仔猪传染性胃肠炎是由冠状病毒所引起仔猪的一种高接触性消化道传染病。本病的特征为:呕吐、水样腹泻、脱水、死亡率高。1流行病学本病于1945年在美国首次发现,以后在世界各国发生和流行。本病的发生有明显的季节性,在冬季和初春多发,但1月份为发病高峰期。多以暴发性,地方性、周期性流行。本病感染各年龄的猪,但10日龄以内的猪发病率高,死亡率为100%,断奶仔猪,育肥猪和成年猪发病较轻。病猪和带毒猪是主要传染源。狗、猫、狐狸等均为宿主,而狗排出的病毒对猪也有感染性。感染母猪的乳汁也可排出病毒,并能感染哺乳仔猪。病猪和健猪直接接触,… 相似文献

仔猪红痢也叫梭菌性肠炎,或称传染性坏死性肠炎,是由C型魏氏梭菌的外毒素所引起的仔猪的一种肠毒血症。本病的特征为:出血性下痢,肠坏死。1流行病学特点本菌在自然界中广泛存在,在大多数养猪的国家均有本病发生。本病在母猪产仔季节多发。主要感染1～3龄的新生仔猪,1周龄以上的仔猪发病很少,但也有2～4周龄的仔猪和断奶猪发病的报道。病猪和带菌猪是主要的传染源。病原菌在部分母猪肠道中,随粪便排出体外,污染饲料、饮水,用具和周围环境等,初生仔猪接触被污染的母猪体表如乳头等,经口通过消化道而感染发病。本病发病快,病程短,死亡率高。发… 相似文献

<正> 仔猪腹泻是病因复杂的一种综合症.引起仔猪腹泻的因素有环境、生理、营养以及病毒、细菌和寄生虫等.但在仔猪生产过程,引起仔猪腹泻的因素主要是病毒和细菌.本文就病毒、细菌性仔猪腹泻简介如下,供参考.一、病毒引起的仔猪腹泻症在仔猪培育过程中,引起仔猪腹泻的病毒很多,但最常见的是猪传染性胃肠炎病毒、猪流行性腹泻病毒和轮状病毒.(一)猪传染性胃肠炎TGE 是猪的一种高度接触传染性的消化道疾病,以呕吐、严重腹泻和脱水为特征.本病自1946年美国首次报道以来,在世界各国均有发生.我国也流行本病,是一种危害猪较严重的传染病. 相似文献

正猪梭菌性肠炎是由C型产气荚膜梭菌(又称魏氏梭状芽孢杆菌)引起的1周龄以内猪最为多见的出血性腹泻,因此亦称之为仔猪红痢。其特征是排红色粪便,肠黏膜坏死,病程短,病死率高。在卫生条件差的猪场发病较多,危害较大。1流行病学本病的发生有明显的年龄特点,通常发生于出生后12h~7日龄的乳猪,1~3日龄最为多发,1周龄以上的仔猪很少发生,但也有2~4周龄仔猪发生本病的报道。在同一群猪 相似文献

仔猪传染性水疱病,简称水疱病,是由水疱病病毒所引起仔猪的一种急性传染病。本病的特征为:在蹄、口、鼻镜及乳头部位的皮肤和黏膜发生水疱烂斑。1流行病学特点本病于1964年在意大利首次作了报道,以后在香港、英格兰,欧洲和亚洲一些国家也先后发生了本病。本病一年四季均可发生,但以冬春季多发。在自然界病毒只感染猪,不感染其他动物。对人有一定的感染性。对不同品种、性别、年龄的猪均有易感性,但仔猪较成猪敏感。病猪和带毒猪是主要传染源。病猪的所有器官和组织均含有病毒。通过粪便,尿液,唾液、乳汁、水疱皮和水疱液排出病毒,污染圈舍环… 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
