猪伪狂犬病是一种以侵害中枢神经系统为主的病毒性传染病 ,主要造成哺乳仔猪大量死亡。( 1 5日龄以内仔猪死亡率为 1 0 0 % ) ,怀孕母猪发生流产、死胎、木乃伊、产弱仔等情况 ,对养猪业危害较大。1 发病情况自 2 0 0 1年 1月以来 ,我区有多处规模猪场和个体养猪户发生本病。如某规模猪场 1～ 1 2月份共产仔 45 3窝 ,有 40窝整窝死亡 ,共产仔 45 2 5头 ,其中产死胎 5 4 9头 ,占 1 2 1 3% ;产弱仔 1 0 1 1头 ,占 2 2 35 % ;成活 2 0 4 0头 ,死 2 4 85头 ,死亡率达5 4 92 %。其它养殖场 (户 )的发病情况都与此场类似 ,损失都比较严重。2 … 相似文献

1基本情况我县某猪场有母猪10头,公猪2头,2003年上半年有6头母猪先后怀孕,其中2头母猪怀孕2月左右先后流产,其余4头母猪中有一头提前分娩,产死胎2头,活仔9头,其中有2头出生后很快死亡,有2头推迟分娩,共产死胎5头,活仔15头,其中有5头出生后很快死亡;仅有1头按时分娩,产死胎1头,活仔12头,其中有3头出生后不久死亡。从6头母猪产仔情况分析,流产率达33%,死胎率达19%,弱仔率23.8%,严重降低该猪场种猪的生产能力,降低经济效益。经综合诊断,确诊为碘缺乏引起种猪繁殖能力下降,导致流产,产死胎、弱仔。该猪场立即采取措施,对种猪进行补碘,以后的母猪… 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
