Abstract

A retrospective case-control study with a small population group revealed that, among clinical signs, vomiting but not diarrhea was significantly associated with the presence of diffusely adhering Escherichia coli (DAEC) in children suffering from gastroenteritidis (P < 0.05). Of the children carrying DAEC strains, those who were F1845 DNA probe positive had a significantly longer hospital stay than those who were F1845 DNA probe negative. We believe that the heterogeneity of DAEC strains is responsible for the discrepant results concerning their involvement in disease and that only some of these strains are really pathogenic for children.

摘要

一项针对小群体的回顾性病例对照研究显示,在临床症状方面,患有肠胃炎的儿童中,呕吐而非腹泻与弥漫性黏附大肠杆菌(DAEC)的存在显著相关(P < 0.05)。在携带DAEC菌株的儿童中,F1845 DNA探针呈阳性的儿童住院时间明显长于F1845 DNA探针呈阴性的儿童。我们认为,DAEC菌株的异质性导致了它们在疾病中的参与情况存在差异,并且只有其中一些菌株对儿童具有真正的致病性。
