灾后谨防畜禽黄曲霉素中毒

灾后收获的玉米、高梁等谷物饲料,由于含水量高,贮藏不善,容易生长黄曲霉。黄曲霉毒素是黄曲霉的一种产物,畜禽食人带有黄曲霉素的饲料就会引起黄曲霉毒素中毒。     

雏鹅黄曲霉毒素中毒的诊治

黄曲霉毒素中毒是畜禽的一种中毒性疾病,是由于畜禽食入被黄曲霉或寄生曲霉产生的黄曲霉毒素污染的饲料引起。这两种霉菌能产生一组毒性极强的代谢产物,其中黄曲霉毒素B1（AFTB1）的毒性最大。黄曲霉毒素主要对肝脏造成损害,可引起肝细胞变性、坏死。临床上以肝功能障碍、全身出血、消化机能紊乱、腹水、神经症状等为特征。

黄曲霉毒素对畜禽的危害与防制

饲料中黄曲霉毒素不仅关系到畜禽动物的安全和生产效率,更直接影响人们的身体健康和生命安全。本文综述了黄曲霉毒素对畜禽的危害及其机制,提出防制饲料黄曲霉毒素中毒的对策措施。     

畜禽黄曲霉毒素中毒的症状与防治

黄曲霉毒素中毒是人畜共患且有严重危害性的霉败饲料中毒病。该毒素主要引起畜禽肝细胞变性、坏死、出血，胆管和肝细胞增生。畜禽临床上以全身出血，消化机能紊乱，腹水，神经症头等为特征。各种畜禽均可发生本病，但由于性别、年龄及营养状况不同，其敏感性也有差别。幼龄动物一般比成年动物敏感，高蛋白饲料可降低动物对黄曲霉毒素的敏感性。     

秋季谨防畜禽黄曲霉毒素中毒

黄曲霉毒素是黄曲霉菌的代谢产物,具有致癌作用,可导致畜禽和人类肝损害和肝癌,对人畜危害极大.由于黄曲霉菌最适宜的繁殖温度为24～30℃,相对湿度为80%以上,秋季因多雨最易感染黄曲霉菌的玉米、豆类、花生饼等畜禽主要饲料极易发生霉败.这些霉败饲料饲喂畜禽后,可导致畜禽黄曲霉毒素中毒,且奶牛食入黄曲霉毒素后,可由奶中分泌黄曲霉毒素,危害人体健康.现将畜禽黄曲霉毒素中毒的发病状况及防治措施介绍如下:

饲料防霉拮抗菌的筛选

正畜禽饲料在储藏过程中十分容易受黄曲霉等霉菌的污染,产生次级代谢物黄曲霉毒素(Aflatoxins),不仅可引起各种动物的急性、慢性中毒,而且具有致癌、致畸、致突变的作用,饲料中黄曲霉毒素在畜禽类产品中聚积,最终也会威胁到人类健康。鉴于此,本研究以黄曲霉等引起饲料霉变的常见霉菌为靶标,利用对峙培养法和抑菌圈法,     

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.
