摘要

猪甲型流感病毒(IAV-S)在宿主体内存活时间很短，其在宿主外的存活似乎不会成为消除尝试的重大障碍。猪场内的病毒传播似乎主要与哺乳仔猪和最近引进的后备母猪有关。将IAV-S引入母猪群的三种重要途径是受感染的猪、受感染的人和气溶胶。在母猪群中消除IAV-S病毒应该比消除猪繁殖与呼吸综合征病毒更容易，并且有可能在长期基础上保持IAV-S阴性。

Survival and transmission of swine influenza A virus within and between farms

Influenza A virus in swine (IAV-S) survives for a short period within the host, and its survival outside the host does not seem to be a significant obstacle to elimination attempts. Virus circulation within sow farms appears to be related mainly to suckling piglets and recently introduced gilts. Three important ways IAV-S is introduced into sow herds are infected pigs, infected humans, and aerosol. Elimination of IAV-S virus in sow herds should be easier than for porcine reproductive and respiratory syndrome virus, and it is possible to remain negative for IAV-S on a long-term basis.

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.
