Isolation of Xanthobacter Species and Bordetella trematum in a Patient With Polymicrobial Peritonitis.

We describe a case of peritonitis secondary to perforated appendicitis in which Xanthobacter species and Bordetella trematum were isolated from the peritoneal fluid associated with Klebsiella pneumoniae. Species of the genus Xanthobacter have never been isolated from human samples to date, and human infections caused by B. trematum are very rare. The patient was cured after surgery and treatment with piperacillin/tazobactam and ciprofloxacin. The clinical significance of Xanthobacter species and B. trematum remains unclear in our case. Further studies would be necessary to know the pathogenicity of these bacteria in human infections. Copyright (C) 2017 Wolters Kluwer Health, Inc. All rights reserved.
