摘要

2500头以前没有接种肺炎支原体疫苗的母猪群被感染。猪肺炎分枝杆菌和甲型H1N1pdm09流感病毒均在有临床症状的母猪中被发现。在大约10%的母猪中观察到持续2至4天的咳嗽，在爆发期间有26头母猪死亡。对业绩指标没有明显影响。聚合酶链反应和血清学结果显示猪群中肺炎支原体进展迅速，感染可能在几周内发生。迅速实施了一项消除计划，以便恢复销售阴性动物。

Infection of a naïve sow herd with Mycoplasma hyopneumoniae

A 2500-sow herd previously free of, and unvaccinated for, Mycoplasma hyopneumoniae became infected. Both M hyopneumoniae and influenza A H1N1pdm09 virus were identified in sows showing clinical signs. Coughing lasting 2 to 4 days was observed in approximately 10% of sows and 26 sows died over the course of the outbreak. There was no apparent impact on performance indicators. Polymerase chain reaction and serological results showed that M hyopneumoniae progression within the herd was fast and that infection may have occurred within a few weeks. An elimination program was quickly implemented so that sale of negative animals could resume.

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.
