摘要
棘球蚴病/包虫病(cystic echinococcosis,CE)是一种全球性的人畜共患动物源性疾病,严重威胁人类和家畜的生命.由细粒棘球蚴引起的CE在我国高发流行,免疫接种是预防该病流行的最理想途径,在过去的几十年中,许多研究已经描述了该病的保护性候选抗原及其在终末宿主和中间宿主免疫中的作用.目前EG95重组蛋白疫苗效果最好,对中间宿主羊的保护力可达到96％～100％.但终末宿主犬作为传播的核心传染源,对其仍缺乏有效的防控手段,尤其是缺乏有效的接种疫苗,因此疫苗在犬身上的潜在应用是未来研究的重点.能抑制犬体内虫体发育并减少虫体在犬肠道内产卵量的疫苗研发将有望控制包虫病在流行地区的传播,大大加快该病的控制和消除.本研究从细粒棘球绦虫的生命周期、分子流行病学、地理分布以及终末宿主犬疫苗候选抗原等方面进行系统综述,旨在对CE的传播、未来发展方向和防治提供理论参考,为加速我国在CE终末宿主疫苗的研发进程和尽早应用于防控实践奠定基础.
Abstract
Echinococcosis/hydatidosis is considered a cosmopolitan zoonosis and seriously threatens the lives of humans and animals.Cystic echinococcosis caused by Echinococcus granulosus is highly endemic in China and immunization is the most ideal way to prevent epidemics.In the last few dec-ades,many studies have been conducted on the protective candidate antigens of this disease and its role in the final and intermediate host.Currently,the Eg95 recombinant protein vaccine showed a high degree of protection in sheep and as an intermediate host(96％to 100％efficacy).There are still no effective prevention and control measures for echinococcosis in dog which is the definitive host and main source of infection.Therefore,the potential use of vaccines in dogs is the focus of fu-ture research,where the development of vaccines involving in the prevention of parasite develop-ment in dogs and reducing egg-laying rates will ultimately lead to control of echinococcosis in en-demic areas.This systematic review aims to address the life cycle,molecular epidemiology,geo-graphic distribution of echinococcosis as well as vaccine candidate antigens in the final host for es-tablishing prevention and control programs of echinococcosis/hydatidosis.
