  • Prevalence of S gene mutations within the major hydrophilic region of
           hepatitis B virus in patients in Dongguan, southern China
    • Authors: Siping Li; Mingyu Xie; Wenrui Li; Qi Peng; Baimao Zhong; Xiaomei Lu; Qiang Ma
      Pages: 2949 - 2957
      Abstract: Abstract HBsAg point mutations within the major hydrophilic region (MHR) have frequently been reported to be associated with diagnostic failure, vaccine escape and immunotherapy escape. However, the prevalence of escape mutations in chronic hepatitis B (CHB) patients has not been systematically studied in patients from southern China within the past decade. This study aimed to determine the prevalence of escape mutations within the MHR of hepatitis B virus in patients in Dongguan, southern China. Between June 2015 and May 2016, 391 patients who were chronically infected with HBV were enrolled in the study, including 240 patients with the genotype B strain and 151 with the genotype C strain. The most frequent mutated position was s126 (4.3%), followed by s100 (3.3%), s101 (2.8%), s133 (2.8%), s145 (2.3%), s120 (2.0%) and s129 (1.8%). Furthermore, the mutations sY100C, sQ101R/K, sS114A, sP120T, sT/I126A/N/S, sQ129R, sM133L/T/S and sG145R/A were prevalent in at least one genotype, with a frequency higher than 1%, which indicated that these mutations were relatively common. In addition, sQ101K/R was found only in genotype C isolates (P < 0.05), and sT126A was only discovered in genotype B isolates (P = 0.047), indicating that such mutations were genotype-associated mutations. Notably, combinations of escape mutations within the MHR were also frequently discovered in genotypes B (5.0%) and C (6.6%), with no significant difference (P = 0.498). These results indicated that we should increase the surveillance HBsAg mutations among HBV-infected patients in China.

  • Serological, molecular and clinical correlates of dengue from a tertiary
           care centre in Chennai, India
    • Authors: Vigna Seshan; Gopalsamy Sarangan; Khaleefathullah Sheriff; Kaveri Krishnasamy; Gunasekaran Palani; Padma Srikanth
      Pages: 2983 - 2988
      Abstract: Abstract Dengue disease is caused by dengue viruses 1-4 and has been ranked by the World Health Organisation (WHO) as the fastest spreading vector-borne viral disease. Dengue is often underreported and misdiagnosed due to a wide spectrum of clinical manifestations. Diagnosis of dengue is based on clinical case definitions and laboratory methods. Newer case definitions of dengue have been formulated by clinical studies in order to improve case detection. Owing to its epidemic potential, mortality and morbidity, there is a need for a rapid and accurate diagnostic assay for dengue in order to help the clinician in the early detection of cases and to prevent disease progression. A duplex real time PCR targeting the 3’UTR region for rapid and simultaneous detection of all dengue viruses serotypes (1-4) was standardized based on published literature. About 150 patients with acute undifferentiated febrile illness classified based on the 2009 WHO dengue case definition were tested using the duplex real time dengue PCR. Sequencing based PCR was performed on selected PCR positive samples for partial nucleotide sequence of the CprM gene and a phylogenetic tree was constructed. Statistical analysis was done using the MedCalc software. Out of the 126 patients classified as dengue disease positive, according to the 2009 WHO dengue case definition, 54% had “probable dengue”, 43% had “dengue with warning signs” and 3% had “severe dengue”. The performance of the duplex real time PCR was assessed among the various clinical groups of dengue and it was found that in the “dengue with warning signs group” PCR had a positive predictive value of 85.29% (range - 68.94% to 95.05%) when compared with dengue NS1 ELISA. The average time for PCR positivity was found to be four days from the onset of illness. The cycling threshold values obtained from real time PCR were used as a semi quantitative measure of viremia. Accordingly, there was a relatively low CT value among the “warning signs dengue group” when compared to the “probable dengue group”. The use of the duplex PCR is suggested in the early diagnosis of dengue, especially in the ‘warning signs’ group of patients as they showed a higher positivity rate. Also, the use of the resultant CT value as a semi-quantitative measure of viremia will assist the clinician in early diagnosis and prevention of disease development.

