title: [Nosocomial outbreak due to Listeria monocytogenes in a neonatal unit].
abstract: BACKGROUND
  Description of an outbreak of Listeria monocytogenes in a neonatal intensive care unit.
  
  
  METHODS
  A questionnaire, environmental investigation and molecular study were performed.
  
  
  RESULTS
  We identified a nosocomial outbreak of L. monocytogenes, confirmed by the genetic study, in a neonatal intensive care unit. Three infants were affected. Although the transmission mechanism could not be elucidated, cross-infection was strongly suggested.
  
  
  CONCLUSIONS
  Adherence to universal hygiene standards is necessary to avoid nosocomial outbreaks.
