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

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.
