2009-2014年浙江省余姚市志贺菌菌型分布及毒力基因分析

Serotypes and virulence genes of Shigella in Yuyao, Zhejiang, 2009-2014

  • 摘要: 目的 了解近年来浙江省余姚市志贺菌菌型变化及毒力基因分布特征。方法 对2009-2014年监测到的82 株志贺菌进行血清分型,采用6对引物IpaH、ial、set1A、set1B、sen、virA分别对志贺菌中毒力相关基因进行检测。结果 2009-2014年共检出收集到志贺菌株82株,以宋内志贺菌(42.5%) 和福氏志贺菌(57.5%)为主。ipaH、ial基因的携带率为100%,set1A、set1B、sen、virA基因的携带率分别为79.3%、76.8%、96.3%和91.4%,set1基因在福氏志贺菌的携带率明显高于宋内志贺菌。结论 余姚市流行的志贺菌优势血清型每年都有变化,毒力相关基因不同菌型之间存在差异。

     

    Abstract: Objective To understand the serotypes and virulence gene carriage of Shigella in Yuyao, Zhejiang province. Methods Serotyping was conducted for 82 Shigella strains isolated from diarrhea patients during 2009-2014, and 6 pairs of primers (ipaH, ial, set1A, set1B, sen and virA) were designed for the detection of Shigella virulence genes. Results Among the 82 Shigella strains, Shigella sonnei accounted for 42.5% and Shigella flexneri accounted for 57.5%. The carriage rates of IpaH, ial gene were 100%, and the carriage rates of set1A, set1B, Sen, virA genes were 79.3%, 76.8%, 96.3% and 91.4%, respectively. The positive rate of Set1 gene in Shigella flexneri was significantly higher than that in Shigella sonnei. Conclusion Predominant Shigella serotype varied with year, and differences in virulence gene carriage were found among the Shigella strains with different serotypes in Yuyao.
