  • Glycyrrhizin inhibits porcine epidemic diarrhea virus infection and
           attenuates the proinflammatory responses by inhibition of high mobility
           group box-1 protein
    • Authors: Chang-chao Huan; Hua-xia Wang; Xiang-xiang Sheng; Rui Wang; Xin Wang; Xiang Mao
      Pages: 1467 - 1476
      Abstract: Abstract Porcine epidemic diarrhea (PED), caused by porcine epidemic diarrhea virus (PEDV) infection, leads to significant economic losses in the swine industry worldwide. In our studies, we found that glycyrrhizin, the major component of licorice root extracts, could moderately inhibit PEDV infection in Vero cells, when analyzed by western blot, qRT-PCR and a plaque formation assay. We also revealed that glycyrrhizin inhibited the entry and replication of PEDV. In addition, we demonstrated that glycyrrhizin decreased the mRNA levels of proinflammatory cytokines. Since glycyrrhizin is a competitive inhibitor of high mobility group box-1 (HMGB1), we confirmed that TLR4 and RAGE (£ associated with PEDV pathogenesis during the infection in Vero cells. In summary, our studies provide a molecular basis for developing novel therapeutic methods to control PEDV infection, based on glycyrrhizin and its derivatives.

  • HIV-1 genetic diversity and transmitted drug resistance frequency among
           Iranian treatment-naive, sexually infected individuals
    • Authors: Rouhollah Vahabpour; Farah Bokharaei-Salim; Saeed Kalantari; Saba Garshasbi; Seyed Hamidreza Monavari; Maryam Esghaei; Arash Memarnejadian; Atousa Fakhim; Hossein Keyvani
      Pages: 1477 - 1485
      Abstract: Abstract In recent years, the patterns of human immunodeficiency virus 1 (HIV-1) transmission in Iran have been changing gradually from drug injection to unprotected sexual contact. This study sought to investigate the phylogenetic trends and characteristics of transmitted drug resistance (TDR) mutations of HIV-1 in a population that is mainly infected through homo/heterosexual contacts. Sixty newly diagnosed antiretroviral-naive individuals with HIV infection living in Tehran were recruited to this survey, and among them, 42 subjects were established to be infected through sexual intercourse. Following amplification and sequencing of the main part of the HIV-1 pol region, phylogenetic and drug-resistance mutation (DRM) analysis was successfully performed on these 42 patients. Phylogenetic analysis showed that the majority of the subjects were infected with subtype CRF35_AD (88%), followed by subtype B, with 7.1%, and subtype CRF01_AE, with 4.7%. A total of 7.1% of the subjects were found to be infected with HIV-1 variants with surveillance drug-resistant mutations (SDRMs) according to the last world health organisation (WHO) algorithm. All of the identified SDRMs belonged to the non-nucleoside reverse transcriptase inhibitors (NNRTIs) class, including K103 N and V106A, which were found in three patients. Two minor HIV protease-inhibitor-related mutations (L10I and G73S) were detected in two patients, but these mutations are not included in the WHO SDRMs list. The dominance of HIV-1 subtype CRF35_AD was observed among subjects of this study who were infected through sexual contact. The moderate prevalence of SDRMs (7.1%) in this population emphasises the fact that the risk of treatment failure in HIV-infected individuals might increase in the future, and preventive measures should be considered by health authorities.

  • miR-146a negatively regulates the induction of proinflammatory cytokines
           in response to Japanese encephalitis virus infection in microglial cells
    • Authors: Minnan Deng; Ganqin Du; Jiegang Zhao; Xiaowei Du
      Pages: 1495 - 1505
      Abstract: Abstract Increasing evidence confirms the involvement of virus infection and miRNA, such as miR-146a, in neuroinflammation-associated epilepsy. In the present study, we investigated the upregulation of miR-146a with RT-qPCR and in situ hybridization methods in a mice infection model of Japanese encephalitis virus (JEV) and in vitro. Subsequently we investigated the involvement of miR-146a in modulating JEV-induced neuroinflammation. It was demonstrated that JEV infection promoted miR-146a production in BALB/c mice brain and in cultured mouse microglial C8-B4 cells, along with pro-inflammatory cytokines, such as IL-1β, IL-6, TNF-α, IFN-β and IFN-α. We also found that miR-146a exerted negative regulatory effects upon IL-1β, IL-6, TNF-α, IFN-β and IFN-α in C8-B4 cells. Accordingly, miR-146a downregulation with a miR-146a inhibitor promoted the upregulation of IL-1β, IL-6, TNF-α, IFN-β and IFN-α, whereas miR-146a upregulation with miR-146a mimics reduced the upregulation of these cytokines. Moreover, miR-146a exerted no regulation upon JEV growth in C8-B4 cells. In conclusion, JEV infection upregulated miR-146a and pro-inflammatory cytokine production, in mice brain and in cultured C8-B4 cells. Furthermore, miR-146a negatively regulated the production of JEV-induced pro-inflammatory cytokines, in virus growth independent fashion, identifying miR-146a as a negative feedback regulator in JEV-induced neuroinflammation, and possibly in epilepsy.

