猪轮状病毒病的防制

猪轮状病毒病，也称轮状病毒性腹泻，是由猪轮状病毒（RV）引起的一种急性肠道传染病。一般仔猪发病较多，青年猪和成年猪患病较少，且多为隐性感染，不表现症状。该病潜伏期较短，一般为12～24h。临床上以呕吐、腹泻、脱水和酸碱平衡紊乱为特征。本病在世界各地养猪场内普遍存在，我国也已确认猪感染本病毒引起发病。

猪轮状病毒的分离与电镜观察

近年来,北京地区猪轮状病毒感染,不仅严重威胁养殖业的发展,同时威胁到肉食品和人类的安全。取胶体金抗原检测为阳性的2头哺乳仔猪病料用Marc-145细胞培养,分离到1株轮状病毒,连续盲传至4代出现细胞病变,用Marc-145细胞进行病毒噬斑纯化,挑取单克隆病毒株扩大培养后,将病毒感染Marc-145细胞7 d后,应用Reed-Muench法计算轮状病毒TCID50为106.6/0.1 mL,用感染细胞超薄切片进行电镜观察,可见典型的晶格状排列的轮状病毒粒子,为轮状病毒感染的诊断提供了科学依据。     

应用ELISA法、RT-PCR法检测固原市部分地区肉牛轮状病毒的研究

为了探析固原地区肉牛轮状病毒病的流行情况及临床意义,采集宁夏固原市部分地区500头腹泻病牛粪样,首先用酶联免疫吸附试验(ELISA)进行轮状病毒检测,再用RT-PCR法进行核酸复检。结果表明:所有采集的500份粪样中,用ELISA检测出128份轮状病毒粪样,阳性率为25.6%;用RT-PCR检测出141份轮状病毒粪样,阳性率为28.2%。说明:轮状病毒是导致固原地区肉牛腹泻的主要病原微生物;ELISA法和RT-PCR法结合应用检测肉牛轮状病毒效果良好。

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.