  • An immuno-chromatographic lateral flow assay (LFA) for rapid on-the-farm
           detection of classical swine fever virus (CSFV)
    • Authors: Rathnapraba Sambandam; Raja Angamuthu; Vijayarani Kanagaraj; Kumanan Kathaperumal; Shubhada K. Chothe; Ruth H. Nissly; Rhiannon M. Barry; Bhushan M. Jayarao; Suresh V. Kuchipudi

      Abstract: Abstract Classical swine fever (CSF) is a highly contagious and potentially fatal disease of domestic pigs. Classical swine fever is routinely diagnosed by clinical signs, serology, detection of CSF virus (CSFV) nucleic acid by PCR and virus isolation. Most of the current CSF diagnostic methods are expensive and have an extended turnaround time. In the majority of the CSF endemic countries, lack of easy access to diagnostic facilities is a major problem for swine producers trying to obtain early diagnosis and often results in the entire herd being infected. The acute form of CSF can show non-specific signs of illness, leaving CSF often undiagnosed. Hence there is an urgent need for a rapid and reliable pen side diagnostic assay for the better detection and control of this economically important disease of swine. We developed an immuno-chromatographic lateral flow assay (LFA) for on the farm detection of CSFV. A CSFV isolate [CSFV/AP/TRP2/2009 (TS2)] of genotype 1.1 was used for the production of monoclonal antibodies (mAbs) for the LFA’s development. The virus detection level of the LFA device was 36.8 TCID50/ml of CSFV. The sensitivity and specificity of LFA in comparison with PCR were 80.36% and 87.10%, respectively. The positive and negative predictive values of the LFA device were 91.84% and 87.10%, respectively. In conclusion, the CSFV-LFA is a reliable and convenient resource for preliminary on the farm detection of classic swine fever.

  • Was Kaposi’s sarcoma-associated herpesvirus introduced into China via
           the ancient Silk Road' An evolutionary perspective
    • Authors: Zhenqiu Liu; Qiwen Fang; Jialu Zuo; Veenu Minhas; Charles Wood; Na He; Tiejun Zhang
      Pages: 3061 - 3068
      Abstract: Abstract Kaposi’s sarcoma-associated herpesvirus (KSHV) has become widely dispersed worldwide since it was first reported in 1994, but the seroprevalence of KSHV varies geographically. KSHV is relatively ubiquitous in Mediterranean areas and the Xinjiang Uygur Autonomous Region, China. The origin of KSHV has long been puzzling. In the present study, we collected and analysed 154 KSHV ORF-K1 sequences obtained from samples originating from Xinjiang, Italy, Greece, Iran and southern Siberia using Bayesian evolutionary analysis in BEAST to test the hypothesis that KSHV was introduced into Xinjiang via the ancient Silk Road. According to the phylogenetic analysis, 72 sequences were subtype A and 82 subtype C, with C2 (n = 56) being the predominant subtype. The times to the most recent common ancestors (tMRCAs) of KSHV were 29,872 years (95% highest probability density [HPD], 26,851-32,760 years) for all analysed sequences and 2037 years (95% HPD, 1843-2229 years) for Xinjiang sequences in particular. The tMRCA of Xinjiang KSHV was exactly matched with the time period of the ancient Silk Road approximately two thousand years ago. This route began in Chang’an, the capital of the Han dynasty of China, and crossed Central Asia, ending in the Roman Empire. The evolution rate of KSHV was slow, with 3.44 × 10−6 substitutions per site per year (95% HPD, 2.26 × 10−6 to 4.71 × 10−6), although 11 codons were discovered to be under positive selection pressure. The geographic distances from Italy to Iran and Xinjiang are more than 4000 and 7000 kilometres, respectively, but no explicit relationship between genetic distance and geographic distance was detected.

