  • Contradictory intrahepatic immune responses activated in high-load
           hepatitis C virus livers compared with low-load livers
    • Authors: Mariko Ishibashi; Hiromi Yamaguchi; Yukari Hirotani; Akihisa Sakurada; Toshihide Endo; Masahiko Sugitani; Tadatoshi Takayama; Makoto Makishima; Mariko Esumi
      Pages: 855 - 865
      Abstract: We found a HLA class II histocompatibility antigen gene, DQ alpha 1 chain (HLA-DQA1), that was expressed more than 9-fold higher in high-load hepatitis C virus (HCV) livers than low-load HCV livers using transcriptomics of chronic HCV-infected livers. To further investigate this finding, we examined which cells were positive for HLA-DQA1 and what liver immune responses were different between HCV-high and -low livers. HLA-DQA1-positive cells were significantly increased in the HCV-high group, and most positive cells were identified as non-parenchymal sinusoid cells and lymphocytic infiltrates in the portal area. Parenchymal hepatocytes were negative for HLA-DQA1. HLA-DQA1-positive cells in the liver sinusoid were positive for CD68 (macrophages or Kupffer cells); those in the lymphocytic infiltrates were positive for CD20 (B cells) or CD3 (T cells). mRNA levels of antigen-presenting cell (APC) markers such as CD68 and CD11c were significantly upregulated in the HCV-high group and were correlated with HLA-DQA mRNA levels. CD8B mRNA (CD8+ T cells) was upregulated in both HCV-positive livers compared with HCV-negative livers, whereas CD154 mRNA (CD4+ T helper cell) was upregulated in the HCV-high group compared with the HCV-low group. The immune regulatory molecules FOXP3 mRNA (regulatory T cell, T reg) and programmed cell death ligand-1 (PD-L1) mRNA were significantly increased in the HCV-high group. HCV-high livers had two molecular immune responses: increased APC numbers and adaptive immunity and the induction of immune tolerance. The local hepatic imbalance of contradictory immune responses might be responsible for high HCV loads.

      Abstract: Dengue virus (DENV) infection is a worldwide public health problem, which can cause severe dengue hemorrhagic fever (DHF) and life-threatening dengue shock syndrome (DSS). There are currently no anti-DENV drugs available, and there has been an intensive search for effective anti-DENV agents that can inhibit all four DENV serotypes. In this study, we tested whether vivo-morpholino oligomers (vivo-MOs), whose effect on DENV infection has not previously been studied, can inhibit DENV infection. Vivo-MOs were designed to target the top of 3’ stem-loop (3’ SL) in the 3’ UTR of the DENV genome and tested for inhibition of DENV infection in monkey kidney epithelial (Vero) cells and human lung epithelial carcinoma (A549) cells. The results showed that vivo-MOs could bind to a DENV RNA sequence and markedly reduce DENV-RNA, protein, and virus production in infected Vero and A549 cells. Vivo-MOs at a concentration of 4 µM could inhibit DENV production by more than 104-fold when compared to that of an untreated control. In addition, vivo-MOs also inhibited DENV production in U937 cells and primary human monocytes. Therefore, vivo-MOs targeting to the 3’ SL in the 3’ UTR of DENV genomes are effective and have the potential to be developed as anti-DENV agents.

