title: Citrobacter koseri osteomyelitis in an infant.
abstract: A 3-week-old infant developed left shoulder swelling and was found to have septic arthritis and osteomyelitis of the humerus caused by Citrobacter koseri (formerly C. diversus). Citrobacter species are Gram-negative rods that are best known for their propensity to cause neonatal meningitis, ventriculitis and concomitant brain abscess. Non-central nervous system infections are rare. The present case illustrates that neonatal osteomyelitis caused by unusual organisms can present to pediatricians in an inner-city setting, and can respond favorably to surgical and medical management.
