Salvage of upper extremity in an aggressive case of Pasteurella multocida infection.

Pasteurella multocida is a small, anaerobic and Gram-negative coccobacillus which is part of the usual saprophyte flora of some mammals, especially among cats and dogs. The most common clinical manifestations occur in soft tissue, in the form of cellulitis, septic arthritis and tenosynovitis. We present a case of an invasive soft tissue infection by P multocida that required several wide debridements and antibiotherapy to save the extremity, emphasizing the usefulness of a complete anamnesis and the aggressive treatment needed.
