Abstract

From November 2021 to January 2022, 20 growing-pig sites in central Iowa reported severe clinical respiratory disease and weekly mortality of up to 50%. Actinobacillus pleuropneumoniae serotype 15 was identified as the causative agent of the clinical disease. Given that A pleuropneumoniae serotype 15 has been infrequently diagnosed in the United States, an outbreak investigation was conducted to explore biosecurity hazards and epidemiological aspects associated with the surge of cases. The investigations revealed that all farms had significant gaps in biosecurity and relied heavily on third-party service providers, which may have contributed to the pathogen spread.

2021-2022 年冬季爱荷华州中部胸膜肺炎放线杆菌血清 15 型疫情调查

从 2021 年 11 月到 2022 年 1 月，爱荷华州中部的 20 个生猪饲养场报告了严重的临床呼吸道疾病，每周死亡率高达 50%。经鉴定，胸膜肺炎放线杆菌血清型 15 是临床疾病的致病菌。鉴于 15 型胸膜肺炎放线杆菌血清型在美国并不常见，因此对疫情进行了调查，以探究与病例激增相关的生物安全隐患和流行病学方面的问题。调查显示，所有农场在生物安全方面都存在重大漏洞，并严重依赖第三方服务提供商，这可能是导致病原体传播的原因之一。

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.
