Corynebacterium striatum is a bacterium that is a member of the Corynebacterium genus.[1] It is classified as non-diphtheritic.[2] The bacterium is a gram-positive prokaryote that assumes a 'club-like' morphology, more formally known as a corynebacteria structure.[1][3][4] It is non-lipophilic and undergoes aerobic respiration. It is a facultative anaerobe. It is catalase negative and is an oxidase positive glucose and sucrose fermenter.[1][3]

It is generally found as a ubiquitous microorganism and as a commensal of humans that colonises the nasopharynx.[1][5] It has recently been recognised as an emerging pathogen although the genus of Corynebacterium is not usually considered to be pathogenic. Particularly in the context of human disease, Corynebacterium striatum is generally considered an opportunistic pathogen. This is particularly in a nosocomial setting.[5][6] It has been recorded to infect the skin and the upper and lower respiratory tract and even disseminate - resulting in sepsis. Recent interest has been sparked in the microorganism, as it is known to be resistant to and gaining resistance to many antibiotics.[7]
