畜禽疫病是危害畜牧业和畜产品安全的主要因素,事关人民群众的身体健康和生命安全,事关经济健康发展和社会稳定,事关畜牧业的持续健康发展.提高畜禽防疫和疫病控制水平,建立健全畜禽疫情测报、监控、检疫体系,有效防止现有畜禽疫病和境外恶性传染病入侵,维护畜牧业的生产安全,确保畜禽产品生安全,保持畜牧业的优势地位和健康发展势头,是当前迫切需要解决的问题. 相似文献

在动物的某些疾病发生前后有计划、有目的的正确投服兽用药物，可以防止畜禽疾病发生、发展，以及疾病的蔓延，还可以促进畜禽健康生长，提高畜禽产品的质量，增加生产效益，如使用不当，则可能造成不可估量的损失，因而应引起广大兽医诊疗工作者及养殖户的重视。 相似文献

近几年来，国际上严峻的畜禽疫病形势越来越清楚地证明，对畜禽疫病防制不力可以带来惨痛的灾难，甚至造成全球性的影响。这些疫病暴发和流行的后果是严重的，损失是巨大的，影响是广泛的，教训是深刻的，应当引起我们认真反思，引以为戒。在我国畜牧业不断发展、畜禽产品国际贸易日益活跃和我国即将加入世贸组织的今天，进一步加大畜禽疫病防制力度，防止畜禽疫病的发生和流行，无疑有着重大的现实意义。从我国的现实情况看，加强畜禽疫病防制既迫在眉睫又任重道远，至少应当在以下八个方面作出不懈的努力。１要提高认识 国内外畜禽疫病的… 相似文献

在精准扶贫政策的有力推动下，大力发展畜牧业，促进贫困户早日脱贫已成为当政府的首选项目。但是因畜禽发展必然加大种畜禽或生产群的需求，致使畜禽的横向、纵向流通加剧，导致畜禽疫病的输入概率增加，稍有不慎，就会引起一方的疫病流行和暴发，病死畜禽数量急剧增多，无害化处理难度加大，随地随处乱丢或不按要求掩埋病死畜禽事件时有发现，给畜禽疫病的传播造成可乘之机。因此如何有效处置病死畜禽，防止畜禽疫病传播，已成为当前畜牧业生产发展遇到的新难题。 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
