Abstract
Enterovirus, like the majority of RNA viruses, evolves to survive the changeable environments by a variety of strategies. Here, we showed that HY12 virus evolved to alter its characteristics and pathogenicity by employing a non-synonymous mutation. Analyses of 5'UTR, VP1 and VP2 gene sequences revealed the existence of HY12 virus in an array of mutants defined as quasispecies. The determination of diversity and complexity showed that the mutation rate and complexity of HY12 virus quasispecies increased, while the proportion of HY12 VP1 and VP2 consensus (master) sequences decreased with increasing passages. Synonymous mutation and non-synonymous mutation analysis displayed a positive selection for HY12 quasispecies evolution. A comparison of HY12 virus in different passages demonstrated that HY12 virus altered its characteristic, phenotype, and pathogenicity via non-synonymous mutation. These findings revealed the evolution pattern for HY12 virus, and the alteration of HY12 virus characteristics and pathogenicity by mutation.

Abstract
Until recently X-ray crystallography has been the standard technique for virus structure determinations. Available X-ray sources have continuously improved over the decades, leading to the realization of X-ray free-electron lasers (XFELs). They provide high-intensity femtosecond X-ray pulses, which allow for new kinds of experiments by making use of the diffraction-before-destruction principle. By overcoming classical dose constraints, they at least in principle allow researchers to perform X-ray virus structure determination for single particles at room temperature. Simultaneously, the availability of XFELs led to the development of the method of serial femtosecond crystallography, where a crystal structure is determined from the measurement of hundreds to thousands of microcrystals. In the case of virus crystallography this method does not require freezing of the crystals and allows researchers to perform experiments under non-equilibrium conditions (e.g., by laser-induced temperature jumps or rapid chemical mixing), which is currently not possible with electron microscopy.

Molecular Identification of Enteroviruses from Cattle and Goat Feces and Environment in Thailand. Appl Environ Microbiol 2019; 85:AEM.02420-18. [PMID: 30552188 DOI: 10.1128/aem.02420-18] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2018] [Accepted: 12/07/2018] [Indexed: 12/29/2022] Open
Abstract
The identification and characterization of viruses of the genus Enterovirus in healthy and infected livestock, including cattle and goats, have been increasing. Enterovirus E (EV-E) and Enterovirus F (EV-F) are commonly found in cattle, whereas Enterovirus G (EV-G) is found in goats. In this study, molecular and phylogenetic analyses were performed to determine the prevalence of EVs in cattle and goat feces from Kanchanaburi Province, Thailand. The presence of EVs in water samples and the feces of other animals collected from the areas surrounding cattle and goat farms was also investigated. By use of 5'-untranslated region (5' UTR) real-time reverse transcription-PCR (RT-PCR), EVs were detected in 39.5% of cattle samples, 47% of goat samples, 35.3% of water samples, and one pool of chicken feces. Phylogenetic analysis revealed the presence of EV-E and EV-F in cattle, EV-E and EV-G in goats, and EV-F in water samples and chicken feces. Analysis of enteroviral VP1 sequences from cattle revealed that the EV-E genotypes circulating in the study region were EV-E1, with a possible new genotype that is closely related to EV-E2. Analysis of enteroviral VP1 sequences from goats suggested the circulation of EV-G5 and a possible new genotype that is closely related to EV-G20. Sequence analyses also suggested that although the VP1 sequences from goats were closely related to those of EV-G, which were considered porcine enterovirus sequences, their 5' UTRs form a separated cluster with sequences of sheep and goat origin, suggesting a new classification of the ovine/caprine-specific enterovirus group.IMPORTANCE Possible new EV-E and EV-G genotypes were identified for EVs detected in this study. The EV-E viruses were also successfully isolated from MDBK cells. The goat EV sequence analysis suggested the presence of an ovine/caprine-specific EV group that is different from EV-G of porcine origin. The significance of our research is that it identifies and characterizes possible novel EVs, thereby indicating that enteroviruses in animals are continually evolving. The facts that enteroviruses can persist in the environment, contaminate it for long periods, and be transmitted between animals raise serious concerns regarding this group of viruses as emerging livestock pathogens.

