雏鸭病毒性肝炎和传染性浆膜炎混合感染的诊治

鸭疫里默氏杆菌病（Riemerella anatipes-tifer．RA）又称为鸭传染性浆膜炎，是侵害雏鸭的一种急性或慢性败血性传染病。1932年，由美国学者Herdrikson和Hiben首次在纽约长岛的鸭场中发现，1982年郭玉璞等在北京郊区鸭场分离鉴定出RA血清型为Ⅰ型，RA主要感染家鸭，1～8周龄鸭均可感染，但对2～3周龄的雏鸭最易感，发病率高，一般为60％～70％，有时高达90％。

鸭传染性浆膜炎是由鸭疫里氏杆菌(RA)引起的一种接触性传染病,主要侵害雏鸭、雏鹅等多种禽类,多发于2～7周龄的雏鸭,呈急性或慢性败血症.鸭疫里氏杆菌血清型众多,已经公开报道的就达25种,不同血清型的RA菌株、同一血清型不同源的RA分离菌株,其致病性存在差异,且不同血清型的菌株之间缺乏免疫交叉保护能力.     

鸭传染性浆膜炎防治

1流行病学 本病多发于秋冬之交和春夏之交。一般情况下,本病主要发生于1～8周龄的雏鸭、雏鹅,尤以2～3周龄雏鸭易感,8周龄以上的鸭很少发病。成年鸭少见发病,但可带菌,成为传染源。本病主要经呼吸道或皮肤伤口引起感染,     

一起鸭传染性浆膜炎的诊治

鸭传染性浆膜炎10多年前在尤溪县就有零星发生,一直持续不断,而且最近几年的发病率和死亡率还有逐年提高的趋势.鸭群一旦发病,2～5周龄雏鸭的死亡率可达20%～70%,目前该病已成为尤溪县危害最严重的细菌性传染病之一,给养鸭业造成了巨大的经济损失.鸭传染性浆膜炎是由鸭疫里默氏杆菌引起的一种鸭传染病,主要感染2～3周龄雏鸭,其特征是引起雏鸭纤维素性心包炎、肝周炎、气囊炎和关节炎.现将一起鸭传染性浆膜炎的诊治经过介绍如下.     

间接免疫组化法检测鸭疫里默氏杆菌感染和抗原定位

应用鸭源血清1型鸭疫里默氏杆菌(RA)作为抗原。免疫兔制备兔抗RA的IgG。建立了检测雏鸭感染鸭疫里默氏杆菌的间接免疫酶组织化学法。该法检测大肠杆菌(O1、O8、O79、O138)、鸭沙门氏菌、多杀性巴氏杆菌(5：A)感染发病死亡雏鸭组织。不出现阳性反应，而检测RA感染发病死亡雏鸭组织出现特异性阳性反应；检测RA人工发病死亡雏鸭。可在心脏、肝脏、肺脏、肾脏、十二指肠、盲肠、直肠、脾脏、法氏囊、胸腺、胰脏、脑和腺胃检测到RA抗原，RA抗原分布于细胞浆、组织间隙和血液；检测RA人工感染病例与RA肝脏分离符合率为100％，检测临床可疑病例的血清1型RA的阳性率(92．96％)比细菌分离率(75.12％)高。该法具有特异、直观和敏感的特点，可用于雏鸭RA人工感染和临床感染的诊断、检测及RA抗原定位和RA致病机理的研究。

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.
