1500 sow pig farm livestock on hand more than a head of long years of slaughter pigs 3000, in the right sub-weaned pigs inactivated vaccine of highly pathogenic blue-ear disease the day after immunization and found that some sub-pig feed intake decreased, followed by temperature increased up to 41 ℃, and the succession of death, as of the author-spot investigation at diagnosis, before and after the death of half of a total of 431 head of pigs, the mortality rate as high as 80.49%. 针对上述暴发的疫情，通过流行病学调查、临床症状和病死猪剖解变化，最终采集病料在实验室诊断，结论是猪场发生了以高致病性猪蓝耳病疫情为主，伴发猪瘟、猪伪狂犬病和细菌性混合感染的一起疫情。
In response to these outbreaks of the epidemic, through the epidemiological investigation, clinical symptoms and Bing Sizhu dissect changes, eventually collecting material in the laboratory diagnosis of disease and concluded that the pig farm there was an outbreak of highly pathogenic PRRS mainly associated with Classical swine fever, swine pseudorabies and mixed infection with the bacterial outbreak. 基本情况某标准化种猪场，按照免疫程序使用由政府采购提供的某企业生产的批号为20080717080737的高致病性蓝耳病灭活疫苗，免疫子猪523头。
The basic situation of a standardized pig farm, according to immunization programs used by the government procurement provided for a batch production of the highly pathogenic blue-ear disease 20080717080737 inactivated vaccine, the immune sub-pig 523. 免疫后18小时~24小时，部分子猪出现食欲不振、体温升高并伴有眼结膜潮红、咳嗽气喘、磨牙、转圈和站立不稳等神经症状，第三天开始出现零星死亡，随即对未发病猪群饲料投药预防，并对已发病猪群采取对症治疗，每天进行全场消毒并对死亡猪进行深埋或焚烧处理。
18 hours after immunization to 24 hours, some sub-pigs lack of appetite, fever, accompanied by conjunctival flushing, cough, asthma, teeth, turning in circles and standing instability and other neurological symptoms began to appear sporadically on the third day death, then for failure to Pig feed Dosing disease prevention, and incidence of pigs have been taken to symptomatic treatment, disinfection daily audience as well as the death pigs buried or incinerated.当时场主顾虑影响末引起足够重视。
At that time the market impact of the end of the main concerns of adequate attention. 10天后，子猪开始批量死亡，方才求诊于笔者。
10 days, the pigs began to mass death of the child before an attendance at the writer. 病理剖解变化病死猪消瘦，两耳和四肢末端以及躯干部发绀，有的通体潮红，现场共解剖病死猪7头，大体病理解剖病变可以见到腹股沟淋巴结高度水肿，气管喉头充血出血，肺部病变尤其突出、肺实变、水肿、肺间隔增宽，心脏变薄无力、心包积液，有血性胸水渗出，与胸膜粘连，肾脏苍白或呈现土黄色，发育畸形，表面有针尖大出血点，脾脏周边梗死出血、部分猪脾脏肿大，肝肿有灰白色和灰黄色的小点坏死灶，胃肠道呈现片状潮红、出血，消化道黏膜脱落，回盲瓣扣状结节、坏死，膀胱充盈有散在性出血点等病理变化。
Pathological changes of Bing Sizhu dissect thin, ears and limbs and the trunk end of cyanosis, and some quintana flushing, the scene of anatomy Bingsi Zhu 7, in general pathological anatomy pathological inguinal lymph node can be seen a high degree of edema, congestive heart bleeding throat trachea, lung lesions particularly conspicuous, lung consolidation, edema, pulmonary intervals widened, heart thinning weakness, pericardial effusion, with bloody pleural effusion, and pleural adhesions, kidney or present earth pale yellow, developmental deformities, the surface of the tip bleeding points, spleen around the infarct hemorrhage, part of the pig spleen enlargement, liver swollen with gray and sallow dot necrosis, gastrointestinal tract, rendering sheet flushing, bleeding, gastrointestinal mucosa off, ileocecal valve button-like nodules, necrosis, bladder filling there are scattered bleeding points, such as pathological changes. 化验室诊断采集2头份病死猪病变肺组织和淋巴结组织作为送检病料，在实验室进行PCR检测。
Laboratory diagnosis of collecting two copies of Bing Sizhu lesions in lung tissue and lymph node disease as the submission materials, in the laboratory PCR. 结果显示：2份病料高致病性猪蓝耳病变异株呈阳性反应。
The results showed that: two copies of the highly pathogenic disease is expected mutant PRRS positive. 诊断结论通过流行病学调查、临床症状和对病死子猪临床剖检以及查阅现场疫情照片及档案资料，临床和实验室初步诊断结论为：造成431头断奶子猪陆续死亡的直接原因是，该猪场发生了以高致病性猪蓝耳病疫情为主，同时伴有猪瘟、猪伪狂犬病和细菌性疾病混合感染的一起疫情。
Diagnosis Conclusion epidemiological investigation, clinical symptoms and the clinical anatomy of the dead child, as well as access to on-site pig epidemic photographs and archival material, an initial diagnosis of clinical and laboratory findings as follows: create 431 pigs weaned child is the direct cause of death after another, the pig farm there was an outbreak of highly pathogenic PRRS mainly accompanied by classical swine fever, swine pseudorabies and bacterial diseases with the outbreak of mixed infection. 防治建议1.猪场猪舍环境消毒。
Prevention and treatment recommendations 1. Pig pig environmental disinfection. 2.隔离病猪，对症治疗减少损失。
2. Isolation pigs, symptomatic treatment to reduce losses. 3.搞好猪群的疫病预防接种工作首先，选用由洛阳普莱柯生物工程有限公司生产的高效价猪瘟疫苗（细胞源）和猪高致病性蓝耳病灭活疫苗（普宁），解决好猪瘟和猪蓝耳病的免疫，并用其公司生产的高效价猪伪狂犬病活疫苗（普宁）对能繁母猪、后备母猪按疫苗使用要求进行免疫接种。
3. Do a good job of the disease pigs vaccinated in the first place, chosen by the Bio-Engineering Co., Ltd. Luoyang Pulai Ke production of high titers of classical swine fever vaccine (cell-derived) and the highly pathogenic blue-ear pig disease inactivated vaccine (Puning), solve the classical swine fever and swine blue ear disease immunity, and with his company produced high titers of porcine pseudorabies vaccine (Puning) to be able to fan sows, sows reserve requirements by vaccine immunization. :tiphat:http://translate.googleusercontent....le.com&usg=ALkJrhi_GdM9sC21iTj99s4foPtyv6OsHA</TD></TR></TBODY></TABLE></TD></TR></TBODY></TABLE>
