Pasteurella multocida infection, a rare cause of mycotic abdominal aortic aneurysm

A 64-year-old man was admitted with abdominal pain 6 weeks after treatment with intravenous flucloxacillin for cellulitis of his right leg. Urgent operation was necessary for a mycotic aneurysm of the abdominal aorta due to infection with Pasteurella multocida, a microorganism residing in the oral cavity of domestic animals that very rarely causes infection of native arteries or grafts. The aorta was repaired with a rifampin-coated tube graft. Despite postoperative duodenal perforation, abdominal Candida infections, wound dehiscence, and renal insufficiency, the patient is alive I year postoperatively. (J Vase Surg 2009;50:1496-8.)
