摘要/Abstract

摘要：

引起猪病毒性腹泻的病原主要有猪流行性腹泻病毒（porcine epidemic diarrhea virus，PEDV）、猪传染性胃肠炎病毒（transmissible gastroenteritis virus，TGEV）及猪轮状病毒（porcine rotarvirus，PoRV），临床均以呕吐、严重腹泻和脱水为特征，哺乳仔猪发病率和病死率较高，后备猪、母猪或育肥猪呈一过性腹泻，发病率较低。特别是自2010年以来，PEDV变异毒株的流行已对全球的生猪产业造成严重影响，而已有的防控措施已经不能应对新的流行态势。近年来，针对PEDV、TGEV、PoRV的毒株流行变化及防控措施研究的较多，许多新技术、新方法已应用于3种病原的控制。作者基于当前3种病毒的遗传变异分析和流行现状，从饲养管理、免疫预防、中药疗法、干扰疗法、特异疗法及返饲疗法等方面对防控措施进行综述，以期为猪病毒性腹泻的防控提供科学依据。

Abstract:

PEDV,TGEV and PoRV are the main pathogenies of porcine viral diarrhea that endanger the healthy development of swine industry,which are characterized by vomiting,severe diarrhea and dehydration, the morbidity and mortality of suckling piglets is higher,and the incidence of diarrhea is lower in replacement gilts,sows or fattening pigs. Especially since 2010, the prevalence of PEDV mutant strains has had a serious impact on the global swine industry,but the control measures can not been able to cope with the new epidemic situation. In recent years, many new techniques or methods have been applied to the control of swine viral diarrhea caused by PEDV, TGEV and PoRV. Based on the analysis of genetic variation and epidemic status of three kinds of viruses,this paper reviewed the prevention and control measures from the aspects of feeding management,immunization prevention, traditional Chinese medicine therapy,interference therapy,specific therapy and return therapy.

Key words: porcine epidemic diarrhea virus (PEDV); transmissible gastroenteritis virus (TGEV); porcine rotarvirus (PoRV); epidemic status; prevention and controlling strategies
