目的 了解济南市2006-2011年志贺菌菌型分布及变迁规律,为细菌性痢疾的预防控制提供依据。 方法 按照《全国细菌性痢疾监测方案》的要求进行采样及系统检测。 结果 福氏志贺菌占72.4%,为优势菌群;各年份中福氏菌所占比重逐步下降,B:D值呈下降趋势;F2a血清型所占比重最大(占27.2%),X、Y变种近年有所增加。 结论 2006-2011年济南市志贺菌以B群和F2a型为主,宋内菌逐渐增加,提示近年来济南地区环境卫生和个人卫生有所改善,同时菌型日渐复杂,应当继续加强细菌性痢疾的监测。
Objective To understand of the predominant group and serotype of Shigella in Jinan from 2006 to 2011 and provide evidence for the prevention and control of bacillary dysentery. Methods The samples were collected to conduct detection according to the requirements of National bacillary dysentery surveillance protocol. Results S. flexneri was the predominant group of Shigella circulating in Jinan during this period, the strains of which accounted for 72.4% of the total isolates detected, but the annual proportion declined gradually. The B to D ratio was in decline. The strains in F2a serotype accounted for the highest proportion (27.2%), the stains in X and Y serogroups increased in recent years. Conclusion The Shigella in F2a serotype in B group was predominant in Jinan during 2006-2011, the proportion of S. sonnei strains detected increased gradually, suggesting the environment sanitation and personnel hygiene were improved in Jinan. Due to the fact of co-circulating of different types of Shigella, it is important to strengthen bacillary dysentery surveillance in the future.