Construction and evaluation of HA-epitope-tag introduction onto the VP1 structural protein of a novel HY12 enterovirus. Virology 2018; 525:106-116.

Abstract
In this study, we investigated the feasibility of using enterovirus HY12 as a vector to express an exogenous hemagglutinin (HA)-epitope tag onto the HY12-encoded VP1 protein via a reverse genetic system. Characteristics of recombinant (r) HY12-VP1-HA marker virus were determined by immunoperoxidase monolayer assay, western blot, electron microscopy, and serum-neutralisation assay. Sequence analysis demonstrated that the marker virus stably maintained the HA-epitope-tag in MDBK cells, with no changes in viral morphological features observed relative to those of the parental rHY12 virus. Furthermore, detection by immunofluorescence assay revealed the expression of HA-epitope tag and VP2 protein, which distinguish the marker virus from parental rHY12 virus. In addition, neonatal mice infected with the recombinant marker virus showed various microscopic pathological lesions and generated anti-HY12 virus and -HA-epitope-tag antibodies. These results indicated that the recombinant marker virus represented a valuable platform to promote the development of novel genetic vaccines.

Abstract
We report a method for serial X-ray crystallography at X-ray free-electron lasers (XFELs), which allows for full use of the current 120-Hz repetition rate of the Linear Coherent Light Source (LCLS). Using a micropatterned silicon chip in combination with the high-speed Roadrunner goniometer for sample delivery, we were able to determine the crystal structures of the picornavirus bovine enterovirus 2 (BEV2) and the cytoplasmic polyhedrosis virus type 18 polyhedrin, with total data collection times of less than 14 and 10 min, respectively. Our method requires only micrograms of sample and should therefore broaden the applicability of serial femtosecond crystallography to challenging projects for which only limited sample amounts are available. By synchronizing the sample exchange to the XFEL repetition rate, our method allows for most efficient use of the limited beam time available at XFELs and should enable a substantial increase in sample throughput at these facilities.

Identification of a novel bovine enterovirus possessing highly divergent amino acid sequences in capsid protein. BMC Microbiol 2017; 17:18. [PMID: 28095784 PMCID: PMC5240211 DOI: 10.1186/s12866-016-0923-0] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2016] [Accepted: 12/28/2016] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Bovine enterovirus (BEV) belongs to the species Enterovirus E or F, genus Enterovirus and family Picornaviridae. Although numerous studies have identified BEVs in the feces of cattle with diarrhea, the pathogenicity of BEVs remains unclear. Previously, we reported the detection of novel kobu-like virus in calf feces, by metagenomics analysis. In the present study, we identified a novel BEV in diarrheal feces collected for that survey. Complete genome sequences were determined by deep sequencing in feces. Secondary RNA structure analysis of the 5' untranslated region (UTR), phylogenetic tree construction and pairwise identity analysis were conducted. RESULTS The complete genome sequences of BEV were genetically distant from other EVs and the VP1 coding region contained novel and unique amino acid sequences. We named this strain as BEV AN12/Bos taurus/JPN/2014 (referred to as BEV-AN12). According to genome analysis, the genome length of this virus is 7414 nucleotides excluding the poly (A) tail and its genome consists of a 5'UTR, open reading frame encoding a single polyprotein, and 3'UTR. The results of secondary RNA structure analysis showed that in the 5'UTR, BEV-AN12 had an additional clover leaf structure and small stem loop structure, similarly to other BEVs. In pairwise identity analysis, BEV-AN12 showed high amino acid (aa) identities to Enterovirus F in the polyprotein, P2 and P3 regions (aa identity ≥82.4%). Therefore, BEV-AN12 is closely related to Enterovirus F. However, aa sequences in the capsid protein regions, particularly the VP1 encoding region, showed significantly low aa identity to other viruses in genus Enterovirus (VP1 aa identity ≤58.6%). In addition, BEV-AN12 branched separately from Enterovirus E and F in phylogenetic trees based on the aa sequences of P1 and VP1, although it clustered with Enterovirus F in trees based on sequences in the P2 and P3 genome region. CONCLUSIONS We identified novel BEV possessing highly divergent aa sequences in the VP1 coding region in Japan. According to species definition, we proposed naming this strain as "Enterovirus K", which is a novel species within genus Enterovirus. Further genomic studies are needed to understand the pathogenicity of BEVs.

