Haemophilus segnis cholecystitis: a case report and literature review

Haemophilus segnis is a normal commensal of the human oropharynx which is occasionally associated with appendicitis, endocarditis or pancreatic abscess. Haemophilus segnis in the gall-bladder from a 58-year-old white female was recently encountered. The patient recovered from surgery without incident. This case is reported because the gall-bladder is now another site which has become infected with this organism. In order to provide guidance to physicians when H. segnis organism is identified, microbiologists should be aware of its behaviour in different sites.
