Chryseobacterium indologenes in a woman with metastatic breast cancer in the United States of America: a case report

INTRODUCTION: We report the seventh case of Chryseobacterium indologenes occurring in the United States of America. C. indologenes is seldom isolated from clinical specimens but has caused hospital-acquired infections in Taiwan and rarely elsewhere. CASE PRESENTATION: A 32-year-old Caucasian woman with metastatic breast cancer presented to a hospital emergency department with bilateral radiation-induced pleural effusions and respiratory failure. The patient was hospitalized and ventilated for 26 days; tracheal aspirates collected on ventilation days 24 and 26 grew C. indologenes. The patient subsequently died as a result of worsening ventilator-associated pneumonia and stage IV breast cancer. CONCLUSIONS: C. indologenes infection should be considered for hospitalized patients with a history of malignancy, especially those with indwelling devices and antibiotic use for >14 days.
