Abstract

Vesicular stomatitis virus (VSV) outbreaks periodically occur in livestock in the western US and are thought to originate from outside this country. Feral swine (Sus scrofa) have been identified as an amplifying host for vesicular stomatitis New Jersey virus (VSNJV) and have been used to better understand the epidemiology of this virus through serosurveillance. This study aimed to determine if antibodies to vesicular stomatitis Indiana virus (VSIV) and VSNJV were present in feral swine in the western US and to determine if seropositive animals were associated with areas of previously detected VSV in livestock. A total of 4,541 feral swine samples was tested using virus neutralization (VN); samples exhibiting neutralizing activity against one or more of the viruses were confirmed using competitive ELISA (cELISA). Eight sera exhibited neutralizing activity by VN assay and a single serum sample from an animal from Kinney County, Texas sampled in December 2019 tested positive for antibodies to VSIV by cELISA. This finding is supported by a local outbreak of VSIV in horses in the same county in June 2019. The low prevalence of antibodies against VSNJV and VSIV was unexpected but indicates that feral swine in the western US do not represent an endemic reservoir for either of these viruses.

美国西部野猪（Sus scrofa）水泡性口炎病毒抗体监测，2013-21。

水泡性口炎病毒（VSV）会定期在美国西部的牲畜中爆发，并被认为来自美国境外。野猪（Sus scrofa）已被确定为新泽西州水泡性口炎病毒（VSNJV）的扩增宿主，并被用于通过血清监测更好地了解该病毒的流行病学。本研究旨在确定美国西部野猪体内是否存在印第安纳州水泡性口炎病毒（VSIV）和新泽西州水泡性口炎病毒（VSNJV）抗体，并确定血清阳性动物是否与之前在牲畜中检测到 VSV 的地区有关。共对 4541 份野猪样本进行了病毒中和 (VN) 测试；使用竞争性酶联免疫吸附法 (cELISA) 确认了对一种或多种病毒表现出中和活性的样本。通过 VN 检测，有 8 份血清表现出中和活性；通过 cELISA 检测，2019 年 12 月从德克萨斯州金尼县采样的一份动物血清样本的 VSIV 抗体呈阳性。2019 年 6 月在同一县的马匹中爆发的 VSIV 疫情也证实了这一发现。VSNJV和VSIV抗体的低流行率出乎意料，但这表明美国西部的野猪并不代表这两种病毒的流行库。

期刊介绍： The JWD publishes reports of wildlife disease investigations, research papers, brief research notes, case and epizootic reports, review articles, and book reviews. The JWD publishes the results of original research and observations dealing with all aspects of infectious, parasitic, toxic, nutritional, physiologic, developmental and neoplastic diseases, environmental contamination, and other factors impinging on the health and survival of free-living or occasionally captive populations of wild animals, including fish, amphibians, reptiles, birds, and mammals. Papers on zoonoses involving wildlife and on chemical immobilization of wild animals are also published. Manuscripts dealing with surveys and case reports may be published in the Journal provided that they contain significant new information or have significance for better understanding health and disease in wild populations. Authors are encouraged to address the wildlife management implications of their studies, where appropriate.
