Abstract excerpt
GP5, the most important neutralizing antigen of porcine reproductive and respiratory syndrome virus (PRRSV), has the highest genetic diversity among isolates. To more fully understand the extent of genetic diversity of PRRSV in China, we analyzed and compared the GP5 sequences of 42 PRRSV isolated from 1996 to 2006 in mainland China. We found that all of the Chinese isolates examined belong to the North American...