  • Genetic characterization of low-pathogenic avian influenza viruses
           isolated on the Izumi plain in Japan: possible association of dynamic
           movements of wild birds with AIV evolution
    • Authors: Hiroko Nakagawa; Kosuke Okuya; Toshiko Kawabata; Aya Matsuu; Kozo Takase; Masakazu Kuwahara; Shigehisa Toda; Makoto Ozawa
      Pages: 911 - 923
      Abstract: The Izumi plain in Kagoshima Prefecture, Japan, is an overwintering site of endangered cranes (hooded cranes and white-naped cranes) and of many other migratory birds (including wild ducks) that are considered carriers of avian influenza viruses (AIVs). To assess the risks of a highly pathogenic avian influenza outbreak in the crane populations, we tested various environmental samples for AIVs in this area. In the 2014–2015 winter season, we isolated one AIV of the H6N2 subtype from the cranes’ roost water and two AIVs of the H11N9 subtype from a crane fecal sample and a cloacal swab of a dead spot-billed duck. Genetic analysis of these AIV isolates indicated that our H6N2 isolate is genetically close to AIVs isolated from wild birds in Southeast Asian countries, except that the PB1 and NS genes belong to the North American virus lineage. All genes of the two H11N9 isolates are related to AIVs belonging to the Eurasian virus lineage. Notably, in our phylogenetic trees, H11 HA and N9 NA genes showing high sequence similarity to the corresponding genes of isolates from wild birds in South Africa and Spain, respectively, did not cluster in the major groups with recent wild-bird isolates from East Asia. These results suggest that AIVs with viral gene segments derived from various locations and bird species have been brought to the Izumi plain. These findings imply a possible association of dynamic movements of wild birds with AIV evolution.

  • Role of ribavirin in the treatment of hepatitis C virus-associated mixed
           cryoglobulinemia with interferon-free regimens
    • Authors: Lucio Boglione; Jessica Cusato; Simone Mornese Pinna; Amedeo De Nicolò; Giuseppe Cariti; Giovanni Di Perri; Antonio D’Avolio
      Pages: 961 - 967
      Abstract: Mixed cryoglobulinemia (MC) is the most common extrahepatic manifestation of chronic hepatitis C (CHC), with the presence of symptoms in 10–15% of cases. There have been encouraging data regarding immunological and clinical responses in patients treated with the novel combinations of direct-acting antivirals (DAAs), but the role of ribavirin (RBV) in the treatment of MC has not yet been demonstrated. We prospectively enrolled 132 patients affected by MC and CHC, and virological, immunological and clinical responses were evaluated at 12 weeks after completion of treatment. All subjects were treated with interferon (IFN)-free regimens according to clinical guidelines, with or without RBV. All patients achieved a virological response. A complete immunological response (CR) was observed in 71 subjects (53.8%), a partial response in 44 (33.3%), and no response in 17 (12.8%). Ten patients showed a complete resolution of symptoms (7.6%), and 31 showed a significant improvement (23.5%). CR was significantly higher in patients taking RBV (71.1 vs. 44.8%, p < 0.001) and in treatment-naïve patients (62.5 vs. 43.3%, p < 0.001). In logistic regression analysis, duration of HCV infection of less than 20 years (OR 2.448; 95% IC 1.335–6.202; p = 0.019), treatment-naïve status (OR 2.885; 95% IC 1.404–9.660; p = 0.025) and the use of RBV (OR 6.961; 95% IC 3.912–26.885; p < 0.001) were predictors of CR. In MC patients, IFN-free regimens are effective and well tolerated, and RBV seems to significantly increase the immunological response and promote a decline in cryocrit.

  • Comparative evaluation of the Omniplex-HPV and RFMP HPV PapilloTyper for
           detecting human papillomavirus genotypes in cervical specimens
    • Authors: Young Ahn Yoon; Bo-Hyun Kim; Su-Hak Heo; Hwi Jun Kim; Young-Jin Choi
      Pages: 969 - 976
      Abstract: Human papillomavirus (HPV) is a major cause of cervical neoplasia development. HPV screening is very important because early treatment can prevent cervical cancer. Omniplex-HPV is a polymerase chain reaction followed by Luminex xMAP bead microarray technology that is designed for detecting 40 HPV genotypes. The aim of this study is to evaluate the analytical and clinical performance of the Omniplex-HPV in comparison with that of the commercially available RFMP (restriction fragment mass polymorphism) HPV PapilloTyper. A total of 2,808 cervical swab specimens were obtained. Of these, only 1799 specimens had a cytology result. A type-specific direct sequencing test was performed using the reference method in case of discrepancies between the two test results. The overall percent agreement (OPA) between Omniplex-HPV and RFMP HPV PapilloTyper was 97.9% (κ=0.84; 95% CI: 0.81-0.88). The positive percent agreement (PPA) and the negative percent agreement (NPA) were 98.0% and 96.2%, respectively. The Omniplex-HPV and RFMP HPV PapilloTyper showed comparable sensitivities (90.2% and 91.9%, respectively) and specificities (91.3% each), while the Omniplex-HPV produced more accurate results and required less turnaround time and labor. The agreement between these two methods was excellent for HPV genotyping (P>0.05; McNemar’s test), and clinical sensitivity, specificity, and odds ratio of the two assays were comparable to the result of cytology tests in identifying high risk HPV. In conclusion, Omniplex-HPV and RFMP HPV PapilloTyper were highly comparable with regard to detection and genotyping analysis of HPV.

