野猪非洲猪瘟的防控及疫苗研发

非洲猪瘟是一种主要感染家猪和野猪的烈性传染病,2018年8月,我国发生第1起非洲猪瘟疫情,自此,非洲猪瘟在我国呈点状传播态势,给我国养猪业造成了巨大的经济损失。野猪作为非洲猪瘟的天然宿主,在非洲猪瘟的流行和传播中发挥着重要的作用。本文主要从野猪非洲猪瘟防控措施以及疫苗的研发等方面进行阐述,以期为我国非洲猪瘟防控提供借鉴。     

开春后规模猪场重点猪病的防控

<正>开春时节,天气乍暖还寒,腹泻仍是猪的常发病、多见病。要注意鉴别诊断,分清病因,对症下药,才能达到控制目的。1非洲猪瘟——防控形势十分严峻非洲猪瘟是由非洲猪瘟病毒引起的高度接触性传染病。病猪、康复猪和隐性感染猪为主要传染源。带毒钝缘软蜱也是传染源之一。主要通过接触或采食被非洲猪瘟病毒(ASFV)污染的物品经口传染;短距离可经空气传播;也可经钝缘软蜱叮咬传播。家猪、野猪易感。家猪高度易感,且无明显的品种、日龄和性别差异。欧亚野猪易感,但非洲野猪,特别是疣猪和薮猪虽感染     

欧盟国家减缓非洲猪瘟在猪群中传播的相关措施

非洲猪瘟在过去的几十年从高加索地区传播至东欧,严重影响了家猪和野猪的健康。为了减缓非洲猪瘟的传播速度,欧盟针对易感猪群建立了减缓传播的方法。目前对于非洲猪瘟没有有效的疫苗和治疗方法,所以防止非洲猪瘟的进入和传播只能依靠于严格的防控手段。
