鸭传染性浆膜炎又名鸭疫里默氏杆菌病,是鸭的一种接触性传染病。本病呈急性或慢性经过,以纤维素性心包炎、肝周炎和气囊炎为特征。本病常引起小鸭大批死亡以及发育迟缓,造成很大经济损失,是危害养鸭业的最主要传染病之一。一般感染2周龄~4周龄雏鸭,1周龄以内的雏鸭很少发病[1]。2018年8月份,某鸭场6日龄樱桃谷肉鸭发病,死亡病鸭的病理变化表现为浆膜炎,经过药物治疗疫病得到控制。 相似文献

变形杆菌病在临床较为少见,在我县为首例,其发病急,死亡率较高。现将有关发病及诊治情况报道如下。1发病情况1996年10月间,容县容城镇财政所樱桃谷鸭原种场因从南宁某场引进鹦桃谷鸭雏苗1500羽,从第二到第七天发生死亡,呈直线上升,到第10天才稳定些,共死亡雏鸭690羽,死亡率46%,还感染该场自己孵化出来的雏鸭,死亡率少则20%,高则38.5%。发病初期,该场管理人员未引起足够重视,误认为是运输清维方法不当等因素引起,不请兽医诊治,只到兽医门诊咨询买了些药物治疗。因疗效不佳,方请笔者前往诊疗。2临床症状病鸭离群,羽毛松… 相似文献

北海市某鸭场今年8月3日、8月23日,分别从南宁、钦州引进樱桃谷鸭苗900和500只。这两批鸭都是放在同一栋鸭舍,同一饲养员饲养。9月22日下午,两群鸭都发病,到第二天中午,出现病状的30日龄的鸭有6只,50日龄的有16只(包括已死亡的4只)。临床症状及剖检:病鸭羽毛松乱,无光泽。两翅下垂,脚麻痹无力,走动困难,严重时,驱赶则见两翅扑地而走,走不到数步蹲伏于地上,有的两脚完全麻痹,伏地不 相似文献

<正>鸭传染性浆膜炎(原名鸭疫巴氏杆菌病),是由鸭疫巴氏杆菌引起的一种急性或慢性接触性传染病。主要侵害幼鸭,流行无明显的季节性,在发过病的鸭场会持续存在该病菌,引起不同批次的幼鸭感染发病。近年来,本病在养鸭场的危害日益突出,已成为影响养鸭业的一种主要传染病。为了更好地防治本病,提高养鸭户养殖效益,现将本人多年来诊治鸭传染性浆膜炎的经验介绍如下。 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

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
