牛的滴虫病为分布极其广泛的生殖道疾病,其主要特征是引起早期胚胎死亡,偶尔引起屡配不孕和子宫积脓。下文介绍该病的发病机理、诊断、治疗与防制措施。1发病机理滴虫病的病原为胎毛滴虫,其大小为10~15微米×5~10微米,多为椭圆形,前端有3根鞭毛,长度与虫体几乎相等。有些虫体耐低温,可存在于冷冻精  相似文献

牛胎毛滴虫感染牛生殖泌尿道,引起生殖道滴虫病或牛滴虫性流产。本病遍布世界各地。据报道:美国肉牛感染率为6—7%,德国南部和瑞士的一些地区奶牛感染率达30%。本病也曾是我国奶牛流产的基本原因之一。六十年代以来,我国已逐步推广人工  相似文献

引起奶牛繁殖障碍的因素很多,有先天性的,也有后天性的,而感染外源性疾病是后天性繁殖障碍中最常见的因素。除了常见的产科疾病以外,引起奶牛繁殖障碍的疾病还包括牛布鲁菌病、牛沙门氏菌病、牛传染性鼻气管炎、牛胎毛滴虫病、牛新孢子虫病、牛病毒性腹泻(牛黏膜病)等。在奶牛生产中,要根据实际发病情况,查明发生原因,采取相应措施,科学处置和防控。  相似文献

<正>牛毛滴虫病是一种牛寄生虫病,由寄生于牛生殖系统的胎毛滴虫通过交配传播,在乳牛群中引起生殖系统炎症、不孕和早期流产,给养牛业带来巨大经济损失。所以饲养者应该加以重视。1患病表现1.1低育牛群中一旦出现胎儿毛滴虫病的流行和传播,患牛的生育能力明显降低,随病情发展会出现返情、产犊间  相似文献

牛胎毛滴虫病主要危害牛的生殖系统,母牛感染后表现发情不规律、流产和死胎,公牛感染后阴茎局部出现结节和丘疹;该病主要经交配途径传播,虫体主要集中在阴道、子宫腔、包皮腔等处以及生殖道分泌物和精液中;预防该病需做好牛局部清洁工作,提升牛场的管理水平,同时加强对环境病原的防控;对于病牛的治疗推荐采用全身用药与局部冲洗相结合的方法,甲硝唑可通过口服或注射方式进行全身抗虫治疗,局部治疗可使用稀碘、乳酸依沙吖啶、高锰酸钾或苯扎溴铵等溶液对生殖部位进行冲洗。  相似文献

本場首次發現牛胎毛滴蟲是在1954年10月;第二次證實牛胎毛滴蟲是在1955年7月,由上海市第一醫學院葉英教授分離培養,其培養結果,另有專文報導。自1954年起,本場即展開了治療及預防牛胎毛滴蟲病的工作,收到效果。在1955年7月~1956年年底期間,本場未再發現牛胎毛滴蟲。茲將本場防治的初步經驗,報導如下: 一牛胎毛滴蟲病流行情况 1.發病率 1954  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