  • Impairment of infectious laryngotracheitis virus replication by deletion
           of the UL[-1] gene
    • Authors: M. Nadimpalli; S. W. Lee; J. M. Devlin; J. R. Gilkerson; C. A. Hartley
      Pages: 1541 - 1548
      Abstract: Abstract Infectious laryngotracheitis virus (ILTV) encodes several unique genes, including a pair of unique nuclear proteins UL0 and UL[-1] that are expressed during replication in cell culture. Although the UL0 gene has been shown to be dispensable for replication, the role of UL[-1] has not been elucidated. In this study a deletion mutant of ILTV lacking the UL[-1] gene was constructed using homologous recombination. The coding sequences of the gene were replaced with the gene for enhanced green fluorescent protein and the cytomegalovirus major immediate early promoter element. The progeny virus carrying the reporter gene was readily identified using fluorescent microscopy, but was unable to propagate in the permissive cells in the absence of wild type ILTV. Even after plaque purification and fluorescent associated cell sorting the recombinant virus deficient in UL[-1] gene could not be successfully isolated. Our findings suggest that the UL[-1] gene has an important role in ILTV replication.

  • Virus surveys of Capsicum spp. in the Republic of Benin reveal the
           prevalence of pepper vein yellows virus and the identification of a
           previously uncharacterised polerovirus species
    • Authors: Leonard Afouda; Daouda Kone; Valerien Zinsou; Laurence Dossou; Lawrence Kenyon; Stephan Winter; Dennis Knierim
      Pages: 1599 - 1607
      Abstract: Abstract Surveys were conducted in 2014 and 2015 in Southern and Northern Benin, respectively, to identify the viruses infecting peppers (Capsicum spp.). The samples were screened by ELISA for cucumber mosaic virus (CMV), pepper veinal mottle virus (PVMV), potato virus Y (PVY) and tomato yellow leaf curl virus (TYLCV). A generic reverse transcription PCR (RT-PCR) was used to test for the presence of poleroviruses. ELISA tests confirmed the prevalence of all viruses, while the RT-PCR detected pepper vein yellows virus (PeVYV) which is reported for the first time in Benin. A further, divergent polerovirus isolate was detected from a single pepper sample originating from southern Benin. Screening of samples collected from solanaceous plants during virus surveys in Mali (conducted in 2009) also detected this divergent polerovirus isolate in two samples from African eggplants. The complete genome sequence was obtained from the Mali isolate using transcriptome sequencing and by conventional Sanger sequencing of overlapping RT-PCR products. Based on the sequence characteristics of this isolate we propose a new polerovirus species, African eggplant yellowing virus (AeYV).

  • Characterization of Epstein-Barr virus-encoded small RNA gene variations
           in virus associated lymphomas in Northern China
    • Authors: Zhenzhen Zhao; Lingling Sun; Song Liu; Jun Shu; Bing Luo
      Pages: 1609 - 1616
      Abstract: Abstract Epstein-Barr virus (EBV)-encoded small RNAs (EBER1 and EBER2) are highly expressed in all forms of EBV latency in EBV-associated malignancies. EBER gene variations and their association with EBV-associated disease still remain poorly characterized. To investigate the patterns of EBER gene variations and their roles in tumorigenesis, EBER gene sequences were analyzed by nested-PCR and DNA sequencing in 101 lymphomas from Northern China, a non-nasopharyngeal carcinoma (NPC) endemic area. In addition, EBV type 1 and type 2 classifications were made by using nested-PCR assays across type-specific regions in the EBNA2 gene. EB-6m was the dominant subtype (95.0%, 96/101) in lymphoma. The distribution of the EBER subtypes in the four lymphoma groups was not significantly different (p > 0.05), neither was that of the EBNA2 type (p > 0.05). Compared with previous data in the same area, the distribution of EBER subtypes in lymphoma was similar to that in EBV-associated gastric carcinoma (EBVaGC) and throat washing (TW) from healthy donors (p > 0.05), but was significantly different from that of NPC. The EBNA2 type distribution between lymphoma and the other three groups was significantly different (p < 0.05). The proportion of type 1 and type 2 dual infections was higher in lymphoma than that in GC, NPC and TW. The mutation 7123nt A → T was identified in 11 of 101 (10.9%, 11/101) lymphomas, significantly more than that in EBV-associated gastric carcinomas (EBVaGC) (0%, 0/50) and throat washings (TWs) from healthy donors (3.3%, 3/92) (p < 0.05). These findings indicate that EBER subtypes may not be associated with pathogenesis of lymphoma, but that a point mutation at position 7123nt (A → T) provides a new area for further exploration. Furthermore it is necessary to investigate the role of EBNA2-subtype mixed infections in the establishment of lymphoma.

