Presentation
A 67-year-old man with no significant past medical history presented to the emergency department with pain, swelling and erythema of the right index finger. He sustained a dog bite the day prior during an altercation between his dog and a stray dog. Blood and wound cultures were collected during surgical debridement and submitted to the microbiology laboratory. The blood cultures were negative. Aerobic cultures of the wound showed many inflammatory cells with no organisms identified on Gram stain (if this organism were seen, it would be a gram-negative coccobacillus). The culture revealed non-hemolytic grey mucoid colonies that grew within 24 hours on sheep blood agar.
