Abstract
Morganella morganii is a member of Enterobacteriaceae family, whose natural habitat is the human gastrointestinal tract. It rarely causes infection alone and is generally encountered in immunosuppressed patients. Osteoarticular pathologies are not commonly observed with Morganella morganii and infections by it have high mortality rate. Biofilm colonization is a causative factor behind the chronicity and/or refractoriness of certain infections. Biofilms colonize on inert medical devices, prosthesis, fibrosed tissues, sinus tracts as well as dead bones as in case of chronic osteomyelitis. Morganella morganii is not a common pathogen to produce biofilm. In this case report, we present a 56-year-old male patient with chronic osteomyelitis of right proximal tibia caused by biofilm producing strain of Morganella morganii, following trauma.
