Abstract
Rotavirus A infects many mammalian species, including humans and causes diarrhea and gastrointestinal diseases. The virus also infects various bird species, including chickens, although information of avian rotavirus A (ARVA) infection in chicken populations in Japan is scarce. In this study, we report for the first time the whole-genome sequences of ARVA strains from Japanese chicken populations. The virus strains were inoculated to MA104 cells and cultured viruses were used to obtain the sequences with the MiSeq system, and genetic analysis demonstrated the genotype constellation of G19-P[30]-I11-R6-C6-M7-A16-N6-T8-E10-H8 of the Japanese chicken ARVA isolates. Phylogenetic analyses demonstrated that the VP1, VP2, VP3, VP4, VP7, NSP2, and NSP4 coding gene sequences of the Japanese strains were closer to those of Korean than the European ARVA strains, although such relationship was not clear for other genes. The data suggest that the Japanese ARVA strains and the ones in Korea have genetically close relationship, although the origin is not clear at this point. Further information including the whole-genome sequences of the Korean strains and sequences of other Japanese chicken ARVA strains will be necessary for elucidation of their origin.

Abstract
Introduction Canine mesothelioma is a rare malignant tumor that mostly affects body cavities, such as the pericardial and pleural cavities. Chemotherapy plays a crucial role in the treatment of canine mesotheliomas. We aimed to compare the antitumor effects of single-agent and combination chemotherapeutic agents on patient-derived primary cultures of canine pericardial mesothelioma established in this study. We planned to generate xenograft models for future studies. Material and methods Effusion samples were collected from three dogs with histologically diagnosed pericardial mesothelioma and used for primary culture. Cultured cells were characterized by immunostaining for pan-cytokeratin AE1/AE3, vimentin, Wilms' tumor suppressor gene 1 (WT1), and cytokeratin 5 (CK5). To assess the tumorigenic properties of cells in the effusion and generate a xenograft model, the cell suspension was injected into a severe combined immunodeficient (SCID) mouse either subcutaneously (SC) or intraperitoneally (IP). Lastly, chemosensitivity of established primary cultures against four drugs, doxorubicin, vinorelbine, carboplatin, and gemcitabine, by single-agent treatment as well as combination treatment of carboplatin at a fixed concentration, either 10 or 100 μM, and gemcitabine at different concentrations ranging from 0-1000 μM was assessed by cell viability assay. Results Primary cultures were successfully generated and characterized by dual positivity for AE1/AE3 and vimentin and positive staining for WT-1 and CK5, confirming the mesothelial origin of the cells. In the xenograft models, SC mouse developed a subcutaneous mass, whereas IP mouse developed multiple intraperitoneal nodules. The masses were histopathologically consistent with mesotheliomas. The chemosensitivity assay revealed that carboplatin had the highest anti-tumor effects among the four tested single-agent treatments. Furthermore, carboplatin at 100 μM combined with gemcitabine at clinically relevant doses demonstrated the augmented anti-tumor effects compared to single-agent treatment. Discussion and conclusion Primary cultures and xenograft models generated in this study could be useful tools for in vitro and in vivo studies of canine mesothelioma. Carboplatin is a highly effective chemotherapeutic agent against canine mesothelioma when used as a sole agent and in combination with gemcitabine.

Abstract
The geneLEAD VIII is a fully-automated nucleic acid extraction/quantitative PCR equipment developed by Precision System Science Co. Ltd, (PSS). To take advantage of its capability, we developed a quantitative assay system to measure growth of animal viruses. The system was used to assay one of the Chinese herbal extracts whose anti-malarial activities were previously reported and demonstrated its dose-dependent anti-viral activity against feline infectious peritonitis virus (FIPV), a feline coronavirus causing the fatal diseases in cats, and relatively low cell toxicity. The assay developed in this study is useful to screen antiviral drugs and the anti-FIPV activity of the herbal extract identified have a potential to lead to development of new drugs against FIPV and other coronaviruses, such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Abstract
Abstract
Background
Catheter ablation (RFA) is significantly more effective in terms of arrhythmia recurrence rate than antiarrhythmic medication. For the duration of the procedure, the patient needs to remain motionless on the operation table. General anesthesia (GA) is widely used during atrial fibrillation (AF) ablation in all over the world, however RFA of AF is performed under conscious sedation (CS) in the most centers in Japan.
It remains controversial whether cardiac anesthesiologists are best suited to manage anesthesia in the electrophysiology lab.
Objective
The aim of this study was to report the efficacy and safety of GA during AF ablation.
Methods
297 patients (67.3±11.7 years, 208 men, 128 paroxysmal, mean follow up 443 days±306) with AF undergoing RFA in our department from January 2018 to December 2021 were retrospectively analyzed. 113 assigned to the GA group, 184 patients to the CS group.
The primary efficacy end point was radiofrequency time, ablation index, force time integral. The secondary end points defined AF recurrence and the complications.
Result
There was no difference in the baseline characteristics between the two groups. There was no difference between groups in AF recurrence (22.1% vs. 14.1%, P=0.103) and complications.However, Patients in GA had shorter radiofrequency times (66.9±3.7 minute vs 79.0±2.9 minutes P=0.01)Ablation index (376±18.6 vs 371±22.6 P<0.05), Force time integral (136±22.3 vs 111.4±45.3).
Conclusion
General anesthesia is superior to conscious sedation with shorter radiofrequency times and higher than Force time integral, ablation index. Moreover, it is not inferior in regard to arrhythmia recurrence or complication rates of catheter ablation of atrial fibrillation.

