摘要: 禽致病性大肠杆菌(avian pathogenic Escherichia coli,APEC)是导致不同日龄禽类局部和全身感染的重要病原菌,也是人肠外致病性大肠杆菌(extraintestinal pathogenic Escherichia coli,ExPEC)毒力基因的重要储存宿主或来源。为深入理解APEC的感染过程、致病机理、宿主免疫应答及遗传抵抗机制、评估药物和疫苗防治效果,研究者通过不同途径建立了多种评估APEC毒力的实验感染模型。根据所涉及的系统不同可分为呼吸系统、脉管系统、肌肉系统、皮肤系统、生殖系统、消化系统及鸡胚系统等。此外,尚有小鼠与大鼠感染试验及组织培养细胞和外植块感染试验等。作者重点介绍了不同APEC实验感染模型的建立、致病机制、宿主应答及应用。

Abstract: Avian pathogenic Escherichia coli(APEC) is an important pathogen that causes localized and systemic infection in avian species of all ages.It is also an important reservoir or source of virulence genes of human extraintestinal pathogenic Escherichia coli (ExPEC).In order to understand deeply the infection progresses,pathogenesis,host immune responses and genetic resistance mechanism of APEC,and evaluate the efficacy of drugs and vaccines,several experimental infection models were established to evaluate the virulence of APEC through different approaches.According to the different systems involved,it can be divided into respiratory system,vascular system,musculoskeletal system,dermatological system,reproductive system,gastrointestinal system and chicken embryo system.In addition,there are infection experiments in mice and rats,tissue culture cells and explants infection experiments in vitro.The author highlights the establishment,pathogenesis,host responses and application of the different APEC experimental infection models.

Key words: avian pathogenic Escherichia coli(APEC); avian; chicken embryoes; mouse; rat; infection model
