Septic Arthritis and Osteomyelitis in Finger Caused by <i>Mycoplasma phocimorsus</i> from Brown Bear, Alaska, USA

Mycoplasma phocimorsus is an identified zoonotic agent of musculoskeletal infections. Osteomyelitis developed in a patient after injury sustained while skinning a bear, and he experienced delayed diagnosis after ineffective treatments. Clinicians should use doxycycline or moxifloxacin therapy in treatment-refractory cases with exposure to seals, cats, or bears while awaiting molecular diagnostics results.
