我国高致病性猪蓝耳病疫情目前得到有效控制,高致病性猪蓝耳病免疫措施在防控工作中发挥了关键作用。2006年夏季,我国南方省份发生了猪“高热病”疫情。经过专家综合分析和多次复核,确定该病毒是猪“高热病”的原发病因,定名为“高致病性猪蓝耳病”。2007年上半年,高致病性猪蓝耳病疫情继续呈点状散发,下半年随着高致病性猪蓝耳病疫苗的供应量逐步加大,生猪疫情得到有效遏制。7-8月在高致病性猪蓝耳病的高发期,生猪疫情发病率比6月份和去年同期明显下降。10月1日-25日,全国高致病性猪蓝耳病疫点29个,发病3608头、死亡710头。与9月相比,分别… 相似文献

据悉,北京市日前已完成全市158.4万头生猪的高致病性猪蓝耳病首次免疫工作,成为国内第一个完成高致病性猪蓝耳病免疫的省份,为防止疫情的传入和发生奠定了良好的基础。截至目前,北京没有发生一例高致病性猪蓝耳病疫情。[第一段] 相似文献

<正>自2007年全国暴发高致病性猪蓝耳病以来,高致病性猪蓝耳病在岚皋县也是年年发生,成为常见病、多发病,在局部地区还造成严重损失,应该引起各方面高度重视。高致病性猪蓝耳病俗称"蓝耳病",是由猪繁殖与呼吸综合征高毒力变异株引起的猪的一种急性、热性、高接触传染性、高致死率的烈性传染病。以高发病率、高烧、高死亡率为显著特点。1流行病学特征高致病性蓝耳病仅传染猪和野猪。该病没有明显季节性。病猪及其污染物、病猪肉是重 相似文献

高致病性猪蓝耳病是由猪蓝耳病(繁殖与呼吸综合征)病毒变异株引起的一种急性高致死性疫病。该病来势猛,传播快,病猪死亡率高。2006年夏秋之际,我国20多个省市发生了高致病性猪蓝耳病疫情,给养猪业造成了很大损失,生猪存栏的下降,引发猪肉价格的上涨,为此,对高致病性猪蓝耳病的研究及防治引起了国内外相关领域的广泛关注和高度重视。下面就高致病性猪蓝耳病的流行特点及防治做简要分析。 相似文献

我国的中南、华东地区自2006年夏季开始发生大范围猪高致病性蓝耳病,然后向全国范围延伸,猪高致病性蓝耳病的临床症状主要是呼吸急促、皮肤发红并且体温升高,解剖病猪可以发现病猪有内脏出血或者肺炎等症状。高致病性蓝耳病的发病率和死亡率都很高,并且很难治愈,给我国的养殖户造成了很大的经济损失。本文就猪的高致病性蓝耳病的诊断与防治展开探讨。 相似文献

养猪场如何制定科学合理的免疫方案 总被引:1,自引:1,他引:0
首先,要摸清本猪场及周边猪场的疫病史,有针对性地制定免疫方案。高致病性猪蓝耳病疫情,使得猪的疫情变得更为复杂。据研究证实,猪的高致病性蓝耳病病毒主要侵害猪的免疫系统,使机体抵抗力下降,同时抑制猪瘟抗体的水平。当发生高致病性蓝耳病时,多呈现混合感染,主要是附红细胞体、圆环病毒、猪链球菌、猪瘟病毒等与高致病性猪蓝耳病病毒一起混合感染发病。 相似文献

要闻高致病性猪蓝耳病防控形势严峻中国农业部副部长尹成杰6月13日指出,中国当前处于高致病性猪蓝耳病疫情高发期,大部分生猪没有进行免疫,加之病毒污染面较大,生猪大范围调运增大疫情传播可能性等因素,疫情防控形势严峻。而针对高致病性猪蓝耳病的专用新型疫苗已于今日正式投入使用,将在防控中发挥重要作用。据悉,2006年夏秋季节,中国南方部分地区发生猪病疫情,给养猪业造成较大经济损失。通过分析,专家锁定了新变异猪蓝耳病病毒为主要病原,并定名为“高致病性猪蓝耳病”。今年前5个月,中国有22个省份先后发生高致病性猪蓝耳病疫情。疫情县市194个、疫点289个,发病猪45858头,死亡18597 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
