Abstract

Senecavirus A (SVA) is a member of the Senecavirus genus within the Picornaviridae family. An SVA infection causes ulcerative lesions indistinguishable from other vesicular diseases. We describe the genetic characterization of the first SVA detected in Mexico on 2 swine farms. Phylogenetic analyses demonstrated a genetically close relationship with SVA isolates from the United States detected in 2017, sharing a 98.3% to 98.4% nucleotide identity. Neverthe- less, genetic differences were found. In Mexico, SVA is considered an exotic virus. Although the introduction source could not be determined, further studies are needed to understand the molecular epidemiology of SVA detected in Mexico.

墨西哥猪中塞内卡病毒A的首次检测和遗传特征分析

塞内卡病毒A (SVA)是小核糖核酸病毒科塞内卡病毒属的一个成员。SVA感染引起溃疡性病变，与其他水疱性疾病难以区分。我们描述了在墨西哥2个养猪场检测到的第一个SVA的遗传特征。系统发育分析表明，该菌株与2017年从美国检测到的SVA分离株具有密切的遗传关系，核苷酸同源性为98.3%至98.4%。尽管如此，遗传差异还是被发现了。在墨西哥，SVA被认为是外来病毒。虽然无法确定引入源，但需要进一步研究了解墨西哥检测到的SVA的分子流行病学。

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.
