Bacteremia Caused by Yokenella regensburgei in a Patient with Diabetes Mellitus

Yokenella regensburgei rarely causes human infections, and there is no strong evidence to support its clinical importance. We report the first case in Japan of bacteremia caused by Y. regensburgei in a patient with diabetic gangrene. A 74-year-old man was admitted to our hospital. He had type 2 diabetes mellitus, and underwent surgical amputation of both lower limbs due to gangrene. Y. regensburgei was isolated from swabbing of the wounds on the limbs and the blood samples. The case was successfully treated by intravenous administration of ampicillin-sulbactam and ceftazidime.
