Abstract

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