  • DCAF1 is involved in HCV replication through regulation of miR-122
    • Authors: Yanling Yan; Conghui Li; Binlian Sun; Rongge Yang
      Pages: 977 - 985
      Abstract: Hepatitis C virus (HCV) is a worldwide threaten to human health with a high ratio of chronic infections. Recently, we found that Vpr-mediated regulation of HCV replication depends on the host protein DDB1-Cul4 associate factor 1 (DCAF1), implying that DCAF1 might be involved in the replication of HCV. In this study, we demonstrated that DCAF1 knockdown reduced HCV replication both in the infectious (JFH1) and replicon (Con1) systems. Further investigation showed a negative regulation of HCV internal ribosome entry site (IRES)-mediated translation by DCAF1. Considering the positive effects on the replication of the HCV replicon, we speculated that DCAF1 affected the balance between HCV RNA replication and protein translation. Since miR-122 is involved in the regulation of this balance, we investigated the influence of DCAF1 on miR-122 expression. By measuring the expression of miR-122, pre-miR-122 and its target CAT-1 mRNA, we found that miR-122 was downregulated following DCAF1 knockdown. Furthermore, overexpression of miR-122 rescued HCV replication impairment induced by DCAF1 knockdown. In conclusion, our study suggests that DCAF1 is involved in HCV replication through regulation of miR-122 and thus provides new insights into the interaction between HCV and the host cell.

  • Antiviral effect of lithium chloride on replication of avian leukosis
           virus subgroup J in cell culture
    • Authors: Kun Qian; Xiaowei Cheng; Danyang Zhang; Hongxia Shao; Yongxiu Yao; Venugopal Nair; Aijian Qin
      Pages: 987 - 995
      Abstract: Lithium chloride (LiCl) has been reported to possess antiviral activity against several viruses. In the current study, we assessed the antiviral activity effect of LiCl on ALV-J infection in CEF cells by using real-time PCR, Western blot analysis, IFA and p27 ELISA analysis. Our results showed that both viral RNA copy number and protein level decreased significantly in a dose and time dependent manner. Time-course analysis revealed that the antiviral effect was more pronounced when CEFs were treated at the post infection stage rather than at early absorption or pre-absorption stages. Further experiments demonstrated that LiCl did not affect virus attachment or entry, but rather affected early virus replication. We also found that inhibition of viral replication after LiCl treatment was associated with reduced mRNA levels of pro-inflammatory cytokines. These results demonstrate that LiCl effectively blocked ALV-J replication in CEF cells and may be used as an antiviral agent against ALV-J.

  • Computational analysis of the effect of polymerase acidic (PA) gene
           mutation F35L in the 2009 pandemic influenza A (H1N1) virus on binding
           aspects of mononucleotides in the endonuclease domain
    • Authors: Dipali Bhoye; Sarah S Cherian
      Pages: 1031 - 1036
      Abstract: An F35L mutation in the N-terminal domain of the polymerase acidic protein (PA-Nter), which contains the active site of the endonuclease, has been reported to result in higher polymerase activity in mouse-adapted strains of the 2009 pandemic influenza A H1N1 virus. We modeled wild and mutant complexes of uridine 5’-monophosphate (UMP) as the endonuclease substrate and performed molecular dynamics simulations. The results demonstrated that the F35L mutation could result in a changed orientation of a helix containing active site residues and improve the ligand affinity in the mutant strain. This study suggests a molecular mechanism of enhanced polymerase activity.