  • Virulent strain of African swine fever virus eclipses its attenuated
           derivative after challenge
    • Authors: Ilya Titov; Galina Burmakina; Yuriy Morgunov; Sergey Morgunov; Andrey Koltsov; Alexander Malogolovkin; Denis Kolbasov
      Pages: 3081 - 3088
      Abstract: Abstract African swine fever (ASF) is one of the most devastating diseases affecting the swine industry worldwide. No effective vaccine is currently available for disease prevention and control. Although live attenuated vaccines (LAV) have demonstrated great potential for immunizing against homologous strains of African swine fever virus (ASFV), adverse reactions from LAV remain a concern. Here, by using a homologous ASFV Congo strain system, we show passage-attenuated Congo LAV to induce an efficient protective immune response against challenge with the virulent parental Congo strain. Notably, only the parental challenge Congo strain was identified in blood and organs of recovered pigs through B602L gene PCR, long-range PCR, nucleotide sequencing and virus isolation. Thus, despite the great protective potential of homologous attenuated ASFV strain, the challenge Congo strain can persist for weeks in recovered pigs and a recrudescence of virulent virus at late time post-challenge may occur.

  • Genome dynamics and evolution of codon usage patterns in shrimp viruses
    • Authors: Anuj Tyagi; B. T. Naveen Kumar; Niraj K. Singh
      Pages: 3137 - 3142
      Abstract: Abstract We analysed the genomes and codon usage patterns of seven small (DNA and RNA) shrimp viruses. Effective number of codon (ENC) values indicated moderate (35 < ENC < 50) codon usage bias in shrimp viruses. Correlation analysis between GC compositions at non-synonymous codon and synonymous codon positions (GC1, 2 and GC3) as well as GC3 versus ENC curves indicated varying influences of mutational pressure on codon usage. The presence of deoptimized codons and host-antagonistic codon usage trends in shrimp viruses suggested the adaptation of a slow replication strategy by these viruses to avoid host defences. Low CpG frequencies indicated that shrimp viruses have evolved with underrepresentation of CpGs to avoid the host’s immune response.

  • Characterization of an orf virus isolate from an outbreak in Heilongjiang
           province, China
    • Authors: Yongzhong Yu; Qiang Tan; Wenbo Zhao; Xue Zhang; Jinzhu Ma; Zhijun Wu; Zhanbo Zhu; Yudong Cui

      Abstract: Abstract Contagious ecthyma, caused by orf virus (ORFV), is an epitheliotrophic contagious disease with zoonotic implications that mainly affects sheep, goats, wild ruminants, and humans. Recently, a novel ORFV strain, OV/HLJ/04, was successfully isolated from the skin and mucosal lesions of a goat with severe clinical sore mouth symptoms in Heilongjiang province of China. The OV/HLJ/04 isolate was characterized by electron microscopy, serological tests, and experimental reproduction of disease. The purified virions exhibited a typical ovoid shape when observed by electron microscopy. Moreover, experimental reproduction of disease showed that a lamb developed typical clinical signs of contagious ecthyma, such as severe vascular proliferation, when inoculated with the virus. Subsequently, amplification of ORFV011 (B2L) gene fragments of viral DNA by polymerase chain reaction (PCR) and gene sequencing were performed. Phylogenetic analysis of the B2L protein gene revealed that this strain clusters with ORFV strains from epidemic-stricken areas worldwide, including recent mainland China isolates. Analysis using ClustalW MegAlign in DNAStar indicated that OV/HLJ/04 (GenBank: KU523790.1) was genetically closely related to the isolates Gansu (JQ904789), with 99.7% identity; NZ2 (DQ184476), with 97.4% identity; and Xinjiang (KF666560), with 90.6% identity. These results may provide insights into the genotype of the etiological agent responsible for the orf outbreak in Heilongjiang Province.

      Abstract: Abstract The C11-13 strain from the Siberian subtype of tick-borne encephalitis virus (TBEV) was isolated from human brain using pig embryo kidney (PEK), 293, and Neuro-2a cells. Analysis of the complete viral genome of the C11-13 variants during six passages in these cells revealed that the cell-adapted C11-13 variants had multiple amino acid substitutions as compared to TBEV from human brain. Seven out of eight amino acids substitutions in the high-replicating C11-13(PEK) variant mapped to non-structural proteins; 13 out of 14 substitutions in the well-replicating C11-13(293) variant, and all four substitutions in the low-replicating C11-13(Neuro-2a) variant were also localized in non-structural proteins, predominantly in the NS2a (2), NS3 (6) and NS5 (3) proteins. The substitutions NS2a1067 (Asn → Asp), NS2a1168(Leu → Val) in the N-terminus of NS2a and NS31745(His → Gln) in the helicase domain of NS3 were found in all selected variants. We postulate that multiple substitutions in the NS2a, NS3 and NS5 genes play a key role in adaptation of TBEV to different cells.

