Enterobacter hormaechei bloodstream infection at three neonatal intensive care units in Brazil.

Enterobacter hormaechei was defined as a unique species in 1989. We describe six case patients of E. hormaechei bloodstream infection in three neonatal intensive care units in Rio de Janeiro, Brazil. E. hormaechei identification was performed on the Vitek system and confirmed by conventional testing. Strain relatedness was evaluated by pulsed field gel electrophoresis. All children recovered completely. Chart review for previous procedures revealed parenteral nutrition as the only common procedure.
