目的 旨在监测中国食源性致病菌及其耐药性。方法 中国疾病预防控制中心营养与食品安全所建立的全国食品污染物监测网的食源性致病菌监测部分 ,2 0 0 1年在全国 11个省市设点采样并检测了七大类 (生肉、熟肉、生奶、冰激淋、酸奶、水产品和蔬菜 )共 4 0 34份样品。结果 沙门氏菌、大肠杆菌O15 7∶H7和单核细胞增生李斯特氏菌 ,总阳性率 5 5 0 %。其中沙门氏菌 3 32 % ,单核细胞增生李斯特氏菌 1 2 9% ,大肠杆菌O15 7∶H70 82 %。生肉的污染情况最为严重 ,阳性率 12 96 %。共分离出沙门氏菌 137株 ,德比沙门氏菌、阿贡纳沙门氏菌、肠炎沙门氏菌、里定沙门氏菌、鸭沙门氏菌、明斯特沙门氏菌及鼠伤寒沙门氏菌 7种血清型占 80 %。结论 沙门氏菌的血清型分布和耐药性各个省不同。自生、熟肉中分离到O15 7∶H7的强毒株。对分离的沙门氏菌、大肠杆菌检测了 14种抗生素的耐药性 ,结果表明沙门氏菌和大肠杆菌中都有多重耐药株。
The purpose is to monitor food-borne pathogens and their resistance in China. Methods The foodborne pathogens monitoring part of the National Food Contaminant Monitoring Network established by Nutrition and Food Safety of China Center for Disease Control and Prevention was set up in 11 provinces and cities nationwide to sample and test seven major categories Raw meat, cooked meats, raw milk, ice cream, yogurt, aquatic products and vegetables). Results Salmonella, Escherichia coli O15 7: H7 and Listeria monocytogenes, the total positive rate of 55.0%. Among them, Salmonella 3 32%, Listeria monocytogenes 122%, Escherichia coli O15 7:H70 82%. The most serious pollution of raw meat, the positive rate of 12 96%. A total of 137 strains of Salmonella, Salmonella Derby, Salmonella Argona, Salmonella enteritidis, Salmonella enteritidis, Salmonella enterica, Salmonella muenster and Salmonella typhimurium were isolated, accounting for 80%. Conclusion Salmonella serotype distribution and drug resistance in different provinces. Inborn, cooked meat was isolated from virulent strain O15 7:H7. For isolated Salmonella, E. coli was tested for resistance to 14 antibiotics and the results showed that there were multiple drug-resistant strains in both Salmonella and E. coli.
