华南地区猪圆环病毒和猪繁殖与呼吸综合征病毒检测分析 总被引：1，自引：0，他引：1
为了解华南地区猪圆环病毒及猪繁殖与呼吸综合征病毒的最新流行情况,采集了华南地区11个规模猪场各饲养阶段猪血清807份,用套式PCR(nPCR)检测猪圆环病毒1型(PCV-1)和猪圆环病毒2型(PCV-2);采集了若干猪场2010年1月至2011年8月期间有咳嗽、喘气、消瘦及疑似PDNS等临床症状的猪血清312份,以及无临床症状猪血清104份,以nPCR检测PCV-2,以一步法反转录PCR(RT-PCR)检测猪繁殖与呼吸综合征病毒。结果发现,所调查的11个规模猪场中只有5个检出PCV-1,所有猪场均检出PCV-2。PCV-2阳性率为30.61%,而PCV-1阳性率仅为4.21%;经产母猪和7周龄以上保育猪PCV阳性率最高;有临床症状的猪血清PCV-2阳性率为58.65%,PRRSV阳性率为37.82%,PCV-2阳性猪群中有39.89%的猪同时感染PRRSV;有症状猪群7月～9月的PCV-2感染率最高,而1月～3月最低;无临床症状猪血清PCV-2阳性率为27.9%,PRRSV阳性率为0.96%,PCV-2与PRRSV无混合感染。证明PCV尤其是PCV-2在华南地区仍广泛传播并流行,而且PCV-2与PRRSV混合感染致病情况较多。PCV-2的感染率与季节有一定的相关性,种猪带毒情况严重。 相似文献

2012年8月,东莞市某猪场发生了断奶仔猪一起以呼吸道症状,关节炎、发烧等症状的传染病,发病率为40％,死亡率接近10％.经临床诊断、病例解剖,实验室检测,初步诊断为猪蓝耳病并和猪副嗜血杆菌病混合感染.通过紧急免疫接种、药物治疗、和消毒等措施,疫情得到有效控制.
1发病情况
该猪场于2012年7月从广西购进100头猪苗,日龄大概为50～60d,购进回来以后分别免疫了猪瘟、口蹄疫、猪肺疫疫苗,购进回来以前的免疫情况不详.8月初开始,有一栏10多头猪出现发烧、食欲减退、呼吸困难并有关节肿胀、跛行等病状,并有全群扩散的趋势,到8月中旬发病率达到40％. 相似文献

近年来,猪场疫病越来越复杂,猪病常以病毒性与细菌性疫病混合感染的形式出现,疫病防控更加困难,给养猪业造成巨大经济损失。现将一例猪繁殖呼吸障碍综合征(PRRS)与副猪嗜血杆菌病混合感染的诊治情况报道如下。1发病情况与临床症状泉州市某养猪户饲养母猪105头,自繁自养。该猪场按常规方法进行了猪瘟、伪狂犬病免疫,母猪有进行高致病性蓝耳病疫苗免疫,仔猪未免。 相似文献

近年来,进入10月份后,规模化猪场猪病多以表现高热症状为主的混合感染,控制难度越来越大.猪瘟、蓝耳病、副猪嗜血杆菌病频发,免疫抑制普遍存在,呼吸道疾病有所抬头,霉菌毒素危害呈现越来越严重的发展态势.为此,具体分析病情,确定灵活的控制措施,已是规模化猪场迫在眉睫的任务. 相似文献

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. 相似文献

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. 相似文献
