Abstract

Abstract: The research was to study the epidemiology of co-infection of porcine circovirus type 2 and Porcinereproductive and respiratory syndrome virus in parts of China during 2009 － 2010． A total of 227 tissue and serumsamples of diseased pigs obtained from Jiangsu， Anhui， Shanghai， Shandong， Zhejiang， Fujian and Jiangxi provincesof China during 2009 － 2010 were detected for PCV2 and PRRSV by PCR or RT-PCR． The results showed that thepositive rate of PCV2a， PCV2b and PRRSV were 15． 9% ， 44． 5% and 45． 8% respectively． 17 samples were positive for PCV2a and PRRSV， 50 samples were positive for PCV2b and PRRSV， 10 samples were positive for PCV2a，PCV2b and PRRSV， and the corresponding co-infection rate were 7． 5% ， 22． 0% and 4． 4% respectively． All theseresults indicated that the PCV2 and PRRSV infection were widespread and co-infection of PCV2 and PRRSV wasprevalent in parts of China during 2009 － 2010． The high co-infection rate also increased the difficulty of preventionand controlling diseases of swine．
