an unusual necrotic myositis by clostridium perfringens in a german shepherd dog: a clinical report, bacteriological and molecular identification

clostridial myositis, considered to be rare in pet animals, is an acutely fatal toxaemic condition. some species of clostridia are responsible for necrotic myositis. a 2-year-old male german shepherd dog was admitted with non-weight bearing lameness and massive swelling of the left hind limb. clostridium perfringens type a with alpha toxin was diagnosed as a pathogenic agent. based on the history, the bacteria were introduced inside the tissue via contaminated needle following intramuscular injection. urgent medical therapy followed by surgical intervention was performed. the dog was discharged completely healthy after hospitalization for four weeks. the objective of this report was to describe necrotic myositis in a dog with an emphasis on clinical signs and treatment as well as bacteriological and molecular identification of the micro-organism. because of the fatal entity of the disease, prompt diagnosis as well as proper and urgent treatment is very important for successful therapy.
