Toxigenic Corynebacterium ulcerans in human and non-toxigenic Corynebacterium diphtheriae in cat

Abstract

Corynebacterium diphtheriae and Corynebacterium ulcerans are rarely isolated from clinical samples in Belgium. A case of toxigenic C. ulcerans in a woman is described, which confirms that this pathogen is still present. During investigation of the patient's cats, only a non-toxigenic toxin-bearing C. diphtheriae strain was detected.
