苏州地区某鸡场一例大肠杆菌病的诊治

鸡大肠杆菌病是由大肠杆菌引起的一种常见多发病。其中包括大肠杆菌性腹膜炎、输卵管炎、脐炎、滑膜炎、气囊炎、肉芽肿、眼炎等多种类型,该病对养鸡业危害较大。笔者对苏州地区一集约化鸡场发生的一例大肠杆菌病进行了细菌分离、鉴定,通过药敏实验确定其敏感的药物,分析发病原因,为鸡场以后的大肠杆菌病的防治提供资料。一发病情况苏州某鸡场饲养8000只2周龄褐壳蛋鸡。2004年4月6日,该鸡场发现有部分鸡只精神不振,当天死亡13只。4月7日又有一些鸡开始发病,死亡64只。8日、9日陆续死亡100多只,经诊断、治疗后,11日疫情得到控制。这次发病共…

农家养羊防缺硒

法氏囊病是由病毒引起的主要危害幼龄鸡的一种急性、高度接触性传染病。该病是一种免疫抑制病,雏鸡患病后因体液免疫中枢———法氏囊受损,使得鸡体对各种传染病如新城疫、马立克氏病、大肠杆菌病等病的易感性增加,同时降低鸡体的免疫应答能力,影响了免疫效果。1病例1.1发病情况2003年4月我市东郊乡某鸡场引进3000只海兰白雏鸡,至22日龄时,发现部分鸡只精神沉郁、打盹、羽毛松乱、不愿走动、减食、饮水量增加、拉黄白色水样粪便,个别鸡有啄肛现象。随后鸡只死亡数量开始迅速上升。到25日龄达死亡高峰,当天死亡150只。随后死亡数量逐渐下降。…

Disease and destiny-mystery and mastery

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.     

Foot and mouth disease and bluetongue: differences and similarities

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.
