Subcutaneous abscess caused by Clostridium perfringens and osteomyelitis in a dog

A case of a subcutaneous abscess caused by Clostridium perfringens infection in a five-month-old dog is reported in this study. Clinical examination, radiological findings and cytological analysis of abscess fluid were consistent with Clostridium induced disease. Treatment including drainage of the abscess and antibiotic therapy led to rapid clinical improvement. However, despite aggressive medical therapy and proper wound care, the deep soft tissue infection led to osteomyelitis with premature closure of the growth plates of the tibia and secondary bone shortening. Prolonged treatment with metronidazole and amoxicillin-clavulanic acid resulted in an excellent outcome with normal weight bearing.
