摘要:猪心肌炎病又被称为猪脑心肌炎病,是由病毒感染引发的一种广泛传播的病毒性传染性疾病,该种疾病的致病原为脑心肌炎病毒,典型的临床特征是脑组织发炎和心肌出现炎症。猪感染病毒后,还会不断向外传播病毒,危害某些哺乳类动物。随着生猪规模养殖产业不断扩大,猪心肌炎病的发生几率呈现逐年上升的态势,如果没有做好有效的防范工作,会向周边牲畜传播蔓延,带来的危害严重。该文主要论述猪心肌炎病的流行特点、临床表现、病理特征和防治措施。

Abstract:Porcine myocarditis,also known as porcine encephalomyocarditis,is a widespread viral infectious disease caused by viral infection and is caused by encephalomyocarditis virus,typical clinical features are inflammation of brain tissue and inflammation of the myocardium. Pigs infected with the virus,but also continue to spread the virus,harm some mammals. With the development of large-scale pig breeding industry,the incidence rate of porcine myocarditis is rising year by year. If we don't do effective prevention work,it will spread to the surrounding livestock and bring serious harm. This article mainly discusses the epidemic characteristics,clinical manifestations,pathological features and preventive measures of porcine myocarditis.
Keywords:porcine myocarditis,epidemic characteristics,prevention and treatment
0引言
豬心肌炎是对年龄较小的猪造成严重危害的一类病毒性传染性疾病,主要表现为脑膜心肌出现炎症。该种传染性疾病在世界各地养殖场中普遍发生流行,除威胁猪外,还可危害多种牲畜类动物。各个年龄品种的猪对脑心肌炎病毒的易感性都很强,其中仔猪阶段对病毒的易感性最强,发病率50%,致死率50%以上。2005年猪心肌炎病首次在我国生猪养殖领域报告,随后随着生猪养殖业的不断发展壮大,病毒向周边生猪养殖场快速传播蔓延,并呈现逐年扩大流行的态势,对整个生猪养殖业乃至公共卫生安全构成不良影响。为有效防范猪心肌炎病的发生,流行切断病毒的传播途径,需要加强诸心肌炎病流行病学调查,掌握该类疾病的典型临床特征和病理特征,构建针对合理的防治措施,确保在短时间内控制病情。……
