Porcine circovirus type 2 (PCV2) is a major causative agent of postweaning multisystemic wasting syndrome (PMWS). Sequence and phylogenetic analyses based on the ORF2 capsid protein gene fragment showed that field isolate in Republic of Korea (ROK), PCV2 YJK 0703, was closely related with the PCV2 Fh18 isolate. PCV2 YJK 0703 was genetically distinct and not related to previously reported ROK isolates. Therefore, genotypic variation exists among prevailing PCV2 in ROK. This result suggests that several PCV2 genotypes exist in Korean pig farms.
