Isolation of Serratia plymuthica from a human burn site.

The saprophytic bacterium Serratia plymuthica was recovered from a facial wound (burn) site of a pediatric patient. The clinical significance of the organism was undetermined due to its apparent eradication from this location by therapy with topical 1% silver sulfadiazine. Seeding of the burn with S. plymuthica may have occurred from contaminated moisture sometimes found on and around steam radiators.
