目的了解河南省食源性金黄色葡萄球菌和沙门菌的耐药情况,为相关部门政策制定提供依据。方法金黄色葡萄球菌和沙门菌的检测及其药物敏感性试验参照《2010年食源性致病菌工作手册》操作方法进行。结果对2010年检出的46株金黄色葡萄球菌和40株沙门菌分别进行16种抗生素的药物敏感试验,前者对6种抗生素敏感(100%),9种抗生素产生不同程度的耐药(2.17%～76.09%),其中对盘尼西林的耐药率最高,达76.09%,其次是对红霉素的耐药率,达45.65%。后者对1种抗生素敏感(100%),对14种抗生素产生不同程度的耐药(2.5%～62.5%),其中对四环素耐药率最高,达62.5%,其次是对萘啶酸的耐药率,达47.5%。结论河南省食源性金黄色葡萄球菌和沙门菌耐药形势严峻,尤其是沙门菌。
Objective To understand the drug resistance of foodborne Staphylococcus aureus and Salmonella in Henan Province and to provide the basis for policy making by relevant departments. Methods Staphylococcus aureus and Salmonella detection and drug susceptibility testing with reference to the “2010 Foodborne Pathogen Working Manual” method of operation. Results Sixteen antibiotic susceptibility tests were carried out on 46 strains of Staphylococcus aureus and 40 strains of Salmonella isolated in 2010, the former being sensitive to 6 antibiotics (100%) and the other being resistant to 9 antibiotics (2.17 % ~ 76.09%). Among them, the rate of resistance to penicillin was the highest (76.09%), followed by erythromycin (45.65%). The latter was sensitive to one kind of antibiotics (100%) and had different degrees of resistance to 14 kinds of antibiotics (2.5% -62.5%), of which the resistance rate to tetracycline was the highest (62.5%), followed by that of nalidixic acid Drug rates, up 47.5%. Conclusion The resistant situation of foodborne Staphylococcus aureus and Salmonella in Henan Province is severe, especially Salmonella.