Abstract
Background Bovine enteroviruses (BEV) are members of the genus Enterovirus in the family Picornaviridae. They are predominantly isolated from cattle feces, but also are detected in feces of other animals, including goats and deer. These viruses are found in apparently healthy animals, as well as in animals with clinical signs and several studies reported recently suggest a potential role of BEV in causing disease in animals. In this study, we surveyed the presence of BEV in domestic and wild animals in Thailand, and assessed their genetic variability. Methods Viral RNA was extracted from fecal samples of cattle, domestic goats, Indian bison (gaurs), and deer. The 5’ untranslated region (5’UTR) was amplified by nested reverse transcription-polymerase chain reaction (RT-PCR) with primers specific to BEV 5’UTR. PCR products were sequenced and analyzed phylogenetically using the neighbor-joining algorithm to observe genetic variations in regions of the bovine and bovine-like enteroviral 5’UTR found in this study. Results BEV and BEV-like sequences were detected in the fecal samples of cattle (40/60, 67 %), gaurs (3/30, 10 %), and goats (11/46, 24 %). Phylogenetic analyses of the partial 5’UTR sequences indicated that different BEV variants (both EV-E and EV-F species) co-circulated in the domestic cattle, whereas the sequences from gaurs and goats clustered according to the animal species, suggesting that these viruses are host species-specific. Conclusions Varieties of BEV and BEV-like 5’UTR sequences were detected in fecal samples from both domestic and wild animals. To our knowledge, this is the first report of the genetic variability of BEV in Thailand.

Abstract
Bovine enterovirus (BEV) was isolated from diarrheic calves in Egypt. Sequencing revealed of BEV/Egypt/2014//KM667941 to have 7417 nucleotides (nt). The organization of nt was typical of the BEV genome including 822 nt in 5′NTR, 6498 nt in ORF, and 97 nt in 3′NTR. Phylogenetic analysis revealed clustering of BEV/Egypt/2014/KM667941 with BEV-F. A specific RT-PCR for BEV was developed to detect this pathogen in cattle.
Enteroviruses belong to the Picornaviridae family and infect a wide range of mammals including cattle. Bovine enterovirus (BEV) has recently been reclassified into E and F serotypes. BEV was first isolated in Egypt in 1966 although it has been known in other countries since the 1950s. In this study, BEV-F2 was isolated from calves with severe diarrhea and the isolated viruses were subjected to molecular characterization. Illumina sequencing of one of the isolates revealed the presence of a complete BEV-F genome sequence. The phylogenetic analysis revealed nucleotide substitutions along the genome in comparison with other known strains of BEV-F (HQ663846, AY508697 and DQ092795). Two primer sets were designed from the 3D and 5′NTR regions and used for the examination of the remaining isolates, which were confirmed to be of the BEV-F2 serotype. The availability of the complete genome sequence of this virus adds to the sequence database of the members of Picornaviridae and should be useful in future molecular studies of BEV.

On the basis of generation of an infectious cDNA clone for the BHM26 strain of bovine enterovirus cluster B (BEV-B), 22 sites on different loops of the BHM26 capsid were selected according to an alignment of its sequence with the structural motifs of BEV-A strain VG-5-27 for insertion of the foot-and-mouth disease virus (FMDV) type O-conserved neutralizing epitope 8E8. Two recombinant viruses, rBEV-A1 and rBEV-DE, in which the FMDV epitope was inserted into the VP1 B-C or D-E loops, were rescued by transfection of BHK-21 cells with the in vitro-transcribed RNA of the recombinant BHM26 genome-length cDNA constructs. The two epitope-inserted viruses were genetically stable and exhibited growth properties similar to those of their parental virus in BHK-21 and IBRS-2 cells, which are susceptible to both BEV and FMDV. However, the two recombinant BEVs (rBEVs) had a significantly lower growth titre than those of the parental virus BHM26 in MDBK and Marc145 cells, which are susceptible to BEV but not to FMDV. These results indicated that insertion of the FMDV epitope into the VP1 B-C or D-E loops of the BEV particle altered the replication properties of BEV. In addition, the two rBEVs were sensitive to neutralization by the FMDV type O-specific mAb 8E8, and anti-FMDV IgG antibodies were induced in mice by intramuscular inoculation with the rBEV-A1 and rBEV-DE viruses. Our results demonstrate that the VP1 B-C and D-E loops of the BEV-B particle can effectively display a foreign epitope, making this an attractive approach for the design of BEV-vectored and epitope-based vaccines.

