title: [The relationship between esp and the ability of biofilm formation in enterococci from the intestinal tract of normal people].
abstract: OBJECTIVE
  To investigate the biofilm formation of Enterococci from the intestinal tract of normal people, to study the relationship between esp and the ability of biofilm formation in Enterococci.
  
  
  METHODS
  PCR was applied to detect the esp gene in 84 isolates. And the biofilm formation was performed in 96 well polystyrene plates.
  
  
  RESULTS
  The detection rate of esp in Enterococci was 14.3%, the rate of biofilm formation was 25.0%, the rate of biofilm formation of esp positive isolates was 83.3%, and that of esp negative isolates was 15.3%.
  
  
  CONCLUSIONS
  Biofilm formation is not very common in Enterococci from the intestinal tract of normal people, esp is an important factor of biofilm formation, and the ability of biofilm formation is not limited to the esp positive isolates.
