A case of infection with Corynebacterium ulcerans (C. ulcerans), resulted in the sudden death of a previously healthy 73-year-old woman. Death from Corynebacteriwm diphtheriae (C. diphtheriae) infection is well-documented.

The production of the bacteriocin ulceracin 378 Bacteriocins are bacterial products which are distinguished from "classical" antibiotics by their narrow spectra of activity and their protein nature (1, 6). The first and best studied of the bacteriocins are the colicins, bacteriocins produced by certain strains of Enterobacteriaceae (15,16). Thibaut (19) and several other investigators have described the elaboration of bacteriocinlike substances by corynebacterium strains (5,11,14,18,20
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
