戊型肝炎病毒(HEV)是戊型肝炎的病原体,是一种尚未得到充分研究的重要病原体。HEV通常引起自限性急性病毒性肝炎,然而,伴有神经系统和其他肝外表现的慢性感染已日益成为重要的临床问题。从猪身上发现猪戊型肝炎病毒并证明其人畜共患的潜力,导致从十多种其他动物物种中鉴定出非常多样化的戊型肝炎病毒株。来自猪、兔、鹿、骆驼和大鼠的HEV毒株已被证明可以跨越物种障碍并感染人类。已报告通过食用生的或未煮熟的动物肉类或直接接触受感染动物而发生人畜共患的戊型肝炎病毒感染。大量动物HEV变异的发现确实为开发有用的HEV动物模型提供了机会。在这篇综述中,我们讨论了HEV宿主范围、跨物种传播和人畜共患传播的最新进展。
Hepatitis E virus (HEV), the causative agent of hepatitis E, is an understudied but important pathogen. HEV typically causes self-limiting acute viral hepatitis, however chronic infection with neurological and other extrahepatic manifestations has increasingly become a significant clinical problem. The discovery of swine HEV from pigs and demonstration of its zoonotic potential led to the genetic identification of very diverse HEV strains from more than a dozen other animal species. HEV strains from pig, rabbit, deer, camel, and rat have been shown to cross species barriers and infect humans. Zoonotic HEV infections through consumption of raw or undercooked animal meat or direct contact with infected animals have been reported. The discovery of a large number of animal HEV variants does provide an opportunity to develop useful animal models for HEV. In this mini-review, we discuss recent advances in HEV host range, and cross-species and zoonotic transmission.