  • Simultaneous detection of severe acute respiratory syndrome, Middle East
           respiratory syndrome, and related bat coronaviruses by real-time reverse
           transcription PCR
    • Authors: Ji Yeong Noh; Sun-Woo Yoon; Doo-Jin Kim; Moo-Seung Lee; Ji-Hyung Kim; Woonsung Na; Daesub Song; Dae Gwin Jeong; Hye Kwon Kim

      Abstract: Abstract Since severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) coronaviruses (CoVs) share similar characteristics with respect to clinical signs, etiology, and transmission, methods for a rapid and accurate differential diagnosis are important. Therefore, the aim of this study was to develop a duplex real-time reverse transcription (RT)-PCR method for the simultaneous detection of these viruses. Primers and probes that target the conserved spike S2 region of human SARS-CoV, MERS-CoV, and their related bat CoVs were designed. The results of real-time RT-PCR showed specific reactions for each virus with adequate detection limits of 50–100 copies/mL and 5–100 copies/mL using pUC57-SARS-pS2 (a template for SARS-CoV) and pGEM-MERS-S2 (a template for MERS-CoV), respectively. In addition, this real-time RT-PCR system was able to detect the target viruses SARS-like bat CoV and MERS-CoV in bat fecal samples and sputum of MERS patients, respectively. Therefore, this newly developed real-time RT-PCR method is expected to detect not only SARS-CoV and MERS-CoV in humans but also several bat CoVs that are closely related to these viruses in bats.

  • The “Giant Virus Finder” discovers an abundance of giant viruses in
           the Antarctic dry valleys
    • Authors: Csaba Kerepesi; Vince Grolmusz
      Pages: 1671 - 1676
      Abstract: Abstract Mimivirus was identified in 2003 from a biofilm of an industrial water-cooling tower in England. Later, numerous new giant viruses were found in oceans and freshwater habitats, some of them having 2,500 genes. We have demonstrated their likely presence in four soil samples taken from the Kutch Desert (Gujarat, India). Here we describe a bioinformatics work-flow, called the “Giant Virus Finder” that is capable of discovering the likely presence of the genomes of giant viruses in metagenomic shotgun-sequenced datasets. The new workflow is applied to numerous hot and cold desert soil samples as well as some tundra- and forest soils. We show that most of these samples contain giant viruses, especially in the Antarctic dry valleys. The results imply that giant viruses could be frequent not only in aqueous habitats, but in a wide spectrum of soils on our planet.

  • Complete genome sequence of a hepatitis B virus isolate of genotype D2,
           subtype adrq + , from Brazil
    • Authors: Natália Spitz; Aline S. Moreira; Francisco C. A. Mello; Helena Cristina F. Franz; Selma A. Gomes; Natalia M. Araujo
      Pages: 1695 - 1700
      Abstract: Abstract Hepatitis B virus (HBV) has been classified into 10 distinct serological subtypes of the surface antigen (HBsAg) that can be predicted by sequencing of the corresponding S gene. HBV genotype D usually displays determinants of subtypes ayw2 or ayw3. On the other hand, subtype adrq+ has been found exclusively in association with genotype C. Here, we describe the first HBV genome (isolate BR32) belonging to genotype D with the serological subtype adrq+. This isolate had a genome length of 3,062 nucleotides (nt), and no recombination events were observed in the BR32 genome that could explain the occurrence of the subtype adr in a genotype D isolate. Analysis of the quasispecies population revealed that 28 out of 30 clones (93%) were of subtype adrq+, while the subtypes of the two remaining could not be determined, since they contained an S residue (instead of K or R) at position 122 of HBsAg. These results will contribute to further epidemiological and evolutionary studies of HBV.

      Abstract: Abstract To determine the role of systemic injection of rabies immunoglobulin (RIG) in rabies vaccination, we analyzed the level of antibody against rabies virus in the serum of mice that received various doses of RIG combined with rabies vaccine. Our results indicate that systemic injection of RIG does not contribute detectably to passive or adaptive immunization, suggesting that the main function of RIG in individuals with category III exposure is to neutralize rabies virus via immediate local infiltration of the wound.

