衢州地区2007～2008年菌痢分离株的血清分布

Distribution of serotyping of Shigella in Quzhou from 2007 to 2008

目的：掌握衢州地区细菌性痢疾的血清分布特征，为细菌性痢疾的防治提供依据。方法：采用《全国细菌性痢疾监测方案》提供的方法，对衢州地区所辖县、市、区送检疑似阳性菌痢菌株进行复核鉴定，并对志贺菌进行血清学分型。结果：68例送检菌株中共鉴定出志贺菌60株，符合率为88．24％（60／68），其中宋内26株，福氏2a共2株，福氏1a共1株，福氏2b共1株，福氏4c共30株。结论：2007～2008年衢州地区志贺菌引起的菌痢中，血清型多样，且以福氏4c为主，应引起重视。

Objective：To discover the etiological characteristics of Shigella spp. in Quzhou city, thus providing suggestion for shigellosis prevention. Methods： Positive Shigella isolates from the surveillance sites in Quzhou city were systematically re - identified and serotyped according to national protocol of shigellosis surveillance. Results ： The 68 positive isolates were re - identified, 60 ShigeUa strains were confirmed, the postive was 88.24% （60/68）, including 26 S. sonnei strains, 2 S.flexneri 2a strains, 1 S.flexneri 1 a strains, 1 S.flexneri 2b strains, 30 S.flexneri 4c strains. Conclusion：The serotyping is complex and the dominant Shigella isolates in Quzhou from 2007 to 2008 are S.flexneri 4c.
