerbations due to Pasteurella multocida. Although the bacteria showed a decrease in antibiotic susceptibility, her symptoms and X-ray findings became stable, and severe exacerbations were not observed for the last few years after a low-dose erythromycin treatment was started. The development of a respiratory infection with Pasteurella multocida is relatively uncommon, but it can be controlled by immunomodulation which is associated with long-term macrolide therapy.