  • Complete genome sequence and analysis of blackcurrant leaf chlorosis
           associated virus, a new member of the genus Idaeovirus
    • Authors: Delano James; James Phelan
      Pages: 1705 - 1709
      Abstract: Abstract Blackcurrant leaf chlorosis associated virus (BCLCaV) was isolated from symptomatic blackcurrants (Ribes nigrum cv. Baldwin). The virus has a genome organization similar to that of raspberry bushy dwarf virus (RBDV), the type member of the genus Idaeovirus. The RNA-1of this virus encodes the replicase complex (ORF1, Mr 197 kDa), while RNA-2 encodes a putative movement protein (ORF2a, Mr 38.8 kDa) and the putative coat protein (ORF2b, Mr 30 kDa). A concatenated form of BCLCaV RNA-2 was detected by next-generation sequencing and confirmed by RT-PCR. BCLCaV is a new member of the genus Idaeovirus.

  • Antiviral effects of extracts from Celosia cristata and Raphanus sativus
           roots against viral hemorrhagic septicemia virus
    • Authors: Yeon Jung Park; Chiung Moon; Jung-Ha Kang; Tae-Jin Choi
      Pages: 1711 - 1716
      Abstract: Abstract The antiviral activity of an extract mixture from Celosia cristata and Raphanus sativus was tested against viral hemorrhagic septicemia virus (VHSV). Pretreatment of EPC cells with this extract up to 72 h before VHSV infection markedly reduced the virus titer, but it had no effect when added after virus inoculation. In olive flounder that received 5 µg of extract per fish, Mx expression peaked at 48 h after treatment. In contrast, ISG15 and TLR2 expression peaked at 72 h, and that of TLR7 peaked at 48 h, followed by a slight decrease at 72 h, indicating that the antiviral activity was mediated by induction of gene expression involved in the innate immune response.

  • Genotype analysis of ORF 62 identifies varicella-zoster virus infections
           caused by a vaccine strain in children
    • Authors: Byung Ok Kwak; Hoan Jong Lee; Hyun Mi Kang; Chi Eun Oh; Eun Hwa Choi
      Pages: 1725 - 1730
      Abstract: Abstract This study was performed to differentiate vaccine-type strains from wild-type strains and determine the genotype of varicella-zoster virus (VZV) in 51 Korean children. A sequencing analysis of ORF 62 identified two cases of herpes zoster caused by the vaccine-type virus, without a previous history of varicella, 22 months and 5 months after VZV vaccination. The wild-type strain was identified in the remaining children. A genotype analysis of ORF 22 amino acids revealed genotype J in all children except one. Genotype E was identified in an infant with varicella imported from Egypt.

  • Complete nucleotide sequence of Solanum nodiflorum mottle virus
    • Authors: Merike Sõmera; Erkki Truve
      Pages: 1731 - 1736
      Abstract: Abstract Solanum nodiflorum mottle virus (SNMoV) was isolated from a small-flowered nightshade (Solanum nodiflorum) in Queensland, Australia. It has been included in the genus Sobemovirus based on virion morphology and serological relationships. Here, we report the sequence of the complete genome of SNMoV. Sequence analysis confirmed that SNMoV has the characteristic genome organization of sobemoviruses. Phylogenetic analysis showed that it clusters most closely with velvet tobacco mottle virus (VTMoV), another sobemovirus native to Australia. Their genomes show 56.8 % sequence identity.

  • Detection of a novel gammaherpesvirus (genus Rhadinovirus ) in wild
           muntjac deer in Northern Ireland
    • Authors: John McKillen; Kayleigh Hogg; Paula Lagan; Cheryl Ball; Simon Doherty; Neil Reid; Lisa Collins; Jaimie T. A. Dick
      Pages: 1737 - 1740
      Abstract: Abstract This study represents the initial part of an investigation into the potential for non-native, wild, free-living muntjac deer (Muntiacus reevesi) to carry viruses that could be a threat to livestock. A degenerate PCR assay was used to screen a range of tissues from muntjac deer culled in Northern Ireland for the presence of herpesviral nucleic acids. This was followed by sequencing of PCR amplicons and phylogenetic analysis. We report the detection of a novel gammaherpesvirus most closely related to a type 2 ruminant rhadinovirus from mule deer. It remains to be determined if this new virus is pathogenic to deer or presents a risk to food security through the susceptibility of domestic livestock.

