About: Bumblefoot (infection)

Bumblefoot (ulcerative pododermatitis) is a common bacterial infection and inflammatory reaction that occurs on the feet of birds, rodents, and rabbits. It is caused by bacteria, namely species of Staphylococcus, Pseudomonas, and Escherichia, with S. aureus being the most common cause of the infection. The aforementioned opportunistic bacteria occur naturally in the animal's environment, and infection occurs when one or a combination of these enters the body through a scrape or cut in the skin. Bumblefoot can take various forms, but it usually looks like an abscess-like swelling with a central, dark-colored scab that may or may not ooze. Sometimes, this swollen bump contains pus or cottage cheese-like material. Alternately, the swelling could contain a hard lump when these materials harden
