Abstract
Hepatitis E virus (HEV) is an important cause of acute viral hepatitis in humans worldwide. The food-borne transmission of HEV appears to be a major route in Europe through the consumption of pork and wild boar meat. HEV epidemiology in wild boars has been investigated mainly in Northern and Central Italian regions, whilst information from Southern Italy is limited. We investigated the occurrence of HEV in wild boar in the Apulia and Basilicata regions (Southern Italy). Thirteen (10.4%) out of one hundred and twenty-five wild boar samples tested positive for HEV using a quantitative reverse transcription PCR. HEV prevalence was 12% in Apulia and 9.3% in Basilicata. Seven samples were genotyped, and different subtypes (c, f, m) of genotype 3 were identified. The complete genome of a 3m strain was determined, and the virus showed the highest nucleotide identity to a human HEV strain identified in France in 2017. These findings demonstrate the substantial circulation of HEV in the wild boar population in Italian Southern regions. Gathering information on the HEV strains circulating in different geographical areas is useful for tracking the origin of HEV outbreaks and assessing the epidemiological role of wild boar as a potential virus reservoir for domestic pigs.

Abstract
Porcine cytomegalovirus (PCMV), a porcine roseolovirus (PRV) that is closely related to human herpesviruses 6 and 7, is commonly found in commercial pigs. PCMV/PRV is important in xenotransplantation, because in preclinical trials in which pig organs were transplanted into non-human primates, transmission of PCMV/PRV was shown to be associated with significantly reduced survival of the xenotransplants. PCMV/PRV was also transmitted in the first transplantation of a pig heart into a human patient worldwide and apparently contributed to the death of the patient. The prevalence of PCMV/PRV in wild boars is largely unknown. In this study, we screened wild boars from several areas of northern Italy and Germany to test for the presence of PCMV/PRV using PCR-based and Western blot assays. By Western blot analysis, 54% and 82% of Italian and German wild boars, respectively, were found to be PCMV/PRV positive, while 36% and 60%, respectively, tested positive by real-time polymerase chain reaction (PCR). These data indicate that the virus is common in German and Italian wild boars and that the Western blot assay detected a PCMV/PRV infection more often than did real-time PCR. The data also indicate that pigs raised for xenotransplantation should be protected from contact with materials from wild boars and commercial pigs.

Abstract
During the ongoing COVID-19 pandemic, along with the SARS-CoV-2 infection, another zoonotic origin virus emerged: monkeypox virus. Researchers are trying to screen the wild animals to pinpoint the exact origin of these viruses in both cases. For SARS-CoV-2, scientists who were studying the zoonotic transfer of the virus are currently divided along four distinct lines: the first group suspects the pangolin as the source of the SARS-CoV-2 virus; the second one is the bat origin of the virus; the third group includes both the pangolins and bat, and fourth group informed about the origin of several other animals. Similarly, scientists have noted significant host ranges of the virus for the monkeypox virus, such as monkeys, chimpanzees, rodents, prairie dogs, etc. Therefore, we should understand some essential points of the zoonosis of these two important viruses, such as animal origin, natural reservoir, intermediate hosts, virus spillover events (spillover time, and frequency of infecting the one host to another or reservoir to human), etc. We appeal for long-term monitoring through the teamwork of scientists involving the fields of wildlife biology, veterinary medicine,molecular biology, virology, health science, and computational biology. It is essential to create an integrated multi-national scientific task force with adequate funding from all countries originating in the regions of these two viruses. It could explore the mechanisms involving not only the SARS-CoV-2 and monkeypox virus origin, host range, and all spillover events of these viruses but also the future outbreak of wildlife-based epidemics.

Genetic Diversity and Epidemiological Significance of Wild Boar HEV-3 Strains Circulating in Poland. Viruses 2021; 13:v13061176.

Abstract
The wild boar is the most important reservoir of zoonotic HEV-3 strains among different wildlife species. The aim of the study was subtype identification of wild boar HEV-3 strains circulating in Poland. Wild boar liver was used in the study in the form of homogenates prepared from 57 samples positive for HEV in a real-time RT-PCR. These samples were collected from juvenile and adult wild boars hunted in the jurisdictions of different Regional Directorates of State Forests (RDSF) across Poland. Subtype identification of detected HEV strains was based on a phylogenetic analysis of the most conserved HEV ORF2 genome fragment. Out of 57 tested samples, consensus HEV ORF2 sequences of 348 bp were obtained for 45 strains. Nineteen strains were identified and belonged to the HEV gt 3a and 3i subtypes, whereas 26 were not assigned to any virus subtype. HEV gt 3i strains prevailed in the Polish wild boar population, 16 of such were identified, and they were significantly more often observed in the RDSF Katowice area (χ2 = 28.6, p = 0.027 (<0.05)) compared to other regions of the country. Circulation of 3a strains was limited only to the RDSF Gdańsk territory (χ2 = 48, p = 0.000 (<0.05)). The virus strains detected in the Polish population of wild boars representing previously identified HEV subtypes in wild boars, pigs, or humans in Europe are of epidemiological importance for public health.

Abstract
In industrialized countries, hepatitis E is now recognized as an emerging zoonosis. Autochthonous cases have been increased over recent years in Europe and are mainly associated with HEV-3 infections. Pigs and wild boars are considered the main reservoirs of the zoonotic HEV-3 and HEV-4 genotypes. Over the past decade, the number of wild boars has drastically increased in Europe. Due to habitats closer to humans and domestic animals, the role of wild boar as a reservoir of the zoonotic HEV is considered to be an emerging issue. In this study, we investigated the presence of HEV RNA by a real-time RT-PCR assay in paired liver and muscle samples collected from 196 wild boars (Sus scrofa) hunted in the two areas of Central and Southern Italy. Twenty animals (10.2%) were HEV RNA positive in livers, 11 of which were also positive in muscles. The ORF2 and ORF1 partial viral sequences were obtained for nine paired livers and muscles, and when aligned were identical to each other. Phylogenetic analyses confirmed detection of different HEV-3 subtypes: 3c, 3f, 3i and some that were not assigned to any subtypes that have so far been identified. Results need further investigation because they are based on analyses of sequences of short genome regions. Nevertheless, we observed that the same strains were circulating in the wild boar populations from the two investigated areas, confirming persistence of the same HEV strains in the wild boar population over time.
