A 65-year-old man with an abdominal aortic endoprosthesis presented with fever without other symptoms. Investigations revealed Lactobacillus casei bacteraemia. The Lactobacillus graft infection was at first successfully treated by antibiotic therapy. However, during follow-up a relapse occurred, and after surgical replacement of the graft the patient was cured. At surgery an aortoenteric fistula was found as source of the infection.