Abstract
A cytopathic virus was isolated using Madin-Darby bovine kidney (MDBK) cells from lung tissue of alpaca that died of a severe respiratory infection. To identify the virus, the infected cell culture supernatant was enriched for virus particles and a generic, PCR-based method was used to amplify potential viral sequences. Genomic sequence data of the alpaca isolate was obtained and compared with sequences of known viruses. The new alpaca virus sequence was most similar to recently designated Enterovirus species F, previously bovine enterovirus (BEVs), viruses that are globally prevalent in cattle, although they appear not to cause significant disease. Because bovine enteroviruses have not been previously reported in U.S. alpaca, we suspect that this type of infection is fairly rare, and in this case appeared not to spread beyond the original outbreak. The capsid sequence of the detected virus had greatest homology to Enterovirus F type 1 (indicating that the virus should be considered a member of serotype 1), but the virus had greater homology in 2A protease sequence to type 3, suggesting that it may have been a recombinant. Identifying pathogens that infect a new host species for the first time can be challenging. As the disease in a new host species may be quite different from that in the original or natural host, the pathogen may not be suspected based on the clinical presentation, delaying diagnosis. Although this virus replicated in MDBK cells, existing standard culture and molecular methods could not identify it. In this case, a highly sensitive generic PCR-based pathogen-detection method was used to identify this pathogen.

Abstract
The pathogenesis and virulence of Bovine enterovirus-1 (BEV-1) in cattle is largely unknown. Reports concerning its virulence suggest that there might be an association between BEV-1 infections and a range of diseases in cattle that vary from respiratory to enteric to reproductive disease and infertility. In the current study, the pathogenesis associated with acute infection of BEV-1 in calves experimentally inoculated with the Oklahoma isolate of BEV-1 was described. Although interpretation of the study was limited by lack of an effective control group, results suggest that an association between inoculation of BEV-1, virus localization, and the potential development of lesions in the brain and heart probably exists. In the experiment, BEV-1 virus localized to the terminal ileum, ileocecal and cecocolonic junctions, spiral colon, and ileocecal lymph nodes; BEV-1 virus was detected in the cytoplasm of enterocytes, lamina propria macrophages, endothelium, neurons of the submucosal and myenteric plexi, and lymphocytes of the submucosal lymphoid tissue. Although no clinical signs were noted following acute infection, BEV-1 was localized in the cerebellar white matter of a calf with encephalitis and in the heart of another calf with coronary arteritis. The current study suggests that the BEV-1 isolate is infectious to young calves and that BEV-1 potentially can have a similar pathogenesis to that observed in natural or experimental enterovirus infections in other species.

Abstract
One 2-year-old, 7.5 months pregnant Aberdeen Angus out of a herd of 100 apparently healthy cows, died within 10 hours of hospitalization. At necropsy, multiple foci of mucosal hemorrhage and ulceration were observed in the spiral colon and cecum. Virus isolation from intestinal lesions yielded a cytopathic virus, which was revealed by electron microscopy to be an approximately 27 nm, nonenveloped virus. Further characterization by reverse transcription-polymerase chain reaction (RT-PCR), sequencing of the 5'UTR and partial VP1 coding region, and phylogenetic analysis classified the virus isolate as bovine enterovirus type 1 (BEV-1). No other significant pathogens were detected. This is the first report of BEV-1 isolated in the USA from an animal with fatal enteric disease in more than 20 years. Further investigation is required to determine the prevalence of BEV in North America and to establish the clinical relevance of this understudied virus.

