“…Others have also shown geographical and age variation in the prevalence of the virus [6,8,12]. Higher positivity was detected in adults than in wild boars less than one year of age, as was also observed in our study.…”

“…This high level of homology among P-PARV4 isolates from different parts of the world suggests a high species specificity of the virus with a low mutation frequency [6]. However, more data on P-PARV4 in wild animals are needed to investigate the evolution of this new virus [6].…”

“…However, the most recent report of the International Committee on Taxonomy of Viruses (ICTV) [2] did not include this virus or the suggested genus Hokovirus in the family Parvoviridae. Several names for porcine hokovirus have been proposed, such as ''porcine parvovirus type 3'' (PPV3) [3,4], ''porcine partetravirus'' [5,6] and ''porcine PARV4'' [7]. More recently, a review group of members of the ICTV submitted a proposal to update the taxonomy of the family Parvoviridae.…”

Porcine hokovirus in wild boar in Portugal

Porcine hokovirus (PHoV), also referred to as porcine parvovirus 4 (P-PARV4), a recently discovered parvovirus of swine that is closely related to human parvovirus 4/5 (H-PARV4/5), was first described in Hong Kong. To evaluate the occurrence of P-PARV4 in Portuguese wild boars in the hunting season of 2011/2012, liver and serum samples were tested. P-PARV4 was detected in 24 % of the wild boars analyzed. Phylogenetic analysis showed a close relationship between the P-PARV4 isolates and other P-PARV4 reference strains. This virus appears to be emerging, with yet unknown implications for public health.

“…The Thai PPV3s were related to many PPV3s from Europe , Germany , the USA , Hong Kong and China (Fig. ), but appeared to be most related to two UK PPV3s (FJ982254 and FJ982251) with a 0.8–2.0% nucleotide difference and two Cameroon PPV3s (KF225548 and KF225549) with a 2.8–4.8% nucleotide difference.…”

Porcine parvovirus (PPV) causes reproductive failure in sows and has spread worldwide. Several new types of porcine parvoviruses have recently been identified in pig herds. The prevalence of five porcine parvoviruses in the Chiangmai area of Thailand was studied. The prevalence in 80 pigs was 53% for PPV (PPV-Kr or -NADL2 being the new abbreviations), 83% for PPV2 (CnP-PARV4), 73% for PPV3 (P-PARV4), 44% for PPV4 (PPV4), and 18% for PBo-likeV (PBoV7). Over 60% of the pigs carried more than three of the five porcine parvoviruses and occurrence together of the two pairs of viral genes, PPV1/PPV3 and PPV2/PBo-likeV were observed. Phylogenetic analyses for PPV2 and PPV3 indicated the existence of only two major clades of PPV2 and one major clade of PPV3.

Ungulate tetraparvovirus 2 (UTV2), formerly known as porcine hokovirus due to its discovery in Hong Kong, is closely related to a Primate tetraparvovirus (human PARV-4) and Ungulate tetraparvovirus 1 (bovine hokovirus). Until now, UTV2 was detected in European, Asian and North American countries, but its occurrence in Latin America is still unknown. This study describes the first report of UTV2 in Brazil, as well as its phylogenetic characterization. Tissue samples (lymph node, lung, liver, spleen and kidney) of 240 piglets from eight different herds (30 animals each herd) were processed for DNA extraction. UTV2 DNA was detected by PCR and the entire VP1/VP2 gene was sequenced for phylogenetic analysis. All pigs from this study displayed postweaning multisystemic wasting syndrome (PMWS). UTV2 was detected in 55.3% of the samples distributed in the variety of porcine tissues investigated, as well as detected in almost all herds, with one exception. The phylogenetic analysis demonstrated that Brazilian UTV2 sequences were more closely related to sequences from Europe and United States.
