Background data for: Grisefine lunger field trial

The dataset stems from a field trial of 14 Norwegian pig herds, in a case/control study of respiratory disease outbreaks. In seven herds with reported outbreaks of acute respiratory disease, data on clinical signs was recorded and samples for laboratory examination were collected. Diagnostic protocols were compared by parallel analysis of clinically healthy pigs from seven non-outbreak herds. Data was collected through diagnostic sampling of pigs, including serum samples, oral fluid samples and bacteriology following autopsy of respiratory organs. Epidemiological data was collected through farmer interviews and on farm registration. Data regarding biosecurity on farm was collected by the use of a standardized protocol for biosecurity scoring, the biocheck.Ugent. Additionally, production data and disease registration at slaughter has been collected through slaughterhouse reports from the individual farms.

本数据集源自一项针对14个挪威猪群的现场试验，属于呼吸道疾病暴发的病例对照研究（case/control study）。在7个报告过急性呼吸道疾病暴发的猪群中，研究人员记录了临床症状相关数据，并采集了实验室检测所需样本。通过对7个未暴发疫情的猪群中的临床健康猪只开展平行分析，完成了不同诊断方案的对比。数据通过猪只诊断性采样获取，涵盖血清样本、口腔液样本，以及呼吸器官剖检后的细菌学检验样本。流行病学数据经由养殖户访谈与猪场登记记录采集。猪场生物安全相关数据借助标准化生物安全评分方案biocheck.Ugent完成收集。此外，各猪场的屠宰场报告还提供了生产数据与屠宰阶段的疾病登记信息。
