“…The virus can agglutinate chicken, guinea pig, mouse, human, monkey, rat, and cat erythrocytes. Thus, hemagglutination inhibition assays (HAI) were developed relatively early [ 64 , 80 ] and they are still used in research and practice in some countries [ 5 , 44 , 81 , 82 ]. Other serological methods like the serum neutralization (SN) assay or the modified direct complement-fixation (MDCF) test were also utilized earlier, but today the enzyme-linked immunosorbent assay (ELISA) is the most frequently applied test to detect PPV-specific antibodies.…”

Porcine parvovirus (PPV) is among the most important infectious agents causing infertility in pigs. Until recently, it was thought that the virus had low genetic variance, and that prevention of its harmful effect on pig fertility could be well-controlled by vaccination. However, at the beginning of the third millennium, field observations raised concerns about the effectiveness of the available vaccines against newly emerging strains. Subsequent investigations radically changed our view on the evolution and immunology of PPV, revealing that the virus is much more diverse than it was earlier anticipated, and that some of the “new” highly virulent isolates cannot be neutralized effectively by antisera raised against “old” PPV vaccine strains. These findings revitalized PPV research that led to significant advancements in the understanding of early and late viral processes during PPV infection. Our review summarizes the recent results of PPV research and aims to give a comprehensive update on the present understanding of PPV biology.

“…Serologic evidence of exposure to Aujeszky's disease virus, encephalomyocarditis virus and porcine parvovirus in wild boar was reported in one study (Jeoung et al, 2015). Notifiable diseases or pathogens for which published evidence was reported in wild boar include Aujeszky's disease, porcine respiratory and reproductive syndrome, classical swine fever and Trichinella spp., which could result in trade embargoes if diagnosed in domestic swine (Choi et al, 2012;Jeoung et al, 2015;Kim et al, 2011;Seo, Sunwoo, Hyun, & Lyoo, 2012). Consequently, the risk of wild boar acting as reservoirs for these diseases of swine production and these pathogens spilling over into domestic swine farms appears to be a concern.…”

Wildlife-associated diseases and pathogens have increased in importance; however, management of a large number of diseases and diversity of hosts is prohibitively expensive. Thus, the determination of priority wildlife pathogens and risk factors for disease emergence is warranted. We used an online questionnaire survey to assess release and exposure risks, and consequences of wildlife-associated diseases and pathogens in the Republic of Korea (ROK). We also surveyed opinions on pathways for disease exposure, and risk factors for disease emergence and spread. For the assessment of risk, we employed a two-tiered, statistical K-means clustering algorithm to group diseases into three levels (high, medium and low) of perceived risk based on release and exposure risks, societal consequences and the level of uncertainty of the experts' opinions. To examine the experts' perceived risk of routes of introduction of pathogens and disease amplification and spread, we used a Bayesian, multivariate normal order-statistics model. Six diseases or pathogens, including four livestock and two wildlife diseases, were identified as having high risk with low uncertainty. Similarly, 13 diseases were characterized as having high risk with medium uncertainty with three of these attributed to livestock, six associated with human disease, and the remainder having the potential to affect human, livestock and wildlife (i.e., One Health). Lastly, four diseases were described as high risk with high certainty, and were associated solely with fish diseases. Experts identified migration of wildlife, international human movement and illegal importation of wildlife as the three routes posing the greatest risk of pathogen introduction into ROK. Proximity of humans, livestock and wildlife was the most significant risk factor for promoting the spread of wildlife-associated diseases and pathogens, followed by high density of livestock populations, habitat loss and environmental degradation, and climate change. This study provides useful information to decision makers responsible for allocating resources to address disease risks. This approach provided a rapid, cost-effective method of risk assessment of wildlife-associated diseases and pathogens for which the published literature is sparse.

“…Although not many countries have searched for PPV in wild boars, one study reported that 44 of 842 wild boars sampled in the Transylvania region of Romania between 2006 and 2011 were positive for PPV [16]. In addition, of the 481 wild boars captured in South Korea from 2010-2011, 29% were seropositive for antibodies against PPV (142/481) [17]. Interestingly, a GenBank search suggested that only PPV1, PPV2, and PPV7 have been detected in Korean domestic pigs [17].…”

Porcine parvovirus 1 (PPV1) is a major cause of reproductive failure in pigs; to date, six novel porcine parvoviruses (PPV2-PPV7) have been identi ed. Here, we detected 11 PPV1, ve PPV3, three PPV4, six PPV5, ve PPV6, and one PPV7 strain in Korean wild boars. PPV1, -3, and -5, and PPV6, from Korean wild boars harbor conserved motifs within the Ca 2+ binding loop and the catalytic center of the PLA1 motif. Intrarecombination among PPV7 strains was also identi ed. Genetic characterization revealed that PPV1 from Korean wild boars may be similar to virulent PPV strains.
