Splenic abscess caused by Shigella flexneri and Bacteroides fragilis

Abstract

We report a case of splenic abscess from which only Shigella flexneri (serotype 1a) and Bacteroides fragilis were isolated. The patient was a 59-year-old diabetic female who displayed minimal gastrointestinal symptoms. The S. flexneri isolate was resistant to chloramphenicol and tetracycline. The possible synergistic relationship between the two organisms is discussed.
