<正>小反刍兽疫为高度接触性外来动物疫病之一,其病毒的致病率高,具有高死亡率特征,所以国际动物卫生组织规定小反刍兽疫为必须上报疫病。首次在我国发现小反刍兽疫疫情是在2007年7月西藏地区,在2013年11月新疆的几个市县也发现了该疫情,相继在2014年宁夏也发生了此疫情。由此可见,小反刍兽疫疫情逐步向国内蔓延,对畜牧业安全生产造成严重危害。因此,有效的实验室诊断方法在小反刍兽 相似文献

小反刍兽疫病毒引起的小反刍兽疫是一种主要发生于山羊、绵羊及一些野生小反刍兽的类似牛瘟症状的烈性接触性A类传染病.本病自1942年在象牙海岸首次记述以来,先后给非洲、中东等地区的小反刍动物养殖业带来严重灾害.到2006年初,我国周边孟加拉国、尼泊尔、印度、巴基斯坦等先后暴发疫情,近几年呈现蔓延趋势.2007年7月我国首例小反刍兽疫疫情在西藏发生,至今该病已严重威胁到我国小反刍兽的健康.本文结合当地养殖情况,对羊小反刍兽疫的临床诊断进行简要阐述. 相似文献

<正>2007年,西藏阿里的革吉、日土的山羊和绵羊群中发生小反刍兽疫,疫情得到迅速控制和扑灭。近期,多省(区、市)发生小反刍兽疫疫情,疫情呈暴发流行势态。小反刍兽疫是由副粘病毒科麻疹病毒属小反刍兽疫病毒引起的一种急性接触性传染病,世界动物卫生组织(OIE)将其列为A类动物疫病,在我国列为一类动物疫病。自2013年12月至今,我国有21省(区、市)发生小反刍兽疫疫情,共确诊146起,累计7 471只羊发病,死亡3 824 相似文献

小反刍兽疫(Peste des petits ruminants,PPR)是由副黏病毒科麻疹病毒属的小反刍兽疫病毒(Peste des petits ruminants virus, PPRV)引起的包括一些野生动物在内的小反刍动物的一种急性、烈性、致死性、高度接触性传染病,是严重危害畜牧业生产安全的重大跨国动物疫病之一。近年来,全球PPR疫情复杂,我国周边多个国家呈地方性流行态势。我国近期也陆续在多个省份发现疑似和确诊疫情。2014年3月27日,农业部宣布针对小反刍兽疫疫情启动一级响应。加强小反刍兽疫诊断工作、加快新型诊断试剂研发工作是当下做好防控小反刍兽疫的必要前提和必然要求,本文介绍了几种小反刍兽疫诊断方法的研究进展,为该病的诊断和有效防控提供理论依据。 相似文献

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. 相似文献

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. 相似文献

近几年,世界饲用添加剂市场增长较快,预计今后将进一步增长,据世界粮农组织(FAO)首领会议的倡议,到2015年,将使世界营养不良的人口削减一半,其间,肉制品将会以每年2%的速度增长,特别是加快猪肉和禽肉增长。这将促进世界添加剂,尤其是蛋氨酸和赖氨酸需求量的增加。 相似文献
