Abstrakt: Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus-associated diseases in swine, the most common of which are postweaning multisystemic wasting syndrome (PMWS) and porcine dermatitis and nephropathy syndrome (PDNS). To investigate the prevalence and genetic diversity of PCV2 in Hebei Province, Northern China, from 2016 to 2019, a total of 448 suspected cases of PCV2 infection were studied, and 179 samples were positive for PCV2. A pathological and histopathological examination suggested PCV2 to be cause of the observed lesions. Phylogenetic analysis showed that four genotypes were prevalent in Hebei Province: PCV2a, 2b, 2d, and 2e. Analysis of PCV2 strains using RDP4 and SimPlot showed that there were genetic recombination events among PCV2 strains in Hebei Province. A total of 3284 serum samples were screened by ELISA, and the positive rate of PCV2 antibodies was 73.9% (2428/3284). This study provides a scientific reference for the prevention and treatment of PCV2 in Hebei Province.
