Abstract
Porcine circovirus type 2 (PCV2) is the causative agent of postweaning multisystemic wasting syndrome (PMWS). In this study, 38 PCV2 cases obtained from different pig farms with different health conditions in Republic of Korea were sequenced and analyzed. Phylogenetic analysis showed that our cases had a greater variation and the existence of two PCV2 groups with at least four subgroups (1A, 1C, 2D, and 2E). Most cases obtained from PMWS-affected herds were in group 1, whereas cases with no clinical signs compatible with PMWS (wasted non-PMWS) were included within group 2. Moreover, four cases from the wasted non-PMWS belonged to PCV2-group 1. Therefore, our results suggest that PCV2-group 1 is more related to PMWS than group 2. Copyright 2009 Elsevier Ltd.
