Abstract:
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.
