鸡球虫病是一种常见的急性流行性原虫病.鸡坏死性肠炎是由魏氏梭杆菌引起的以肠黏膜坏死脱落为特征的一种疾病.两病混合感染往往导致肉鸡生长发育缓慢并出现部分死亡,对养鸡业,尤其是肉鸡生产危害极大,该类病例多见于炎热多雨的季节.2008年夏季,山东枣庄地区因降雨频繁,气温高、湿度大,该类病发生较多.现以一养殖户饲养的1200只肉杂鸡混合感染为例,从发病情况、临床症状、剖检变化、实验室检查及治疗情况等方面简述如下. 相似文献

以中国知网作为数据统计源,检索鸡传染性支气管病毒混合感染案例,对混感临床案例的地区分布、发病鸡品种和鸡传染性支气管炎病毒混合感染疾病类型进行分析。结果表明,鸡传染性支气管病毒混合感染的地区分布与我国家禽存栏量的地区分布现状相符;肉鸡发生鸡传染性支气管病毒混合感染的比例远高于蛋鸡;细菌和病毒是鸡传染性支气管病毒混合感染的主要病原,支原体和寄生虫在混合感染中的占比很少;在细菌的混合感染中,大肠杆菌占绝对数量优势;在病毒中主要是新城疫病毒,其次是禽流感病毒,此外鸡传染性支气管病毒与新城疫病毒和禽流感病毒易发生三重感染。本文归纳了近10年我国鸡传染性支气管病毒混合感染的基本特征,为认清鸡传染性支气管防控存在的问题及提高疫病防控水平提供了有力参考。 相似文献

山东省白羽肉鸡中MDV、REV、CAV和ARV感染状况的病原学调查 总被引:2,自引:0,他引:2
为了解鸡马立克氏病病毒(MDV)、鸡传染性贫血病毒(CAV)、禽网状内皮增生病病毒(REV)和禽呼肠孤病毒(ARV)在山东省白羽肉用型鸡中的流行情况,试验采用地高辛标记的核酸探针-斑点杂交法对淘汰的商品肉鸡、病死商品肉鸡及淘汰肉种鸡进行了上述4种病毒病原的检测。结果表明:ARV主要以单一形式感染,在病死商品肉鸡中感染率最高(30.07%),在3种类型鸡中ARV感染率高于MDV,REV,CAV。MDV在淘汰肉种鸡中感染率(12.82%)高于其他2种鸡群,而REV,CAV,ARV感染率在病死商品肉鸡中最高。混合感染亦相当普遍,以淘汰肉种鸡最高(混合感染率达10.25%),高于任一病毒单独感染率,其次为病死商品肉鸡。 相似文献

肉鸡败血霉形体与大肠杆菌混合感染是当前商品肉鸡生产中最普遍的疾病之一.鸡败血霉形体与大肠杆菌混合感染可发生于各个季节,但在寒冷的月份,发病更剧烈,病程更长.发病日龄多集中在10~30日龄的雏鸡.鸡群在应激因素的作用下(特别是接种新城疫疫苗)易发病,首先出现呼吸道症状,4~5日后就会发现个别鸡只精神萎顿、消瘦、死亡,且日渐增多.特别是近年来,此病显得更加突出,严重影响着肉鸡业的发展.现就一病例诊治情况报告如下. 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
