    摘要:

    目的 研究河南省2016—2020年食品污染科瓦利斯沙门氏菌及食源性疾病的溯源状况。方法 2016—2020年河南省食品中分离出22株科瓦利斯沙门氏菌,从腹泻患者粪便中检出5株科瓦利斯沙门氏菌。参照国家食品安全风险监测手册进行血清分型、药敏试验和脉冲场凝胶电泳(PFGE)分子分型,PFGE和药敏数据使用BioNumerics 7.6软件包进行聚类分析。结果 22株科瓦利斯沙门氏菌均来生鲜禽肉食品。从耐药结果来看,食品来源的菌株多重耐药现象不是十分严重,而腹泻患者来源的菌株耐药谱比较复杂,有敏感株存在,也有2株对13种抗生素耐药的超级耐药菌出现;从PFGE分子分型结果来看,同一时期同一区域的食品株之间有相似度很高的现象出现,提示了污染食品在夏季某一区域有聚集的可能。从腹泻患者株和食品株的比对溯源来看,没有食品直接引起的疾病发生,可能是经过一定的传播途径后才致病的。结论 食品安全风险监测数据可以给市场监督提供有效的线索,耐药监测和分子分型技术的普及和应用推动了食源性疾病的溯源和精准化预防,更大限度地实现了疾病预防和保护健康的目标。

    Abstract:

    Objective To study the traceability status of food pollution and foodborne diseases caused Salmonella covalisS.covalis) in He’nan province from 2016 to 2020.Methods 22 strains of S.corvallis from foods and 5 strains from diarrhea patients were isolated from 2016 to 2020 in He’nan Province. Serotyping, drug susceptibility test and PFGE molecular typing were carried out according to the National Food Safety Risk Monitoring Manual. PFGE and susceptibility data were clustered using BioNumerics 7.6 software package.Results 22 strains of foodborne S.corvallis were all from fresh meat. According to results of drug susceptibility test, the multiple drug resistance of foodborne strains was not very serious, while the drug resistance spectrum of strains from diarrhea patients was complex, some were sensitive strains and two strains of them were super resistant bacteria with 13 multiple drug resistance. According to the results of PFGE molecular typing, there were high similarities among food strains in the same region in the same period, suggesting the probability of aggregation of contaminated food in a certain area in summer. According to the comparison and tracing of diarrhea patient strains and food strains, there was no disease directly caused by food, and the disease was caused probably after transmission.Conclusion Food safety risk monitoring data can provide effective clues for market supervision, the popularization and application of drug resistance monitoring and molecular typing technology has promoted the traceability and precise prevention of foodborne diseases, and greatly achieved the goals of disease prevention and health protection.
