2018-2020年浙江省湖州市食源性疾病监测结果分析

Surveillance results of foodborne diseases in Huzhou, Zhejiang, 2018–2020

  • 摘要:
      目的   了解浙江省湖州市食源性疾病的感染状况和流行病学特征。
      方法   收集湖州市2018 — 2020年6家食源性疾病监测哨点医院(重点监测点和常规监测点各3家)上送的沙门菌、副溶血弧菌、致泻性大肠埃希菌、志贺菌分离菌株,再对分离菌株进行血清分型和毒力基因检测;采用real-time PCR方法进行诺如病毒核酸检测。
      结果   共检测6783 例腹泻病例标本,检出病原体1373份,检出率为20.24%。 致泻性大肠埃希菌检出率为6.49%,主要以肠聚集性大肠埃希菌和产肠毒素大肠埃希菌为主;副溶血弧菌检出率5.31%,血清分型以 O3∶K6 为主,毒力基因以tdh 为主;沙门菌检出率为2.85%,以鼠伤寒沙门菌为主;诺如病毒阳性率为11.65%,基因型别以GⅡ.2[P16]为主。 致病菌引起的发病高峰在夏季,诺如病毒引起的发病高峰在冬春季, 20~39岁为主要感染人群。
      结论   2018 — 2020年引起湖州市感染性腹泻的病原体为诺如病毒、致泻性大肠埃希菌、副溶血弧菌和沙门菌,发病呈现明显的季节性和年龄分布。 应加强对食源性病原体的监测,有效控制食源性疾病的发生。

     

    Abstract:
      Objective   To discuss the infection status and epidemiological characteristics of foodborne diseases in Huzhou of Zhejiang province.
      Methods   The Salmonella, Vibrio parahaemolyticus, diarrheogenic Escherichia coli strains from 6 sentinel hospitals (3 key surveillance points and 3 routine surveillance points) in Huzhou from 2018 to 2020 were used for serotyping and virulence gene detection;Real-time PCR was conducted for the nucleic acid detection of norovirus.
      Results   A total of 6783 samples of diarrhea cases were detected, and 1373 were pathogen positive, with a detection rate of 20.24%. The detection rate of diarrheogenic E. coli was 6.49%, mainly enteroaggregative E. coli and enterotoxigenic E. coli. The detection rate of V. parahaemolyticus was 5.31%, the main serotype was O3∶K6, and the main virulence genotype was tdh. The detection rate of Salmonella was 2.85%, with S. typhimurium as the main species. The positive rate of norovirus was 11.65%, and the genotype was mainly GⅡ.2[P16]. The incidence peak of pathogenic bacteria infection was in summer, and the incidence peak of norovirus infection was in winter and spring, and people aged 20–39 years were mostly affected.
      Conclusion   The pathogens causing infectious diarrhea in Huzhou from 2018 to 2020 were norovirus, diarrheogenic E. coli, V. parahaemolyticus and Salmonella, and the infection incidence showed obvious seasonal and age distributions. The surveillance for foodborne pathogens should be strengthened to effectively prevent and control the incidence of foodborne diseases.
