title: [Tracing to the source of staphylococcus aureus isolates from ice cream].
abstract: OBJECTIVE
  To investigate the contamination of Staphylococcus aureus isolates in ice cream by phenotypic typing and molecular typing.
  
  
  METHODS
  The Staphylococcus aureus isolates were separated from ice cream, filler, cutter, salves and material. The separated isolates were characterized by drug-resistance, staphylococcal enterotoxin (SEA-E), SE (A-E, G-J) genes and pulsed-field gel electrophoresis (PFGE) types.
  
  
  RESULTS
  Two Staphylococcus aureus isolates were separated, one from ice cream, another from cutter. Their characteristics of drug-resistance, staphylococcal enterotoxin (SEA-E), SE (A-E,G-J) genes and PFGE type were the same.
  
  
  CONCLUSIONS
  The two Staphylococcus aureus isolates were the same clone. The contaminated Staphylococcus aureus isolates could be traced to the contaminated cutters.