      Abstract: Abstract Between August and September 2016 pathological samples were collected from sheep and goats following suspected peste des petits ruminants (PPR) outbreaks in western Mongolia. RT-PCR followed by sequencing and phylogenetic analysis of the samples confirmed the presence of a PPR virus belonging to lineage IV. A full genome analysis of the viral RNA from one of the samples revealed a high similarity (99.0-99.5%) with PPR viruses currently circulating in China (2013-2015) indicating a common origin. This is the first genetic characterization of PPR virus in Mongolia and the data generated will have important implications for control and management of the disease in the region.

      Abstract: Abstract Avian influenza A virus (AIV) subtype H9N2 is the most prevalent subtype found in terrestrial poultry throughout Eurasia and has been isolated from poultry outbreaks worldwide. Tracheal tissue specimens from 100 commercial broiler flocks in Afghanistan were collected between 2016 and 2017. After real-time RT-PCR, AI-positive samples were further characterized. A part of the HA gene was amplified using RT-PCR and sequenced. The results of real-time RT-PCR showed that 40 percent of the flocks were AI positive. Phylogenetic studies showed that these H9N2 AIVs grouped within the Eurasian-lineage G1 AIVs and had a correlation with H9N2 AIV circulating in the poultry population of the neighboring countries over the past decade. Analysis of the amino acid sequence of HA revealed that the detected H9N2 viruses possessed molecular profiles suggestive of low pathogenicity and specificity for the avian-like SAα2,3 receptor, demonstrating their specificity for and adaptation to domestic poultry. The results of the current study provide great insights into H9N2 viruses circulating in Afghanistan’s poultry industry and demonstrate the necessity of planning an applied policy aimed at controlling and managing H9N2 infection in Afghan poultry.

      Abstract: Abstract A total of 23 Newcastle disease virus (NDV) isolates from Bangladesh taken between 2010 and 2012 were characterized on the basis of partial F gene sequences. All the isolates belonged to genotype XIII of class II NDV but segregated into three sub-clusters. One sub-cluster with 17 isolates aligned with sub-genotype XIIIc. The other two sub-clusters were phylogenetically distinct from the previously described sub-genotypes XIIIa, XIIIb and XIIIc and could be candidates of new sub-genotypes; however, that needs to be validated through full-length F gene sequence data. The results of the present study suggest that genotype XIII NDVs are under continuing evolution in Bangladesh.

    • Authors: Nayely Heinecke; Jorge Tórtora; Humberto A. Martínez; Víctor D. González-Fernández; Hugo Ramírez
      Pages: 3191 - 3196
      Abstract: Abstract Bovine leukemia virus (BLV) was detected and genotyped in a population of 201 dairy cattle from central Mexico. Using a commercial indirect enzyme-linked immunosorbent assay (iELISA) kit, 118 polymerase chain reaction (PCR)-positive and BLV antibody-positive samples were identified; the concordance between tests was substantial. A phylogenetic study of 27 partial sequences of the env gene gp30 was performed. Four mutations were detected involving the PXXP motif in the cytoplasmic domain of the transmembrane protein. This study provided evidence of the efficacy of PCR for the detection of BLV and demonstrated the presence of genotype 1 BLV in Mexico.

