Abstract

Wild pigs (Sus scrofa) are among the most detrimental invasive species in the USA. They are damaging to crops and agriculture, pose a public health risk as reservoirs of zoonotic pathogens, and may also spread disease to livestock. One pathogen identified in wild pigs is bovine viral diarrhea virus (BVDV), a virus that causes an economically important disease of cattle (Bos taurus and Bos indicus). We sought to determine the BVDV seroprevalence in wild pigs in 17 states across the US and to determine whether age category, sex, or location were associated with a positive antibody titer. Serum samples from 945 wild pigs were collected from 17 US states. Virus neutralization assays were performed to determine antibody titers against BVDV-1b and BVDV-2a. Total BVDV seroprevalence for the study area was 5.8% (95% confidence interval [CI], 4.11-8.89). Seroprevalence across all evaluated states was determined to be 4.4% (95% CI, 2.48-6.82) for BVDV-1b and 3.6% (95% CI, 1.54-5.60) for BVDV-2a. The seroprevalence for individual states varied from 0% to 16.7%. There was no statistical difference in median antibody titer for BVDV-1b or BVDV-2a by sex or age category. State seroprevalences for both BVDV-1b and BVDV-2a were associated with wild pig population estimates for those states.

美国 17 个州野猪（Sus scrofa）中牛病毒性腹泻病毒的血清流行率。

野猪（Sus scrofa）是美国危害最大的入侵物种之一。它们对农作物和农业造成破坏，作为人畜共通病原体的贮藏地对公共健康构成威胁，还可能将疾病传播给牲畜。在野猪身上发现的一种病原体是牛病毒性腹泻病毒（BVDV），这种病毒会导致牛（金牛和阉牛）患上一种具有重要经济价值的疾病。我们试图确定美国 17 个州野猪的 BVDV 血清流行率，并确定年龄类别、性别或地点是否与抗体滴度呈阳性有关。我们从美国 17 个州收集了 945 头野猪的血清样本。进行病毒中和检测以确定 BVDV-1b 和 BVDV-2a 的抗体滴度。研究地区的 BVDV 血清总流行率为 5.8%（95% 置信区间 [CI]，4.11-8.89）。在所有接受评估的州中，BVDV-1b的血清流行率为4.4%（95% CI，2.48-6.82），BVDV-2a的血清流行率为3.6%（95% CI，1.54-5.60）。各州的血清流行率从0%到16.7%不等。不同性别或年龄组的BVDV-1b或BVDV-2a抗体滴度中位数没有统计学差异。各州的BVDV-1b和BVDV-2a血清流行率与这些州的野猪数量估计值有关。

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.
