我国猪萎缩性鼻炎流行现状调查

摘要
为了解我国猪萎缩性鼻炎的流行现状,采用鼻甲骨病变评分方法对我国12个省市24个规模化养殖场的上市猪及死淘猪的鼻甲骨病变状况进行诊断评估。数据显示:100%的猪场感染萎缩性鼻炎,97.81%的样品出现鼻甲骨病变情况。结果表明,猪萎缩性鼻炎在我国广泛流行,且北方及东部地区感染情况更为严重,急需加强防控。
In order to investigate the prevalence of swine atrophic rhinitis in China, slaught and dead pigs were randomly collected from 24 industrialized pig farms of 12 provinces, these noses were dissected to score lesions in turbinate and nasal septum.The data showed that: 100% of farms were infected with atrophic rhinitis, and97.81% of the samples showed nasal lesions. The results showed that the swine atrophic rhinitis was widely prevalent in China, and the infection was more serious in the northern and eastern regions, so it is urgent to strengthen prevention and control.
