江苏省通州地区鸽消化道蠕虫的初步调查

采用局部蠕虫剖检法对通州地区鸽消化道蠕虫进行了初步调查，共检查到4个科的5种线虫，分别为鸽蛔虫、鸽毛细线虫、膨尾毛细线虫、四射鸟圆线虫和节片戴文绦虫。鸽一般是两种蠕虫同时混合感染，最高可达4种，最高感染强度可达347条，其中鸽蛔虫和鸽毛细线虫为优势虫种，膨尾毛细线虫、四射鸟圆线虫和节片戴文绦虫感染率较低，这为该地区鸽寄生虫的防治提供了一定的依据。     

狐狸肺炎双球菌和巴氏杆菌混合感染的诊治

正肺炎双球菌和巴氏杆菌是危害狐狸养殖的两个主要病原。前者是属于链球菌科链球菌属,主要引起狐狸发生肺炎、败血症、脑膜脑炎、心内膜炎、关节炎等,以肺炎多发。后者感染狐狸主要引起败血症、出血性炎症等,慢性病例也表现皮下组织、关节、各脏器的局灶化脓性炎症,常呈地方流行。这两种病原近年来常呈混合感染,具有发病快、死亡率高、难防治等特点,给养狐业带来严重的经济损失。2017年7月29日,山东一狐狸养殖场发生狐     

鸽子常见疾病的防治

近年来随着肉鸽养殖规模化、集约化的发展,各类鸽病不断扩散,种类也不断增多,有很多病例是由多种病原同时或先后对鸽体侵袭造成混合感染和继发感染。本文根据肉鸽疾病流行情况和发病特点,就养殖户关心的几种常见病防治方法简单介绍如下。     

鸽副粘病毒病和毛滴虫病混合感染的诊治报告

正鸽副粘病毒病、鸽毛滴虫病均是鸽的常见传染病,一旦发病,若处理不当,往往会造成严重损失。特别是这两个病混合感染时,由于叠加作用,增加了临床诊断和防治的困难。现将本人临诊的一例鸽副粘病毒病与鸽毛滴虫病混合感染的情况综合整理报告如下:1鸽场管理及鸽发病情况1.1鸽场管理鸽场为旧厂房改建而成,全场只有一栋鸽舍(砖瓦结构,檐口高4.5m,长48m,宽     

猪圆环病毒2型与链球菌混合感染的诊治

猪圆环病毒2型(PCV2)感染是由PCV2引起的猪的一种免疫抑制性传染病,一旦在猪群中流行,常继发一种或两种以上病原的混合感染,使病情加重,死亡率升高,给养猪造成较大的经济损失。如能及时诊断并采取针对性的防治措施,可使本病得到理想的防治效果。现将笔者经历的一起猪圆环病毒2型与链球菌混合感染的诊治报告如下。1发病情况与症状     

鸽呼吸道疾病的诊断与防治

正鸽子呼吸道感染性疾病,通常是一种多病原微生物诱发的混合感染,是鸽舍中常见的疾病。1发病原因细菌、病毒、支原体、衣原体、寄生虫等多种病原引起,其中以鸽毛滴虫、支原体、衣原体感染最为普遍,平时他们潜伏在健康鸽体内,呈菌群平衡状态,但遇到紧迫、疲劳、气候恶劣、抵抗力减弱、大量微生物入侵时,便会单一或混合发病。     

当前猪病之我见

随着养猪场规模化程度的不断提高,部分养猪场由于防疫措施及病死猪处理不当,一些流行病和传染性较强的疾病呈现多发趋势,且存在交叉感染的现象.根据对河南省南部各县区的疫病流行情况进行分析,猪病流行发生如下变化: 1 多病原混合感染非常普遍 两种或两种以上病原多重(混合)感染非常普遍,病毒与细菌混合感染较多,如猪蓝耳病病毒、猪瘟病毒、猪圆环病毒等与胸膜肺炎放线杆菌、副猪嗜血杆菌、链球菌、肺炎球菌等的混合感染,其中以猪蓝耳病病毒和胸膜肺炎放线杆菌、副猪嗜血杆菌、猪肺炎支原体较多;病毒混合感染如猪蓝耳病病毒、猪瘟病毒、猪圆环病毒混合感染较多,尤其猪蓝耳病病毒和猪圆环病毒混感较多.     

某肉鸽场暴发蛔虫病的诊治

某肉鸽场成年鸽群突发死亡,死亡率为2.5%,临床剖检可见胃肠道大量蛔虫寄生, 应用饱和蔗糖溶液漂浮法对该鸽场共226份粪便样品进行调查,共发现4种蠕虫：蛔虫、圆线虫、绦虫和毛细线虫,感染率分别为39.8%、2.7%、2.7%和2.2%,其中,蛔虫为主要感染虫种,且感染强度较大,确诊该场暴发了蛔虫病。随后对鸽群进行针对性治疗,用药后鸽群未再出现死亡,蛔虫感染率从39.8%下降到19.8%,感染强度明显降低,圆线虫和绦虫未能检出,表明该场鸽肠道寄生蠕虫病得到较好的防治。     

丙硫咪唑驱除肉鸽消化道寄生虫的效果

养鸽业是一项新兴的饲养业,有关鸽的疾病,特别是寄生虫病甚少被注意,为了鲜肉鸽的寄生虫感染情况及药物驱虫效果,我们对杭州某养鸽场进行检查,发现消化道寄生虫的混合感染率高达100％,主要是鸽蛔虫、毛细线虫和棘口吸虫等。严重影响雏鸽的成活率和生长发育及成鸽的生长和产蛋,同时也屡有蛔虫感染而引起肠道穿孔致死的病例。为此,我们应用丙硫咪唑对成年鸽进行了驱虫试验。     

猪高热病的流行特点和防治措施

猪高热病是由急性流感、猪瘟、蓝耳病、圆环病毒、附红细胞体、弓形体、链球菌等多种病原微生物混合感染引起的高感染率、高死亡率、传播速度快的一种疾病.防治猪高热病对保障猪只健康,提高猪只生产效益具有重要意义.     

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.
