2010-2011年青海省传染病技术平台腹泻症候群监测结果分析

Monitoring results analysis of pathogens for diarrhea syndrome by infectious disease technical platform in Qinghai province during 2010- 2011

目的了解青海省腹泻症候群细菌性致泻性病原菌谱的分布特点及病原谱构成，为制定预防措施提供科学依据。方法收集2010年5月～2011年12月青海省2所哨点医院共304例腹泻患者的粪便标本，增菌培养后，可疑菌株用VITEKII全自动细菌鉴定仪和血清学诊断方法进行鉴定。结果304份粪便标本中共分离出52株菌株，分离率为17．11％，其中沙门菌15株、致泻性大肠埃希菌株6株、志贺菌25株、小肠结肠炎耶尔森菌2株、副溶血弧菌1株、嗜水气单胞菌1株、EHEC0157H72株；弯曲菌未检出。结论志贺氏菌、沙门氏菌为青海省细菌性腹泻病人的主要病原菌，婴幼儿是高发人群，加强监测和防治仍是今后的工作重点。

Objective To understand bacterial diarrhea syndrome of the distribution characteristics of pathogens spectrum in Qinghai province, to provide scientific basis for making preventive measures. Methods Collected samples from sentinel hospitals in Qinghai province of May, 2010 - December 2011 a total of 304 cases of pa- tients with diarrhea faecal specimens, after the enrichment culture, suspicious strains with VITEKII automatic bacteria identification and serological identification diagnosis method. Results 304 stool specimens from 52 strains was isolated, the separation rate was 17.11% , among them 15 strains were salmonella, cause diarrhea 6 strains of e. coli and strain, shigella 25 strains, enterocolitis coulson 2 strains, vice hemolysis 1 strain vibrio, heavy moisture 1 strain of bacterium, 2 strains of EHEC O157H7, bending bacteria is not found. Conclusions Shigella and salmonella are main pathogen of bacterial diarrhea patients, infant is high - risk groups, strengthen the monitoring and control is still the key point in the future.
