猪圆环病毒病流行病学、临床症状和防治

Epidemiology,Clinical Symptoms and Prevention of Porcine Circovirus Disease

猪圆环病毒病是由圆环病毒二型感染引发的一种免疫抑制性疾病,该种疾病虽然造成的死亡率较低,但是会严重侵染猪的免疫系统,造成身体抵抗能力下降,给多种病原微生物的繁殖侵染提供条件,临床上主要表现为高发病率,严重损害免疫系统使的猪群的生产性能显著下降,仔猪受到病毒侵染后,死亡率会进一步升高,对整个生猪养殖产业造成的经济损失不可估量。猪圆环病毒病在猪群中一旦传播流行,将需要消耗更多的时间用于猪群的净化处理,否则会导致猪反复传播该种疾病,威胁严重。该文主要论述养殖场猪圆环病毒病的流行与防治过程。

Porcine circovirus is an immunosuppressive disease caused by infection with circovirus type 2,which,although less fatal,severely affects the immune system of pigs and causes a decline in body resistance,to provide conditions for the reproduction and infection of a variety of pathogenic microorganisms,the clinical manifestations are mainly high incidence rate,severe damage to the immune system,resulting in a significant decline in the production performance of pigs,piglets infected with the virus,the mortality will further increase,the economic loss caused to the whole pig breeding industry is inestimable.Once porcine circovirus becomes endemic in pigs,it will take more time to decontaminate the herd,which could lead to repeated transmission of the disease by pigs,which is a serious threat.This paper mainly discusses the epidemic and control process of porcine circovirus disease in farm.
