摘　　要：目的研究餐饮从业人员携带的金黄色葡萄球菌的耐药性及相关基因情况。方法采用药敏试验和基因检测方法,对广西部分餐饮从业人员携带的金黄色葡萄球菌耐药性及其相关基因进行分析。结果从分离的118株金黄色葡萄球菌中检出多重耐药金黄色葡萄球菌(MDRSA)76株,检出率为64.41%。MDRSA耐消毒剂基因qacA/B检出率为42.1%,毒力基因以Tst和Seb为主,检出率分别为17.11%和46.05%。结论餐饮业人员携带的金黄色葡萄球菌中MDRSA占比较高,耐消毒剂基因qacA/B检出率也比较高,提示对餐饮业人员应加强人体带菌情况监管。Objective To investigate multi-drug resistance of Staphylococcus aureus(MDRSA)isolated from catering employees and related genes.Methods Antibiotic susceptibility experiments and gene detection method were performed on all MDRSA isolated from catering employees and related genes.Results 76 strains of MDRSA were detected out from 118 strains of Staphylococcus aureus isolated.The detection rate was 64.41%.The detection rate of qacA/B was 42.1%.The main virulence genes were Tst(17.11%)and Seb(46.05%).Conclusion MDRSA is high in Staphylococcus aureus isolated from catering employees.The detection rate of disinfectant-resistant genes qacA/B is high too.Supervision should be strengthened in catering employees.
