Recurrent Osteomyelitis Caused by Infection with Different Bacterial Strains without Obvious Source of Reinfection

Abstract
Recurrence of osteomyelitis by the same bacterial strain is well known. We report three patients with a second episode of osteomyelitis at the same site caused by different strains of bacteria from the original. Formerly infected and altered bone surface might present a region of diminished resistance for a new infection.