  • Genetic diversity, distant phylogenetic relationships and the occurrence
           of recombination events among cucumber mosaic virus isolates from zucchini
           in Poland
    • Authors: Beata Hasiów-Jaroszewska; Mateusz Chrzanowski; Daria Budzyńska; Natalia Rymelska; Natasza Borodynko-Filas
      Pages: 1751 - 1756
      Abstract: Abstract In recent years, the occurrence of cucumber mosaic virus (CMV) has been noted in zucchini crops in Poland. Beside characteristic isolates, which displayed mosaics and chlorosis on infected plants, new necrotic isolates have also been identified. Here, we analysed the molecular variability of 27 isolates of CMV collected from zucchini in various regions of the country. Sequence and phylogenetic analysis based on the genes encoding the coat (CP) and movement (MP) proteins revealed that the Polish isolates belong to two subgroups: IA and II, with the prevalence of subgroup II. New recombinant variants with an IA-MP/II-CP pattern for RNA3 were also detected.

  • Full-genome sequencing and phylogenetic analysis of four neurovirulent
           Mexican isolates of porcine rubulavirus
    • Authors: Ali A. Garcia-Barrera; Alberto Del Valle; Juan A. Montaño-Hirose; Blanca Lilia Barrón; Juana Salinas-Trujano; Jesus Torres-Flores
      Pages: 1765 - 1768
      Abstract: Abstract We report the complete genome sequences of four neurovirulent isolates of porcine rubulavirus (PorPV) from 2015 and one historical PorPV isolate from 1984 obtained by next-generation sequencing. A phylogenetic tree constructed using the individual sequences of the complete HN genes of the 2015 isolates and other historical sequences deposited in the GenBank database revealed that several recent neurovirulent isolates of PorPV (2008-2015) cluster together in a separate clade. Phylogenetic analysis of the complete genome sequences revealed that the neurovirulent strains of PorPV that circulated in Mexico during 2015 are genetically different from the PorPV strains that circulated during the 1980s.

      Pages: 1783 - 1786
      Abstract: Abstract Cacipacoré virus (CPCV) is a potential emerging virus classified in the genus Flavivirus, family Flaviviridae. In the present study, we present the genetic characterization of a CPCV isolated from ticks (Amblyomma cajennense) collected from a sick capybara (Hydrochoerus hydrochaeris) in São Paulo State, Brazil. The CPCV isolate shares the typical genomic organization of flaviviruses with 10,857 nucleotides in length and a single open reading frame of 10,284 nucleotides encoding a polyprotein of 3,427 amino acids. Phylogenetic analysis revealed that CPCV is unique, as a potentially tick-borne virus, in the Japanese encephalitis virus serogroup.

      Abstract: Abstract A high diversity of begomoviruses that infect non-cultivated plants has been noted in Brazil. Here, we report the complete sequences of two new species of bipartite begomoviruses from Sida sp. plants collected in the state of Piauí, northeastern Brazil. The genomes of these viruses show a genomic organization that is typical of New World begomoviruses. In phylogenetic analysis, two closely related viruses (sida angular mosaic virus, SiAMV and sida chlorotic vein virus, SiCVV) clustered with other begomoviruses described in tomato and Sida plants in Brazil. Evidence of recombination is shown among isolates of the species described.

  • Next generation sequencing and molecular analysis of artichoke Italian
           latent virus
    • Authors: Toufic Elbeaino; Imen Belghacem; Tiziana Mascia; Donato Gallitelli; Michele Digiaro
      Pages: 1805 - 1809
      Abstract: Abstract Next-generation sequencing (NGS) allowed the assembly of the complete RNA-1 and RNA-2 sequences of a grapevine isolate of artichoke Italian latent virus (AILV). RNA-1 and RNA-2 are 7,338 and 4,630 nucleotides in length excluding the 3’ terminal poly(A) tail, and encode two putative polyproteins of 255.8 kDa (p1) and 149.6 kDa (p2), respectively. All conserved motifs and predicted cleavage sites, typical for nepovirus polyproteins, were found in p1 and p2. AILV p1 and p2 share high amino acid identity with their homologues in beet ringspot virus (p1, 81% and p2, 71%), tomato black ring virus (p1, 79% and p2, 63%), grapevine Anatolian ringspot virus (p1, 65% and p2, 63%), and grapevine chrome mosaic virus (p1, 60% and p2, 54%), and to a lesser extent with other grapevine nepoviruses of subgroup A and C. Phylogenetic and sequence analyses, all confirmed the strict relationship of AILV with members classified in subgroup B of genus Nepovirus.
