Clinical Characteristics of Corynebacterium Bacteremia Caused by Different Species, Japan, 2014–2020

To determine differences in clinical characteristics of patients with bacteremia caused by Corynebacterium striatum, C. jeikeium, and other species of Corynebacterium, we retrospectively reviewed medical records of patients in Japan who had Corynebacterium bacteremia during January 2014–May 2020.
