Septic arthritis caused by Actinobacillus ureae in a patient with rheumatoid arthritis receiving anti-tumor necrosis factor-alpha therapy.
Actinobacillus ureae, formerly known as Pasteurella ureae, is a rare human pathogen. We describe a case of septic arthritis and abscess formation caused by this unusual organism in a patient with rheumatoid arthritis, who was being treated with tumor necrosis factor-alpha inhibitors.
