title: [Isolation of Yersinia enterocolitica 0:8 in Spain].
abstract: BACKGROUND
  We presented three cases of enterocolitis due to Yersinia enterocolitica 0:8.
  
  
  METHODS
  We use common isolation media, pathogenicity markers and plasmid analysis.
  
  
  RESULTS
  The study of genetic and biochemical characteristics of the strains showed that they belonged to 1B biotype, 0:8 serotype, and that they not carry the virulence plasmid. However, they have pathogenicity markers that were considered typical of highly virulent strains.
  
  
  CONCLUSIONS
  This are the first isolations of this particular serotype in Spain and they showed, as it happens in other European countries, the spread of serotype 0:8 around the world.
