肠出血性大肠埃希菌(EHEC)是一种食源性致病菌,对公众健康具有重要意义。EHEC定植于大肠,导致腹泻、出血性结肠炎,在某些情况下,由于志贺毒素(STX)的产生,还会导致危及生命的溶血性尿毒症综合征(HUS)。缺乏有效的临床治疗、感染后的后遗症和人类的死亡率支持了对预防方法的迫切需要,如疫苗的开发。牛是EHEC的主要宿主,被认为是主要的食品污染源,它的脱落促使了特许疫苗的开发,以减少EHEC在反刍动物中的定植。虽然小鼠模型不能完全概括人类感染情况,但它们通常被用来评估EHEC疫苗和在宿主中引起的免疫/保护反应。不同的EHEC接种对小鼠的敏感性不同;因此,表现出不同的死亡率和STX介导的肾脏损伤。因此,在这个模型中,已经采用了几种实验方案来开发EHEC特异性疫苗。最近评估的候选疫苗包括那些由毒力因子单独或作为融合亚单位、基于DNA的减毒细菌和细菌幽灵组成的疫苗。在这篇综述中,我们总结了肠出血性大肠杆菌疫苗的设计和测试方面的进展,以及在小鼠模型中使用不同的策略来评估新型肠出血性大肠杆菌疫苗。
Enterohemorrhagic Escherichia coli (EHEC) strains are food borne pathogens with importance in public health. EHEC colonizes the large intestine and causes diarrhea, hemorrhagic colitis and in some cases, life-threatening hemolytic-uremic syndrome (HUS) due to the production of Shiga toxins (Stx). The lack of effective clinical treatment, sequelae after infection and mortality rate in humans supports the urgent need of prophylactic approaches, such as development of vaccines. Shedding from cattle, the main EHEC reservoir and considered the principal food contamination source, has prompted the development of licensed vaccines that reduce EHEC colonization in ruminants. Although murine models do not fully recapitulate human infection, they are commonly used to evaluate EHEC vaccines and the immune/protective responses elicited in the host. Mice susceptibility differs depending of the EHEC inoculums; therefore, displaying different mortality rates and Stx-mediated renal damage. Therefore, several experimental protocols have being pursued in this model to develop EHEC-specific vaccines. Recent candidate vaccines evaluated include those composed of virulence factors alone or as fused-subunits, DNA-based, attenuated bacteria and bacterial ghosts. In this review, we summarize progress in the design and testing of EHEC vaccines and the use of different strategies for the evaluation of novel EHEC vaccines in the murine model.
