侵袭性大肠杆菌(Tnteroinvasive Escherichia Coli简称EIEC),是具有侵入上皮细胞并在其中发育繁殖从而引起痢疾病症的大肠杆菌,故也称痢疾样大肠杆菌。世界各地每年因腹泻死亡的婴幼儿病例报道中,EIEC起重要作用。近年日益引起对其研究的关注,但国内尚未见到公开报道。为了探讨EIEC在我省的流行情况,我们于1985年在西安市儿童医院采集门诊腹泻患儿粪便进行了EIEC的实验分离工作,经过分离培养,生化特性鉴定,血清学试验及豚鼠角膜试验等最后鉴定出两株EIEC(199、267)。在鉴定工作中需要注意下列问题:
Invasive Escherichia coli (Tnteroinvasive Escherichia Coli referred to as EIEC), is invasive with epithelial cells and in which breeding and development of dysentery caused by E. coli, also known as dysentery-like Escherichia coli. EIEC plays an important role in the reports of infants and young children who die from diarrhea every year in the world. In recent years, it has aroused more and more attention to its research, but it has not yet seen any public reports in China. In order to investigate the epidemic situation of EIEC in our province, we collected the excretion of children with diarrhea in clinic in Xi’an Children’s Hospital in 1985 and carried out the experimental separation of EIEC. After the final isolation, culture, biochemical characterization, serological test and guinea pig cornea test Two strains of EIEC were identified (199,267). In the identification of work need to pay attention to the following questions:
