一例猪圆环病毒病的诊断与治疗

8一例猪圆环病毒病的诊断与治疗【摘 要】 2011年12月15日至2012年1月15日，笔者在江苏省盐城市某猪场内实习时，该猪场发生一起仔猪传染病。通过临床症状诊断、病理解剖诊断、酶联免疫吸附法诊断等方法确诊为猪圆环病毒病。通过从抗病毒和抗菌结合、治标治本结合、中药西药结合三原则对病猪就行防治，取得了较好的效果。【关键词】 猪；圆环病毒病；诊断；治疗Diagnosis and treatment of a case of porcine circovirus infectionAbstract An outbreak was occurred in a pig farm belonging to Yancheng, Jiangsu province where is practiced in December 15,2011 to January 15,2012. It was determined as porcine circovirus infection based on clinical signs, gross lesions and ELISA detection. So we made a comprehensive treatment including combined usage of anti-virus and anti-bacterial drugs, addressing both the symptoms and root causes, combined usage of Chinese traditional medcine and western medcines. The curative effect was proved to be very good.Keywords: pig porcine circovirus infection diagnosis treatment目 录引言···························································································1文献综述······················································································11 病原学及流行病学特征···································································11.1 病原······················································································11.2 流行病学················································································22 临床症状···················································································22.1 仔猪断奶后多系统衰竭综合征（PMWS）···············································22.2 猪皮炎与肾病综合征(PDNS)···························································22.3 繁殖障碍性疾病········································································22.4 猪呼吸道复合体病（PRDC）····························································32.5 猪增生性肠炎（PPE）···································································32.6 增生性/坏死性肺炎(PNP)······························································32.7 猪传染性先天性震颤（CT）····························································33 病理变化···················································································33.1 断奶仔猪多系统衰竭综合征···························································33.2 猪皮炎与肾病综合征···································································33.3 猪呼吸病综合征········································································44 诊断························································································44.1 临床症状诊断···········································································44.2 病理解剖诊断···········································································44.3 酶联免疫吸附法（ELISA法）··························································44.4 PCR方法·················································································45 防治························································································55.1 预防······················································································55.2 治疗······················································································5正文 ··························································································61 病例介绍···················································································62 临床症状···················································································63 剖解变化···················································································64 诊断························································································64.1 临床症状诊断···········································································64.2 病理解剖诊断···········································································74.3 制备被检血清···········································································74.4 结果······················································································75 治疗························································································75.1 治疗原则················································································75.2 治疗方法················································································76 总结························································································7参考文献······················································································8致谢···························································································8江苏畜牧兽医职业技术学院论文（设计）引 言猪圆环病毒病是由猪圆环病毒2型(PCV-2)感染所致的一种新的病毒性传染病。该病发病率高、传播迅速、易发生继发感染，给养猪业造成严重的经济损失。现已被世界各国的兽医与养猪业者公认为是继猪繁殖与呼吸综合征(PRRS)之后新发现的引起猪免疫障碍的重要传染病。本病一年四季均可发生，主要危害612周龄的仔猪。但在实行早期隔离断奶的猪场，1014日龄的断奶猪也有该病的发生，病毒可随粪便和鼻腔分泌物排出体外，经消化道传播，也可能经胎盘垂直传染仔猪，发病率和死亡率不定。呈地方性流行时，发病率和死亡率均较低，但急性暴发时，发病率可达10%50%，病死率达20%30%。如与猪细小病毒或猪繁殖与呼吸综合征病毒、链球菌、多杀性巴氏杆菌和副猪嗜血杆菌等混合感染时，死亡率会更高；而猪皮炎肾病综合征(PDNS)主要危害生长育肥猪，死亡率为 15%20%。耐过猪发育不良，成年猪一般为隐性感染，不表现任何症状和病变。文献综述猪圆环病毒（Porcine Circovirus PCV）属于圆环病毒科圆
