艾伯特埃希菌病原学与流行病学研究进展

Progress in microbiological and epidemiological characteristics of Escherichia albertii

艾伯特埃希菌(Escherichia albertii)是一种新发人兽共患病病原体,可引起以感染性腹泻为主的胃肠道疾病。自发现和命名以来,艾伯特埃希菌已造成多起食源性胃肠炎暴发,并广泛存在于多种禽类、野生动物中。由于目前常规的鉴定系统不能有效鉴定艾伯特埃希菌,该菌在全球的流行情况可能被严重低估。禽类等是艾伯特埃希菌的重要储存宿主,但其在疾病传播中的作用尚不清楚。本文对艾伯特埃希菌的生理生化特性、基因组特征、分离检测方法,以及艾伯特埃希菌在宿主动物、食品媒介及人群中流行情况的研究进展进行了综述,并对艾伯特埃希菌的感染风险及进一步的研究重点进行了展望。

Escherichia albertii is an emerging zoonotic enteropathogen which mainly causes infectious diarrhea.Since the discovery and naming of Escherichia albertii,it was found to be responsible for several outbreaks of foodborne gastroenteritis and widely distributed in avian and wild animals.Due to the lack of specific identification system,the global Escherichia albertii infections might be underestimated.Though avian has been considered as the important reservoir of Escherichia albertii,its role in disease transmission remains unclear.This study reviewed the biochemical properties,genomic characteristics,isolation and identification methods of Escherichia albertii,and its prevalence in human,host animals and food.The risk of Escherichia albertii infection and future perspectives in this field were also discussed.
