Achromobacter xylosoxidans in idiopathic cystic bronchiectasis.

This is the first case in the English language describing Achromobacter xylosoxidans in a patient with idiopathic bronchiectasis. A 66-year-old man with bronchiectasis presented with shortness of breath to the emergency department of our institution, a district hospital in the UK. His medications included long-term supplemental oxygen therapy and prophylactic azithromycin. Following 2 days admission to the respiratory unit, his saturations significantly deteriorated, and the patient was admitted to intensive care with type II respiratory failure. Following a week of intubation and ventilation, multidrug resistant A. xylosoxidans was isolated from the tracheal aspiration secretions. The patient recovered after receiving targeted intravenous antimicrobial therapy.
