【Objective】The distribution characteristics and multiple drug resistance of staphylococcal enterotoxins(SEs)gene isolated from yak meat in Lhasa,Tibet were studied in order to provide scientific basis for the rapid identification and control of SEs in Staphylococcus aureus isolated from yak meat.【Method】S. aureus was isolated from yak meat sample in Lhasa by the Baird-Parker chromogenic media screening and Nuc gene PCR amplification. The distribution characteristics of nine common SEs genes in S. aureus wer...