      Abstract: To establish an association between mitochondrial dysfunction and apoptosis following infectious bronchitis virus (IBV) infection, HD11 avian macrophage cells were infected with the Massachusetts 41 (M41) strain. Our results show that the M41 strain of IBV induced cytopathic effects followed by the release of new viral particles. Elevated numbers of apoptotic cells were observed at 24, 48 and 72 h post-infection (p.i.). Viral infection was associated with mitochondrial membrane depolarization and reactive oxygen species (ROS) production at all of the examined timepoints p.i. In summary, IBV M41 replication in infected HD11 macrophages seems to induce mitochondrial bioenergy failure, acting as a respiratory chain uncoupler, without compromising viral replication.

      Abstract: A closed-tube reverse transcription loop-mediated isothermal amplification (CT-RT-LAMP) assay was developed for the detection of yam mosaic virus (YMV, genus Potyvirus) infecting yam (Dioscorea spp.). The assay uses a set of six oligonucleotide primers targeting the YMV coat protein region, and the amplification products in YMV-positive samples are visualized by chromogenic detection with SYBR Green I dye. The CT-RT-LAMP assay detected YMV in leaf and tuber tissues of infected plants. The assay is 100 times more sensitive in detecting YMV than standard RT-PCR, while maintaining the same specificity.

  • Polymerase chain reaction-based detection of myc transduction in feline
           leukemia virus-infected cats
    • Authors: Ryosuke Sumi; Ariko Miyake; Taiji Endo; Yoshiharu Ohsato; Minh Ha Ngo; Kazuo Nishigaki
      Pages: 1073 - 1077
      Abstract: Feline lymphomas are associated with the transduction and activation of cellular proto-oncogenes, such as c-myc, by feline leukemia virus (FeLV). We describe a polymerase chain reaction assay for detection of myc transduction usable in clinical diagnosis. The assay targets c-myc exons 2 and 3, which together result in a FeLV-specific fusion gene following c-myc transduction. When this assay was conducted on FeLV-infected feline tissues submitted for clinical diagnosis of tumors, myc transduction was detected in 14% of T-cell lymphoma/leukemias. This newly established system could become a useful diagnostic tool in veterinary medicine.

  • Virome analysis of lily plants reveals a new potyvirus
    • Authors: Yongqiang Li; Anning Jia; Yan Qiao; Jun Xiang; Yongjiang Zhang; Wenhe Wang
      Pages: 1079 - 1082
      Abstract: Lily plants exhibiting virus-like symptoms of leaf yellowing, twisting and brownish necrotic spots were collected, and next-generation sequencing of small RNAs was conducted to identify the associated viruses. Cucumber mosaic virus, lily symptomless virus and a hitherto unrecorded potyvirus, tentatively named “lily yellow mosaic virus” (LYMV), were detected. The genomic RNA of LYMV was 9811 nt in length, encoding a large polyprotein of 3,124 amino acids with a predicted Mr of 353.3 kDa. BLAST analysis showed that LYMV shared a high degree of amino acid sequence identity with Thunberg fritillary mosaic virus (55%), bean yellow mosaic virus (52%), clover yellow vein virus (51%), leek yellow stripe virus (51%), and lily mottle virus (52%), and these viruses clustered together in a phylogenetic tree.

