Skin and Soft Tissue Infections Due to Corynebacterium ulcerans - Case Reports

Abstract

History and clinical findings We report on three patients suffering from skin and soft tissue infections of the legs due to toxigenic Corynebacterium ulcerans strains. In all three patients, there was a predisposition due to chronic diseases. Three patients had domestic animals (cat, dog) in their households. Investigations and diagnosis A mixed bacterial flora including Corynebacterium ulcerans was found in wound swab samples. Diphtheric toxin was produced by the Corynebacterium ulcerans strains in all three cases. Treatment and course In all three patients, successful handling of the skin and soft tissue infections was possible by combining local treatment with antibiotics. Diphtheria antitoxin was not administered in any case. Conclusion Based on a review of the recent literature pathogenesis, clinical symptoms and signs, diagnostics and therapy of skin and soft tissue infections due to Corynebacterium ulcerans are discussed. Corynebacterium ulcerans should be considered as a potential cause of severe skin and soft tissue infections. Occupational or domestic animal contacts should be evaluated.
