摘要

本研究旨在确定四年来从伊朗儿童医院收集的粪大肠杆菌菌株的特征。我们对 67 株粪肠球菌分离株进行了毒力基因检测、变数串联重复（VNTR）和多病灶变数串联重复分析（MLVA）分型。高频率的毒力基因属于明胶酶（73%）和粪肠球菌（62%）。67 个粪肠球菌分离物的 MLVA 发现了 52 种 VNTR 模式和 38 种 MLVA 类型（MT）。此外，在儿童医院的不同病房还发现了遗传多样性，其中 MT1 是主要的 MT。

Molecular Analysis of Enterococcus Faecalis Isolates in a 4-year Period.

In the present research, we aimed to determine the characteristics of E. faecalis strains collected from an Iranian Children's Hospital for four years. Sixty-seven E. faecalis isolates with virulence genes detection, variable-number tandem repeat (VNTR), and multiple-locus variable-number tandem repeat analysis (MLVA) typing were investigated. A high frequency of virulence genes belonged to gelatinase (73%) and Enterococcus faecalis (62%). The MLVA of 67 E. faecalis isolates revealed 52 VNTR patterns and 38 MLVA types (MTs). Furthermore, genetic diversities with the majority of the MT1 as a major MT in different Wards of the Children's Hospital were found.
