Prevalence of viral pathogens in aborted fetuses and stillborn piglets with reproductive failure in Korea

摘要

Porcine reproductive and respiratory syndrome virus (PRRSV), porcine parvovirus (PPV), enccphalomyocarditis virus (EMCV) and pseudorabies virus (PRV) have been associated with fetal death due to a direct attack on the fetus or the placenta (Holler, 1994). In recent years, porcine circovirus type 2 (PCV2) has also been linked to reproductive failure, with a direct effect on the fetus (West et al., 1999). Some reports also suggest that reproductive failure can be associated with swine influenza outbreak in Europe and in North America (Ronald, 2004). The objective of this study was to determine the presence of viruses known to be present in Korea such as PRRSV, PPV and EMCV, PRV, PCV2 as well as SIV, in tissues from aborted fetuses.
