摘要/Abstract

摘要： 为了解中国江苏省及周边地区猪场断奶仔猪多系统衰竭综合征(PMWS)相关病原的流行情况,本研究采用PCR方法,对2014年1月至2015年5月采自江苏、安徽及浙江等地猪场的125份健康猪样品和261份发病猪样品分别进行猪圆环病毒2型(PCV2)、猪繁殖与呼吸综合征病毒(PRRSV)、猪细小病毒(PPV)、输血性传播病毒(TTV)和类猪圆环病毒P1的检测。结果显示,所有样品PCV2、PRRSV、PPV、TTV1、TTV2和P1的阳性率分别为39.38%、21.76%、3.11%、15.80%、16.32%和10.10%,其中混合感染主要存在于PMWS的发病猪群,以PCV2与TTV2 (15.32%)和PCV2与PRRSV (11.87%)的混合感染为主。结果表明,江苏省及周边地区猪场普遍存在PMWS相关病原的混合感染现象,加大了PMWS相关病原的防控难度。

Abstract: To investigate the epidemiology of multi-pathogens related with post-weaning multi-systemic wasting syndrome (PMWS) in Jiangsu province and surrounding areas,125 healthy samples and 261 diseased samples which obtained in Jiangsu,Anhui and Zhejiang provinces from the January 2014 to May 2015 were screened by PCR for the presence of PCV2,PRRSV,PPV,TTV and P1.These results revealed the following infection rates of PCV2,PRRSV,PPV,TTV1,TTV2 and P1 were 39.38%,21.76%,3.11%,15.80%,16.32% and 10.10%,respectively.In comparison,the co-infection of several viruses occurred in the diseased pigs,and the main co-infections were PCV2+TTV2 (15.32%) and PCV2+PRRSV (11.87%).These observations indicated that the phenomenon of co-infection with multi-pathogens had been widely existing in swine,which increased the difficulty of prevention and controlling of the PMWS.

Key words: post-weaning multi-systemic wasting syndrome; multi-pathogens co-infection; epidemiological investigation
