Abstract

Abstract: To understand the current status of common swine diseases in Guangxi, total 325 pig tissue samples were collected from morbidity farms and slaughter houses.CSFV, PRRSV and PEDV were detected by RT-PCR, PCV2 and PRV were detected by PCR.The results showed that the infection rates of those viruses in morbidity farms were 12.00%, 28.57%, 19.43%, 53.71% and 9.71%, respectively, and in the slaughter houses were 5.33%, 2.67%, 5.33%, 59.33% and 11.33%, respectively.The rate of PCV2 coinfection with other virus was the highest.In the morbidity farms, PRRSV+PCV2 was the most universal double infection, which was 11.43%, posteriorly was PEDV+PCV2, CSFV+PCV2 and PCV2+PRV, which were 5.71%, 4.00% and 4.00%, respectively, and PRRSV+PEDV+PCV2 and PRRSV+PCV2+PRV were the most universal tripartite infection, both of them were 2.29%.In the slaughter houses, PCV2+PRV was the most universal double infection, which was 3.33%, CSFV+PCV2+PRV was the most universal triple infection, which was 0.67%.These results indicated that PCV2 had the highest infection rate not only in morbidity farms but also in slaughter houses.PCV2 coinfection with other virus was universal.The infection rate of PRV has risen.It was important to enhance the surveillance of PCV2 and PRV for the control of swine disease in Guangxi.
