2003—2007年西安市感染性腹泻监测点细菌病原学监测结果

Bacteriological Surveillance and Analysis of Infectious Diarrhea Monitoring Points in Xian City during 2003—2007

目的了解并掌握西安市腹泻病的发生、流行特征、变化趋势及细菌性病原分布特点,为制定预防措施和临床治疗提供参考依据。方法2003—2007年对西安市腹泻病哨点监测医院中就诊的急性腹泻病患者,用肛拭子采集粪便标本进行增菌后,分别接种4种培养基(碱性蛋白胨水、SS、EMB、中国蓝平板)作霍乱弧菌、沙门菌、志贺菌以及致泻性大肠埃希菌的检验。结果从1310份粪便样本中,检出各种病原菌90株,检出率6.87%。其中志贺菌占85.56%,还有沙门菌、大肠埃希菌和副溶血弧菌。结论2003—2007年检出的阳性菌群中主要以志贺菌为主,初步揭示了西安市细菌性腹泻病原谱。

[ Objective ] To understand the occurrence, epidemic features, change trend and bactericidal pathogenic distribution fea- tures of diarrhea in Xi＇an city, and provide reference for prevention measures and clinical treatments. [ Methods] Stool specimens were collected from the patients who were diagnosed acute diarrhea in sentinel surveillance hospital in Xian city from 2003 to 2007. After enrichment, the specimens were inoculated four kinds of medium （ alkaline peptone water, SS, EMB, China Blue Plate） for vibrio cholera, Salmonella, Shigella, diarrhea and Escherichia coli tests. [ Results ] Of 1310 stool specimens, 90 （ 6.87% ） strains of various pathogens were detected, among which Shigella accounted for 85.56% , salmonella, E. coli and vibrio parahaemolyticus also existed. [ Conclusion] Shigella, which was the primary positive flora detected annually during 2003-2007, initially revealed the spectrum of pathogenic bacterial diarrhea.
