Corynebacterium jeikeium is a rod-shaped, catalase-positive, aerobic species of Actinomycetota in the genus Corynebacterium. C. jeikeium is pathogenic, typically causing an opportunistic infection seen most frequently in bone marrow transplant patients. C. jeikeium is a strictly aerobic organism and forms tiny grayish white colonies when grown on blood agar. [2]

C. jeikeium is usually susceptible to vancomycin and tetracycline. Resistance to macrolide antibiotics is often encountered.[3]

It can be acquired in hospitals. Its genome has been sequenced.[4]