Abstract
Two enteroviruses, designated W1 and W6, were isolated from intestinal contents of Australian brushtail possums (Trichosurus vulpecula) in New Zealand. The genomic sequences of W1 and W6 were 7390 and 7391 nucleotides (nt), respectively. Genetically, possum isolates W1 and W6 were related to bovine enterovirus serotype 2 (BEV-2) strains, especially to the strain PS87/Belfast, based on the capsid protein sequence. However, W1 and W6 formed a clade that was distinct from PS87Belfast based on nucleotide sequences of the 3' and 5'-non-translated region and in the amino acid sequences of 2A, 3C and 3D. Possum isolates W1 and W6 grew more readily in possum kidney cells than in Madin-Darby bovine kidney (MDBK) cells, suggesting that co-evolution of W1 and W6 with possums has made them more adapted to possum cells.

Abstract
Bovine enteroviruses are currently classified into two serotypes within the species Bovine enterovirus (BEV). Comparison of the sequences of six American and eleven German BEV isolates with published BEV sequences revealed the necessity to revise the taxonomy of these viruses. Molecular data indicate that the bovine enteroviruses are composed of two clusters (designated BEV-A and -B) each with two and three geno-/serotypes, respectively. Whereas low amino acid identity of the capsid proteins 1C (VP3) and 1D (VP1) is the main criterion for the discrimination of geno-/serotypes, the BEV clusters, presumably representing species, differ in sequence identity of all viral proteins. In addition, characteristic lengths of (i) the capsid proteins 1B, 1C and 1D, (ii) the 2C protein, and (iii) the 3'-non-translated region are observed. The BEVs can be distinguished from the other enteroviruses by sequence identity and unique features of the 5'-non-translated region, i.e. a conserved second cloverleaf and characteristic RNA structures of the internal ribosome entry site. Phylogenetically, the closest relatives of the bovine enteroviruses are the porcine enteroviruses. Incongruent phylogenies of the 5'-non-translated region, the capsid proteins and the 3D polymerase indicate frequent intraserotypic and interserotypic recombination within the non-capsid and the capsid region of the BEV genome.

Abstract
Animal enteroviruses shed in the feces of infected animals are likely environmental contaminants and thus can be used as indicators of animal fecal pollution. Previous work has demonstrated that bovine enterovirus (BEV) present in bovine feces contaminates waters adjacent to cattle herds and that BEV-like sequences are also present in shellfish and in deer feces from the same geographical area. However, little information is available about the prevalence, molecular epidemiology, and genomic sequence variation of BEV field isolates. Here we describe an optimized highly sensitive real-time reverse transcription-PCR method to detect BEV RNA in biological and environmental samples. A combination of the amplification procedure with a previously described filtration step with electropositive filters allowed us to detect up to 12 BEV RNA molecules per ml of water. The feasibility of using the method to detect BEV in surface waters at a high risk of fecal pollution was confirmed after analysis of water samples obtained from different sources. The method was also used to study the prevalence of BEV in different cattle herds around Spain, and the results revealed that 78% (78 of 100) of the fecal samples were BEV positive. BEV-like sequences were also detected in feces from sheep, goats, and horses. Nucleotide sequence analyses showed that BEV isolates are quite heterogeneous and suggested the presence of species-specific BEV-like variants. Detection of BEV-like sequences may help in the differentiation and characterization of animal sources of contamination.

Abstract
We present a set of programs and a website designed to facilitate protein structure comparison and protein structure modeling efforts. Our protein structure analysis and comparison services use the LGA (local-global alignment) program to search for regions of local similarity and to evaluate the level of structural similarity between compared protein structures. To facilitate the homology-based protein structure modeling process, our AL2TS service translates given sequence–structure alignment data into the standard Protein Data Bank (PDB) atom records (coordinates). For a given sequence of amino acids, the AS2TS (amino acid sequence to tertiary structure) system calculates (e.g. using PSI-BLAST PDB analysis) a list of the closest proteins from the PDB, and then a set of draft 3D models is automatically created. Web services are available at .