  • Phylogenetic analysis of rabbit haemorrhagic disease virus (RHDV) strains
           isolated in Poland
    • Authors: Andrzej Fitzner; Wieslaw Niedbalski
      Pages: 3197 - 3203
      Abstract: Abstract The aim of this study was to characterise the nucleotide and amino acid sequence of complete genomes (7.5 kb) from RHDV strains isolated in Poland and estimate the genetic variability in different elements of the viral RNA. In addition, the sequence of Polish RHDV isolates isolated from 1988-2015 was compared with the sequences of other European RHDV, including the RHDVa and RHDV2/RHDVb subtypes. The complete sequence was developed by the compilation of partial nucleotide sequences. This sequence consisted of approximately 7428 nucleotides. For comparison of nucleotide sequences and the development of phylogenetic trees of Polish RHDV isolates and reference RHDV strains representing the main phylogenetic groups of classical RHDV, RHDVa and RHDV2 as well as the non-pathogenic rabbit lagovirus RCV, the BLAST software with blastn and MEGA6 with neighbour-joining method was applied. The complete nucleotide sequence of Polish isolates of RHDV has also been entered into GenBank. For comparative analysis, nineteen complete sequences representing the main RHDV genetic types available in GenBank were used. The results of phylogenetic analysis of Polish RHDV strains reveals the presence of three classical RHDV genogroups (G2, G4 and G5) and an RHDVa variant (G6). The oldest RHDV isolates (KGM 1988, PD 1989 and MAL 1994) belong to genogroup G2. It can be assumed that the elimination of these strains from the environment probably occurred at the turn of 1994 and 1995. Genogroup G2 was replaced by the phylogenetically younger BLA 1994 and OPO 2004 strains from genogroup G4, which probably originated from the G3 lineage, represented by the Italian strains BS89. The last representatives of classical RHDV in Poland are isolates GSK 1988 and ZD0 2000 from genogroup G5. A single clade contains the Polish RHDV strains from 2004-2015 (GRZ 2004, KRY 2004, L145 2004, W147 2005, SKO 2013, GLE 2013, RED1 2013, STR 2012, STR2 2013, STR 2014, BIE 2015) identified as RHDVa, which clustered into genogroup G6, as represented by the RHDV strain Triptis 1996. All recent isolated RHDV isolates belong exclusively to RHDVa and no RHDV2 was diagnosed in Poland.

  • In vitro study of Zika virus infection in boar semen

      Pages: 3209 - 3213
      Abstract: Abstract Zika virus (ZIKV) is an important arbovirus that is capable of directly infecting neuronal cells. Infection can cause microcephaly in fetuses and Guillain–Barré syndrome in adults. Recent epidemiological studies have shown that ZIKV is sexually transmitted, especially from infected males to uninfected females. This study aimed to investigate the transmission pattern of ZIKV in semen using boar semen. Experiments were performed ex vivo using semen from healthy boar. The samples were infected with ZIKV, and viral RNA was detected and cell morphology was examined at different time points postinfection. ZIKV infection was confirmed by transmission electron microscopy. Viral RNA levels were found to markedly decrease as the time postinfection increased, without any evidence of virus replication. The sperm showed no significant changes in morphology. Transmission electron microscopy revealed the presence of virus-free sperm, suggesting that ZIKV cannot replicate in boar semen. We suggest three possible reasons underlying this phenomenon. First, the spermatozoa of boar might not be the target of ZIKV associated with sexual transmission. Second, the effect of the external environment on spermatozoa may affect ZIKV replication. Third, ZIKV may not be tropic for spermatozoa. This ex vivo study might be used as a platform to study the association of sexual transmission with ZIKV in other longer-lasting cells, such as Leydig or Sertoli cells.

  • Full genome sequence of jujube mosaic-associated virus, a new member of
           the family Caulimoviridae
    • Authors: Kaitong Du; Sijia Liu; Zhaorong Chen; Zaifeng Fan; He Wang; Guozhong Tian; Tao Zhou
      Pages: 3221 - 3224
      Abstract: Abstract We report a new circular DNA virus identified from a Chinese jujube tree showing mosaic-like symptoms. The genome of this virus is 7194 bp in length and contains five putative open reading frames (ORFs), all on the plus-strand of the genome. The genomic organization, primer binding sites and the sizes of the ORFs were similar to those reported for other badnaviruses (family Caulimoviridae), except for ORF3, which was split into ORF3a and ORF3b with a 70-nt intergenic region. Furthermore, this new virus shares low nucleotide sequence identity (<50%) with other members of the family Caulimoviridae. Consequently, we propose this virus as a new member of the family Caulimoviridae and refer to it as jujube mosaic-associated virus (JuMaV).

