本文对一种新致泻性大肠杆菌 :产志贺样毒素且具侵袭力大肠杆菌 (ESIEC)进行了调查研究。共检测不同来源的标本 90 8件 ,检出ESIEC菌株 10 4株 ,检出率为 11 4 5%。调查证实ESIEC菌株广泛存在于人体、外环境及动物体内 ,以腹泻患者检出率最高达 32 4 3 %。对 68株ESIEC菌株用irp - 2探针杂交阳性 8株占 11 7% ,进一步用irp - 2基因PCR鉴定阳性 5株占 7 4 % ,表明ESIEC是一类新的致腹泻的病原微生物 ,广泛存在于三峡地区 ,对ESIEC的研究具有重要的流行病学意义。
In this paper, a new digesting Escherichia coli: Shiga-like toxin and invasive E. coli (ESIEC) were investigated. A total of 908 specimens from different sources were detected, 104 strains of which were detected by ESIEC, the detection rate was 11 45%. The survey confirmed that ESIEC strains are widely found in the human body, external environment and animal body, and the detection rate of diarrhea patients is up to 32 4 3%. Eight of 68 ESTEC strains were positive for hybridization with irp - 2 probe, accounting for 11.7% of the total, and 7 positive for 5 strains identified by irp - 2 gene PCR, indicating that ESIEC is a new type of pathogenic microorganism causing diarrhea. Exist in the Three Gorges area, the study of ESIEC has important epidemiological significance.