  • Complete genome sequence and analysis of ictalurid herpesvirus 2
    • Authors: Réka Borzák; Tibor Haluk; Dániel Bartha; Andor Doszpoly
      Pages: 1083 - 1085
      Abstract: Ictalurid herpesvirus 2 (IcHV-2) has been causing substantial losses in the black bullhead aquaculture industry since the 1990s. Using next-generation sequencing, the genome of IcHV-2 was completely sequenced and analysed in this study. The complete genome was found to be 142,925 bp in size, containing 77 predicted protein-coding regions, including 12 ORFs that appear to have a homologue in every alloherpesvirus genome sequenced to date. The genome organization of the IcHV-2 shows high similarity to that of IcHV-1, the founding member of the genus Ictalurivirus within the family Alloherpesviridae. A unique sequence region of 101 kbp is flanked by terminal direct repeats of 20 kbp. Thirteen of the 77 putative genes do not show homology to any known genes with sequences in public databases; six of them are found in the repeat regions. Analysis of the whole genome confirms the previously established taxonomic position of IcHV-2.

  • Molecular characterization of a putative gammapartitivirus in the
           phytopathogenic fungus Nigrospora oryzae
    • Authors: Jin Xiu Yu; Jun Zi Zhu; Ying Wang; Chao Jun Zhang; Jie Zhong; Hong Jian Zhu; Bi Da Gao; Qian Zhou
      Pages: 1091 - 1095
      Abstract: We report the molecular attributes of a novel bisegmented double-stranded RNA (dsRNA) virus, designated “Nigrospora oryzae partitivirus 1” (NoPV1), from a phytopathogenic fungus Nigrospora oryzae. The genome of NoPV1 contains two dsRNA segments (dsRNA1 and 2), 1875 bp and 1601 bp in length, respectively. dsRNA1 and -2 both have a single open reading frame encoding the RNA-dependent RNA polymerase and coat protein, respectively. NoPV1 has a high degree of sequence identity to members of genus Gammapartitivirus in the family Partitiviridae. This is the first report of a mycovirus in the family Partitiviridae that infects N. oryzae.

  • Complete genomic sequence of Raphanus sativus cryptic virus 4 (RsCV4), a
           novel alphapartitivirus from radish
    • Authors: Laurence Svanella-Dumas; Sébastien Theil; Matthieu Barret; Thierry Candresse
      Pages: 1097 - 1100
      Abstract: The present work reports the discovery and complete genome sequencing of a virus from symptomless radish seedlings, classifiable as a novel member of the genus Alphapartitivirus, family Partitiviridae. Total RNA extracted from germinating seedlings was sequenced using Illumina technology. Bioinformatic analysis of the RNA-seq data revealed two contigs representing the near full-length genomic sequences of two genomic RNAs representing a new virus. Analysis of the genome sequence (excluding the polyA tail, RNA1: 1976 nt and RNA2: 1751 nt, respectively) showed a genomic organization typical of viruses classed within the Partitiviridae, with each genomic RNA encoding a single open reading frame (ORF). Phylogenetic analysis of the RNA dependent RNA polymerase (RNA1 ORF) and of the capsid protein (RNA2 ORF) clearly showed the new virus can be classified within the genus Alphapartitivirus, but sequence divergence establishes it as a new species, for which the name “Raphanus sativus cryptic virus 4” is proposed.

  • Complete genome sequence of a phage hyperparasite of Candidatus
           Xenohaliotis californiensis (Rickettsiales) – a pathogen of Haliotis spp

      Pages: 1101 - 1104
      Abstract: Bacteriophages are recognized as major mortality agents of microbes, among them intracellular marine rickettsiales-like bacteria. Recently, a phage hyperparasite of Candidatus Xenohaliotis californiensis (CXc) has been described. This bacterium is considered the causal agent of Withering Syndrome (WS) which is a chronic and potentially lethal disease of abalone species from California, USA and the peninsula of Baja California, Mexico. This hyperparasite which infects CXc could be used as a biocontrol agent for WS. Therefore, it is necessary to obtain genomic information to characterize this phage. In this study, the first complete genome sequence of a novel phage, Xenohaliotis phage (pCXc) was determined. The complete genome of pCXc from red abalone (Haliotis rufescens) is 35,728 bp, while the complete genome of pCXc from yellow abalone (Haliotis corrugata) is 35,736 bp. Both phage genomes consist of double-stranded DNA with a G + C content of 38.9%. In both genomes 33 open reading frames (ORFs) were predicted. Only 10 ORFs encode proteins that have identifiable functional homologues. These 10 ORFs were classified by function, including structural, DNA replication, DNA packaging, nucleotide transport and metabolism, life cycle regulation, recombination and repair, and additional functions. A PCR method for the specific detection of pCXc was developed. This information will help to understand a new group of phages that infect intracellular marine rickettsiales-like bacteria in mollusks.