      Abstract: Abstract Papillomaviruses are a diverse group of viruses that are known to infect a wide range of animal species. Bovine papillomaviruses (BPVs) are divided into at least 21 genotypes (BPV1 to BPV21),  with most BPV isolates/strains described to date belonging to one of four genera, including Deltapapillomavirus, Xipapillomavirus, Epsilonpapillomavirus and Dyoxipapillomavirus. Here, we describe the identification and genetic characterization of a new BPV type in the genus Dyokappapapillomavirus. A farm in the state of New York, USA, reported chronic cases of vulvovaginitis in Holstein cows in 2016. Biopsies and/or swab samples collected from the vaginal mucosa were subjected to diagnostic investigation. Conventional diagnostic assays yielded negative results, and vaginal swab samples were subjected to viral metagenomic sequencing. Notably, BLAST searches revealed a papillomavirus genome with 7480 bp in length (67% nt sequence identity to BPV16). Additionally, phylogenetic analysis of the L1 gene of the papillomavirus identified here (tentatively named BPV22) revealed that it clusters with members of the genus Dyokappapapillomavirus. Interestingly, the recently identified BPV16, which was detected in fibropapilloma lesions in cattle also clusters within the Dyokappapapillomavirus group. Each virus, however, forms a separate branch in the phylogenetic tree. These results indicate that the putative BPV22 represents the second BPV within the genus Dyokappapapillomavirus.

  • Complete genome sequence of a Capsicum chlorosis virus in China and the
           structural variation and evolutionary origin of its S RNA intergenic
           region
    • Authors: Ying Huang; Hao Hong; Xiao-Hui Zhao; Jia Li; Xiao-Rong Tao
      Pages: 3229 - 3232
      Abstract: Abstract The complete genome sequence of a Capsicum chlorosis virus from China (CaCV-Hainan) was determined. The tripartite genome of CaCV-Hainan consists of small (S), medium (M), and large (L) RNAs of 3629, 4859, and 8912 nucleotides (nt), respectively. The S and M RNAs contain intergenic regions (IGRs) of 1348 and 462 nt, respectively. Strikingly, sequence comparisons among CaCV isolates revealed that the S RNA IGR of CaCV-Hainan derived from the CaCV-Qld-3432 Australia isolate through deletion of two stretches of 25- and 325-nt sequences within the S RNA IGR of CaCV-Qld-3432. Moreover, the S RNA IGR of CaCV-Hainan was inserted with two stretches of 10- and 20-nt sequences of an unknown origin. The S RNA IGR of CaCV-Ph from Taiwan and CaCV-NRA from Thailand also derived from the CaCV-Qld-3432 through deletion of 218-nt sequences. Our findings provide valuable new insight into the structural variations and evolutionary origin of CaCV IGRs.

      Pages: 3243 - 3245
      Abstract: Abstract The complete genome sequence of Kurlavirus, a new member of the family Marseilleviridae is reported. The Kurlavirus genome was found to encode a remarkable complement of genes homologous to those of other members of the family Marseilleviridae. Interestingly, the Kurlavirus genome contains 71 fewer ORFs than that of Marseillevirus, even though their genome sizes are comparable.

  • Complete genome sequence of rice virus A, a new member of the family
           Tombusviridae

      Abstract: Abstract An evaluation of the virus population in rice plants using next-generation sequencing technologies resulted in the discovery of a new RNA virus, tentatively named rice virus A (RVA). The complete RVA genome sequence was determined and analyzed, revealing a genome organization resembling that of viruses classified in the genera Aureusvirus, Tombusvirus and Zeavirus within the family Tombusviridae. With 4,832 nucleotides, the RVA genome may be the largest monopartite genome sequenced to date in the family Tombusviridae. The 453-amino acid RVA coat protein shares the highest identity with the gp3 protein of an unclassified carascovirus, SF1 (GenBank accession no. KF510027) isolated from San Francisco wastewater, rather than the coat protein of any known member of the family Tombusviridae. These novel characteristics represent a significant divergence from the genomes of viruses belonging to the sixteen existing genera of the family Tombusviridae, demonstrating that RVA is likely a new family member.
