猪伪狂犬病毒传入猪场的风险评估模型研究

摘要

In order to assess the introduction risk of pseudorabies rirus(PRV) into a PRV-negative pig farm in the next 3 years,risk pathway was established based on analysis of published papers,the national surveillance data,and suggestions from experts. Using this created pathway in combination with the data collected and sorted from the related various risk factors,qualitative risk assessment was conducted. The results showed that breeding pigs without detection forfield virus antibodies before introduction,outsourcing semen without detecting PRV,aerosol and mice carrying virus were the extremely high risk factors in the pathway of PRV introduction.%为评估未来3年内猪伪狂犬病毒（PRV）变异株传入某阴性种猪场的风险，通过文献分析，结合国家定点监测分析结果和专家经验，建立了PRV传入猪场的风险路径。以该风险路径为依据，采集和整理与风险路径中各风险因素相关的数据，开展了定性分析评估。结果发现，PRV通过未经野毒抗体检测的种猪、外购精液，以及气溶胶和带毒老鼠传入的风险极高。
