门诊细菌性痢疾志贺菌检测结果分析

Shigellae Isolation in Bacillary Dysentery Episodes in Outpatient Settings

目的探讨与门诊细菌性痢疾临床诊断病例的粪便培养志贺菌阳性率有关的因素。方法回顾性分析453例细菌性痢疾临床诊断病例便培养志贺菌结果及其流行病学和临床特征。结果便培养志贺菌阳性率随患者年龄、职业、发病季节、每日腹泻次数、发热程度和粪便外观不同而有变化趋势[P值分别为0.030、0.001、0.029、0.017(福氏志贺菌)、0.024(宋内志贺菌)、0.002和0.011]。结论门诊细菌性痢疾临床诊断病例粪便培养志贺菌阳性率可能与患者年龄、职业、发病季节、腹泻和发热程度、粪便外观有关。

Objective To discuss associated factors of Shigella positivity rate in stool specimens of the bacillary dysen- tery patients clinically diagnosed in outpatient settings. Methods The stool culture result for Shigella, its epidemiolagical and chnical features of 453patients clinically diagnosed as having bacillary dysentery in outpatient settings were retrospectively analyzed. Results A trend was found that Shigella positivity rate varied form age （ P = 0. 030） , occupation （ P = 0. 001 ） , season （ P = 0. 029 ） , diarrhea times in a 24 - hour period （ P = 0. 017 in Shigella flexneri or P = 0. 024 in Shigella sonnei）, fever （ P =0. 002） , visible fecal blood, pus and mucus （P = 0. 011 ）. Conclusion The Shigella positivity rate in stool specimens in outpatient settings is associated with age, occupation, season, degree of diarrhea and fever, and fecal appearance.
