A large-scale epidemiological study of porcine circovirus-like virus P1 was carried out from 2007 to 2015 in China, which revealed a high level of P1 infection. Thirty-nine sequences obtained from pigs in eastern China showed remarkable genetic diversity, with the P1 predominant sequences and the mutant P1 with ORF1 or ORF2 containing an additional amino-acid extension at the C-terminus. This information may be useful for understanding the evolution of P1 circovirus-like virus.
2007年至2015年期间，在中国开展了一项关于猪圆环病毒样病毒P1的大规模流行病学研究，该研究揭示了P1的高感染水平。从中国东部猪群中获得的39个序列显示出显著的遗传多样性，包括P1优势序列以及ORF1或ORF2在C端含有额外氨基酸延伸的P1突变体。这些信息可能有助于了解P1圆环病毒样病毒的进化。
