In Corsica, extensive pig breeding systems allow frequent interactions between wild boars and domestic pigs, which are suspected to act as reservoirs of several zoonotic diseases including hepatitis E virus (HEV). In this context, 370 sera and 166 liver samples were collected from phenotypically characterized as pure or hybrid wild boars, between 2009 and 2012. In addition, serum and liver from 208 domestic pigs belonging to 30 farms were collected at the abattoir during the end of 2013. Anti-HEV antibodies were detected in 26% (21%-31.6%) of the pure wild boar, 43.5% (31%-56.7%) of hybrid wild boar and 88% (82.6%-91.9%) of the domestic pig sera. In addition, HEV RNA was detected in five wild boars, three hybrid wild boars and two domestic pig livers tested. Our findings provide evidence that both domestic pig and wild boar (pure and hybrid) act as reservoirs of HEV in Corsica, representing an important zoonotic risk for Corsican hunters and farmers but also for the large population of consumers of raw pig liver specialties produced in Corsica. In addition, hybrid wild boars seem to play an important ecological role in the dissemination of HEV between domestic pig and wild boar populations, unnoticed to date, that deserves further investigation.
在科西嘉岛,广泛的养猪系统使得野猪与家猪之间频繁互动,而家猪被怀疑是包括戊型肝炎病毒(HEV)在内的几种人畜共患病的宿主。在此背景下,于2009年至2012年间从表型特征明确为纯种或杂种野猪身上采集了370份血清和166份肝脏样本。此外,在2013年末,从30个农场的208头家猪身上在屠宰场采集了血清和肝脏。在纯种野猪血清中,26%(21%-31.6%)检测到抗HEV抗体;杂种野猪血清中,43.5%(31%-56.7%)检测到抗HEV抗体;家猪血清中,88%(82.6%-91.9%)检测到抗HEV抗体。此外,在所检测的5头野猪、3头杂种野猪和2头家猪的肝脏中检测到了HEV RNA。我们的研究结果表明,家猪和野猪(纯种和杂种)在科西嘉岛都是HEV的宿主,这对科西嘉岛的猎人、农民以及大量食用科西嘉岛生产的生猪肝特色产品的消费者来说,是一个重要的人畜共患病风险。此外,杂种野猪似乎在HEV在家猪和野猪种群之间的传播中发挥着重要的生态作用,这一作用迄今未被注意到,值得进一步研究。