  • Complete genome sequence and construction of an infectious full-length
           cDNA clone of a German isolate of celery mosaic virus
    • Authors: Hanna Rose; Edgar Maiss
      Pages: 1107 - 1111
      Abstract: The complete genome sequence of a German isolate of celery mosaic virus (CeMV, a potyvirus) from Quedlinburg (DSMZ PV-1003) was determined (MF962880). This represents the second fully sequenced genome of this virus, along with a Californian isolate (HQ676607.1). The positive-sense single-stranded RNA is 10,000 nucleotides in length and shows the typical organization of potyviruses but has a shorter PIPO than CeMV California. In comparison to CeMV isolates from different origins, CeMV-Quedlinburg and isolates from the Netherlands (AF203531.1) and Aschersleben, Germany (AJ271087.1) show a NAG instead of DAG in the region of the coat protein responsible for aphid transmission. In this study the first infectious full-length clone of celery mosaic virus was obtained and the infectivity confirmed by Rhizobium radiobacter infiltration of Apium species.

  • The complete genome sequence of HetPV20-an1, an alphapartitivirus
           infecting the conifer-pathogenic fungus Heterobasidion annosum
    • Authors: Eeva J. Vainio
      Pages: 1113 - 1116
      Abstract: Root rot fungi of the genus Heterobasidion are highly destructive conifer pathogens in the northern Boreal forest region. This report describes the complete genome sequence of Heterobasidion partitivirus 20 infecting a Finnish strain of Heterobasidion annosum. The bisegmented dsRNA genome of HetPV20-an1 encodes a predicted RNA-dependent RNA polymerase of 605 amino acids (aa) and a capsid protein of 536 aa. Based on sequence similarity and phylogenetic analysis, this virus is a new member of the genus Alphapartitivirus. HetPV20-an1 shares ~65% RdRP aa sequence identity with the most similar virus strain, Rosellinia necatrix partitivirus 2, whereas the CP of HetPV20-an1 is most similar to that of rose partitivirus with ~27% overall aa sequence identity. HetPV20-an1 is only distantly related to previously known partitiviruses of Heterobasidion species and shares ~29% RdRP aa sequence identity and ~16% CP aa sequence identity with Heterobasidion partitivirus 1 from H. abietinum.

  • Recognition of six additional cystoviruses: Pseudomonas virus phi6 is no
           longer the sole species of the family Cystoviridae
    • Authors: Sari Mäntynen; Lotta-Riina Sundberg; Minna M. Poranen
      Pages: 1117 - 1124
      Abstract: Cystoviridae is a family of bacterial viruses (bacteriophages) with a tri-segmented dsRNA genome. It includes a single genus Cystovirus, which has presently only one recognised virus species, Pseudomonas virus phi6. However, a large number of additional dsRNA phages have been isolated from various environmental samples, indicating that such viruses are more widespread and abundant than previously recognised. Six of the additional dsRNA phage isolates (Pseudomonas phages phi8, phi12, phi13, phi2954, phiNN and phiYY) have been fully sequenced. They all infect Pseudomonas species, primarily plant pathogenic Pseudomonas syringae strains. Due to the notable genetic and structural similarities with Pseudomonas phage phi6, we propose that these viruses should be included into the Cystovirus genus (and consequently into the Cystoviridae family). Here, we present an updated taxonomy of the family Cystoviridae and give a short overview of the properties of the type member phi6 as well as the putative new members of the family.
