Osteomyelitis Due to Citrobacter koseri Infection in a Diabetic Patient

Abstract

Citrobacter infections are reported in neonates and immunocompromised patients most commonly. Citrobacter koseri (diversus) is an important cause of neonatal meningitis and brain abscess formation. But osteomyelitis is a rare condition and very few cases were reported. We described a 68-years-old man with diabetes mellitus who had 1st metatarsal osteomyelitis due to Citrobacter koseri. Intravenous treatment with piperacillin-tazobactame was administered for 3 weeks and the wound was recovered completely. Citrobacter koseri can be a cause of osteomyelitis in patients with underlying predisposing factors and bone cultures should be evaluated to detect probable pathogens and determine proper antimicrobial therapy.
