规模猪场猪伪狂犬病的净化研究

猪伪狂犬病是由伪狂犬病病毒引起的多种动物共患传染病,可引起仔猪大量发病死亡,母猪流产、死胎等繁殖障碍,育肥猪生长发育缓慢,经济损失惨重。为净化规模猪场的猪伪狂犬病,试验采用综合性的净化措施,除淘汰病猪及临床症状猪、加强饲养管理等技术措施外,采用猪伪狂犬病弱毒疫苗加强免疫,结合野毒抗体监测,成功的根除了伪狂犬的感染。

我国猪伪狂犬病的最新流行动态与防控措施

1伪狂犬病最新流行动态伪狂犬病病毒(PRV)是一个不可忽视的致病因子,造成伪狂犬病(PR)在全国大范围的传播流行,伪狂犬病病毒起到了推波助澜的作用,而且使猪病的感染流行复杂化。近年来一些猪场猪伪狂犬病免疫失败,猪伪狂犬病与其他疫病的混合感染不断涌现,使猪伪狂犬病的防控形势面临新的挑战。伪狂犬病并没有消失,而     

猪伪狂犬病防控与净化

伪狂犬病（Aujeszky’s Disease）是由伪狂犬病毒（Pseudorabies virus PRV）引起的多种家畜和野生动物以发热,奇痒（猪除外）及脑脊髓炎为主要特征的一种重要传染病;猪是伪狂犬病毒的自然宿主,可造成种猪繁殖障碍、仔猪早期大量死亡、商品猪生长迟滞,给畜牧业带来巨大损失。本病曾在全世界流行,中国自1947首次报道以来,目前已扩大到全国各地,隐性感染、临床发病及混合感染日趋严重,每年因为该病造成巨大的经济损失。世界上主要的养猪国家都已开始实施猪伪狂犬病的控制和净化项目,并在一些国家取得成功;借鉴国外成功的经验,根据我国猪伪狂犬病的流行状况及研究进展,并提出我们国家伪狂犬病防控策略和净化方案。     

我国种猪场进行伪狂犬病的净化势在必行

猪伪狂犬病是由伪狂犬病病毒引起猪的一种病毒性疾病，是我国规模化猪场的主要疫病。猪伪狂犬病的危害主要表现在母猪的繁殖障碍、仔猪的高死亡率和呼吸道疾病，是目前我国规模化猪场繁殖障碍和呼吸道疾病的主要病因之一。     

当前猪伪狂犬病的流行状况及防控对策

过去在我国猪群中很少发现伪狂犬病野毒的存在,但自从2011年以来,华东、华中及华北等地的猪场出现猪伪狂犬病较频繁.2012年山东、湖北、河南等地区猪场严重暴发伪狂犬病野毒,虽然患病猪群之前均接种过伪狂犬病疫苗,猪场损失巨大.本文现对当前猪伪狂犬病的流行状况及防控对策进行了探讨分析,对猪伪狂犬病的研究具有十分重要的意义.     

猪伪狂犬病病原、疫苗的研究现状及防制思路

伪狂犬病(Pseudorabies.PR)是由伪狂犬病病毒(PRV)引起的猪、牛、羊等多种家畜及野生动物的一种主要的急性传染病。病原属疱疹病毒科A亚科猪疱疹病毒。伪狂犬病(简称PR)是典型的自然疫源性疫病。其宿主广泛,猪是该病的主要宿主和传染来源。他引起妊娠母猪发生流产、死胎、木乃伊胎和新生仔猪大批死亡,耐过的猪也成为僵猪,是引起猪繁殖障碍的主要疫病之一。

黑龙江省种猪场猪伪狂犬病的监测与防制

猪伪狂犬病(PR)是由疱疹病毒科、猪疱疹病毒Ⅰ型引起的多种畜禽及野生动物发生的急性传染病[1].一些发达国家通过监测与净化措施已控制或消灭该病.我国作为世界上最大的养猪国,也是世界上伪狂犬病危害最大的国家之一.因此需要建立一套切实可行的监测与净化技术,控制并逐步消灭伪狂犬病.为控制我省猪伪狂犬病,在<种猪场疫病监测和净化技术研究>项目中开展种猪场猪伪狂犬病监测与净化技术比较试验.

Disease and destiny-mystery and mastery

When early people made their appearance, zoonotic infectious diseases were already waiting, but epidemic diseases did not appear in human history until people began to live in large numbers under conditions of close contact, mainly during the last 10,000 years. Disease has decimated urban populations, conquered armies, and disrupted society. The focus here is on (1) the plague of Athens and the Black Death; (2) smallpox, influenza, and rabies; (3) avian influenza prion diseases, and foot & mouth disease; and (4) emerging and re-emerging diseases. All have veterinary public health associations. In Athens, Greece, in 430 BC, when the Spartans ravaged the countryside, hordes crowded into Athens so that orderly movements, space in which to live, and adequate supplies of food became impossible. Crowding of any population fosters disease transmission; chaos and disorder enhance it all the more. Out of northern Egypt came a terrible plague from across the Mediterranean Sea. The identity of the plague of Athens remains unsure, but the well-considered conclusion is Rift Valley Fever, a mosquito borne, viral zoonosis. The Black Death, also called the Plague, raged in Asia for centuries. In 1347, the Black Death was brought by a ship out of Asia to Sicily. The scenes of devastation were repeated throughout Europe, with 90% or more of the people dying in city after city. Influenza, too, has been a cause of periodic human epidemics, but the great pandemic of influenza occurred in the last months of World War I. In the years of highest occurrence, more than half the world's population became clinically infected. If veterinary public health had been born earlier, it could have led to elucidating the epidemiology of influenza and the plagues of Athens, Europe, and Asia. In turn, smallpox had also caused continual tragedy. In 1796, Edward Jenner began to harvest pustules of cowpox from children or infected cows and inject them into susceptible children. In 1980, the World Health Organization declared that smallpox had been eliminated from the world. Rabies, though, still strikes terror. A number of animal diseases, broadly termed emerging and re-emerging diseases, need surveillance because they have the potential to impact human health. From late in 2003 to 2007, the highly pathogenic H5N1 influenza virus in poultry infected at least 121 people and caused 62 deaths in four countries. The prion diseases, too, all have very high numbers in concentrated contacts. To control these diseases, veterinary public health is essential, with diagnosis, epidemiological surveillance, clinical manifestations, and prevention as primary measures.     

Foot and mouth disease and bluetongue: differences and similarities

On 26th of july 2007 a new case of bluetongue was notified in the Netherlands and on 2nd of august 2007 foot-and-mouth disease was diagnosed in Surrey, England, which raised the threat of having both infections simultaniously in one area. Bluetongue and foot-and-mouth disease have a different pathogenesis, but symptoms may resemble each other at a later stage of infection. The pathogenesis and possible clinical symptoms of both infections are discussed and illustrated with pictures.
