Splenic infarction was also suspected during C. tertium bacteremia. C. tertium was identified by using mass spectrometry and 16S rRNA sequencing. This patient was successfully treated with emergency laparotomy and broad-spectrum antibiotics. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
