Cutaneous Listeriosis in a Veterinarian with the Evidence of Zoonotic Transmission – A Case Report



A case of Listeria monocytogenes skin infection in a man is presented. A 54-year-old male veterinary practitioner developed pustular changes on the skin of arms and hands after assisting with the delivery of a stillborn calf. Listeria monocytogenes was isolated from the skin lesions on the arms and from the bovine placenta. Listeria monocytogenes isolates were serotyped and genotyped with pulsed-field gel electrophoresis (PFGE) to confirm the suspected transmission of the pathogen from animal to human. All isolates were of serotype 4b with identical pulsotype. To the best of our knowledge, this is the first case of cutaneous listeriosis in which the evidence for zoonotic transmission of L. monocytogenes is supported by genotyping methods.
