'Imported' melioidosis in Germany: relapse after 10 years.

A 62-year-old German patient with insulin-dependent diabetes and diverticulitis was hospitalized for abdominal pain of the left lower quadrant. Further examination revealed an abdominal abscess, which was punctured. Presumptively a Pseudomonas species was identified, but further examination revealed Burkholderia pseudomallei as the causative agent. Most probably this infection was acquired in 1996 during a trip to Thailand, where the patient had been hospitalized. After combined chemotherapy and surgical revision of the abscess, the patient's condition improved. Clinicians and microbiologists have to keep in mind that in some tropical infections such as melioidosis relapse may occur after such a long time.
