Abstract
The complete genome sequences of a porcine circovirus type 1 (PCV1) strain isolated in 1990 and one isolated in 2011 were obtained and compared to the sequences of other available PCV1 isolates. Phylogenetic analyses revealed very low genetic diversity among these viruses, indicating an advanced state in the evolution of PCV1.
摘要
获得了1990年分离的一株猪圆环病毒1型（PCV1）和2011年分离的另一株PCV1的全基因组序列，并与其他可用的PCV1分离株的序列进行了比较。系统发育分析表明，这些病毒之间的遗传多样性非常低，这表明PCV1的进化处于高级阶段。
