Isolation of Pasteurella pneumotropica in a Hand Phlegmon Following a Human Bite

Pasteurella is a commensal microorganism found in the mucous membranes of the upper respiratory and digestive tracts of mammals and birds and it rarely affects humans. Human pasteurellosis typically results from infection through bites or scratches from animals, with dogs and cats being the most common sources. However, various vertebrates, such as rats, rabbits, tigers, and lions, can also transmit the infection. We report a case involving a young woman who developed a hand phlegmon on her right forearm following a rare and unusual human bite during a brawl. Her condition improved after both surgical and medical treatment.
