title: [Detection of a rotavirus G9P[8] outbreak causing gastroenteritis in a geriatric nursing home].
abstract: BACKGROUND
  The aim of this study was to describe an outbreak of gastroenteritis due to rotavirus in a geriatric nursing home.
  
  
  METHODS
  Stool samples from 8 patients were studied. Antigen detection was carried out by ELISA, and molecular typing was performed by RT-PCR.
  
  
  RESULTS
  Rotavirus antigen was detected in 6 patients. Typing demonstrated a common genotype (G9P[8]).
  
  
  CONCLUSIONS
  The outbreak detected in elderly persons suggests a loss of immunity with age or a lack of protection against an emergent genotype.
