Abstract

Senecavirus A (SVA) has been demonstrated to be a causative agent for vesicular disease in swine. It is clinically indistinguishable from other agents that cause vesicular disease such as foot-and-mouth disease virus (FMDV), which is a reportable foreign animal disease (FAD). Thus, an investigation is initiated to rule out FMDV every time a vesicle is observed. Senecavirus A has now been reported across the Americas and Asia, and it appears the ecology of this virus has changed from sporadic infections to an endemic disease in some areas. In addition to vesicular disease, there have also been reports of increased neonatal mortality on affected sow farms. Knowledge about the pathogenesis of SVA in swine can provide many benefits to the swine industry. Understanding how long the virus can be detected in various sample types after infection can aide in choosing the correct samples to collect for diagnosis. In addition, the duration of virus shedding can help determine measures to control virus spread between animals. Prevention of SVA infection and disease with an efficacious vaccine could improve swine welfare, minimize SVA transmission, and reduce the burden of FAD investigations.

塞内卡病毒A:常见问题

塞内卡病毒A (SVA)已被证明是猪水疱病的病原体。它在临床上与引起水疱性疾病的其他病原体如口蹄疫病毒(FMDV)难以区分，口蹄疫是一种应报告的外来动物疾病(FAD)。因此，每次观察到囊泡时，都要进行调查以排除FMDV。目前已在美洲和亚洲报告了塞内卡病毒A，该病毒的生态似乎已从散发感染转变为某些地区的地方病。除了水疱病外，也有报道称受影响的母猪养殖场的新生儿死亡率增加。了解猪SVA的发病机制可以为养猪业提供许多好处。了解感染后在不同类型的样本中可以检测到病毒的时间可以帮助选择正确的样本进行诊断。此外，病毒脱落的持续时间可以帮助确定控制病毒在动物之间传播的措施。用有效的疫苗预防SVA感染和疾病可以改善猪的福利，减少SVA的传播，减轻FAD调查的负担。

期刊介绍： The Journal of Swine Health & Production (JSHAP) is an open-access and peer-reviewed journal published by the American Association of Swine Veterinarians (AASV) since 1993. The aim of the journal is the timely publication of peer-reviewed papers with a scope that encompasses the many domains of applied swine health and production, including the diagnosis, treatment, management, prevention and eradication of swine diseases, welfare & behavior, nutrition, public health, epidemiology, food safety, biosecurity, pharmaceuticals, antimicrobial use and resistance, reproduction, growth, systems flow, economics, and facility design. The journal provides a platform for researchers, veterinary practitioners, academics, and students to share their work with an international audience. The journal publishes information that contains an applied and practical focus and presents scientific information that is accessible to the busy veterinary practitioner as well as to the research and academic community. Hence, manuscripts with an applied focus are considered for publication, and the journal publishes original research, brief communications, case reports/series, literature reviews, commentaries, diagnostic notes, production tools, and practice tips. All manuscripts submitted to the Journal of Swine Health & Production are peer-reviewed.
