A Case of Christensenella hongkongensis and Bacteroides fragilis Group Bacteremia Secondary to Diverticulitis

Kento Goto et al. Cureus. .

Abstract

Anaerobic Gram-positive rod bacteremia is typically linked to organisms such as Clostridium perfringens or contamination, but can occasionally be caused by less common microorganisms. Here, we present a case of bacteremia caused by Christensenella hongkongensis, identified through 16S rRNA gene sequencing, in a 79-year-old man who developed a fever during hospitalization for diabetes education.

Keywords: 16s rrna gene sequence; anaerobic gram-positive rod; bacteremia; diabetes mellitus; enterobacteria.
