Liver abscess due to Neisseria sicca after repeated transcatheter arterial embolization

Abstract

Neisseria sicca is rarely associated with clinical infections and to the authors' knowledge this organism has not been reported as a causative agent of infected biloma (liver abscess). A case of a diabetic man with infected biloma due to N. sicca after repeated transcatheter arterial embolization for hepatocellular carcinoma is reported. The patient was successfully treated with intravenous cefotaxime and metronidazole. The biochemical profile and 16S rRNA gene partial sequencing results of the isolate were in agreement with those of N. sicca.
