摘要： A total of 450 samples from domestic pigs in China were tested for porcine parvoviruses (PPVs) and co-infections with porcine circovirus type 2 (PCV2), and their complete capsid genes were sequenced. The prevalence of PPV1, PPV2, PPV3, PPV4, and PCV2 was 5.56 %, 39.56 %, 45.11 %, 21.56 %, and 47.33 %, respectively, and co-infection with PCV2 occurred in 4 % (PPV1), 22.44 % (PPV2), 24 % (PPV3), and 12 % (PPV4) of the samples. Phylogenetic analysis revealed two main lineages for each virus, and residues that differentiated these viruses were identified. The co-infections of emerging PPVs and PCV2 were prevalent, indicating their cooperative roles in porcine circovirus-associated diseases.