Abstract
Rotavirus C (RVC) is a major cause of diarrhoea in swine, cattle, and humans worldwide. RVC exhibits sequence diversity in all 11 genes, especially in VP4 and VP7, and all segment-based genotyping has been performed similar to rotavirus A. To date, recombination events have been reported in rotavirus A and B. However, there are no reports describing gene recombination of RVC, except for recombination in NSP3 between RVC and rotavirus H. In this study, nine porcine RVC strains identified in Japanese pigs were completely sequenced and analysed together with RVC sequences from the GenBank database. The analyses showed that sequences of the VP4, VP2, and NSP1 of several porcine RVC strains did not branch with any of those of the RVC strains in the GenBank database, suggesting new genotypes. Several homologous recombination events, between or within genotypes, were identified in the VP4, VP7, VP2, NSP1, and NSP3 genes. Of these, nine, one, and one intergenotypic recombination events in the VP4, VP2, and NSP3 genes, respectively, were supported with sufficient statistical values. Although these findings suggest occurrences of the intragenic recombination events in the RVC genome, potential sequence errors and poor sequence assemblies in the databases should be watched with care. The results in this study present data about the important recombination events of the RVCs, which influence evolution of the virus by aiding them to gain genetic diversity and plasticity, although further sequence data will be necessary to obtain more comprehensive understanding of such mechanisms.

Abstract
Malaria, a disease caused by the protozoan parasites Plasmodium spp., is still causing serious problems in endemic regions in the world. Although the WHO recommends artemisinin combination therapies for the treatment of malaria patients, the emergence of artemisinin-resistant parasites has become a serious issue and underscores the need for the development of new antimalarial drugs. On the other hand, new and re-emergences of infectious diseases, such as the influenza pandemic, Ebola virus disease, and COVID-19, are urging the world to develop effective chemotherapeutic agents against the causative viruses, which are not achieved to the desired level yet. In this review article, we describe existing drugs which are active against both Plasmodium spp. and microorganisms including viruses, bacteria, and fungi. We also focus on the current knowledge about the mechanism of actions of these drugs. Our major aims of this article are to describe examples of drugs that kill both Plasmodium parasites and other microbes and to provide valuable information to help find new ideas for developing novel drugs, rather than merely augmenting already existing drug repurposing efforts.

Abstract
Plasmodium falciparum, the most virulent human malaria parasite, causes serious diseases among the infected patients in the world and is particularly important in African regions. Although artemisinin combination therapy is recommended by the WHO for treatment of P. falciparum-malaria, the emergence of artemisinin-resistant parasites has become a serious issue which underscores the importance of sustained efforts to obtain novel chemotherapeutic agents against malaria. As a part of such efforts, thirty-nine herbal extracts from traditional Chinese medicine (TCM) were assayed for their anti-malarial activity using 3D7 strain of P. falciparum. Three herbal supplements appeared to possess higher specific anti-malarial activity than the others. One of them (D3) was separated by two sequential fractionations with reverse-phase (the first step) and normal-phase (the second step) liquid chromatography, in which some fractions resulted in higher specific activities than those of D3 or the previous fractions. Cell toxicity assay was performed with the fractions of the first fractionation and demonstrated no obvious cell toxicity. These results suggest that structure determination of the major compound for the anti-malarial activity in D3 may help the development of more potent chemicals in the future.

Abstract
INTRODUCTION Dogs are known as asymptomatic carriers forCampylobacter jejuni. The number of pet dogs is increasing in Egypt in the last decade. OBJECTIVE This study aimed to investigate the frequency ofC. jejuni infection in dogs and humans, molecular typing of associated virulence genes, and flaA-SVR gene using sequencing. METHODOLOGY 152 unpaired fecal swabs from dogs (n = 72) and humans (80) were examined for the presence of C. jejuni and Campylobacter 23S rRNA, and the pathogenicity genes including mapA genes, virB11, flaA, wlaN, iam, tetO, and aadA genes. Sequencing of the flaA- amplicon was also performed for the representative isolates. RESULTS The isolation rate ofC. jejuni was 20.8 % and 31.2 %, respectively in dogs and humans, and all isolates were tested positive for 23S rRNA and mapA genes. C. jejuni harbor virB11 and wlaN (20 %, 0%), iam (10 %, 20 %), tetO and aadA1 (40 %, both), and flaA (40 %, 20 %) in human and dog strains, respectively. The flaA-SVR sequences revealed high identity between human and dog isolates (94.8 %), but revealed 18 substitutions in the amino acid sequence, and showed that the dog and human C. jejuni were close to strains isolated from human and poultry sources. CONCLUSION this study demonstrated the comparative sequence analysis ofC. jejuni flaA-SVR fragment in dogs and some Egyptians, which indicated a high identity percentage between them. The results suggest that C. jejuni reservoirs dogs is an alarming public health concern and effective hygienic measures are necessary for house-holding pets to prevent C. jejuni zoonosis in Egypt's community.

Abstract
Mammalian orthoreoviruses (MRVs) have been identified in various mammalian species, including humans, bats, and pigs. However, isolation and complete genome sequences of MRVs from wild boars have not yet been reported. In this study, we isolated, sequenced, and analyzed an MRV from a free-living wild boar in Japan using the porcine-sapelovirus-resistant cell line N1380. Complete and empty virus particles were obtained from the N1380 cell culture supernatants, and complete genome sequences were obtained from complete virus particles. Sequence analysis revealed that the isolated MRV, named TY-14, could be classified as MRV3 and had a close genetic relationship to an MRV2 isolate from a lion in a Japanese zoo (L2, L3, and M3 genes) and a human MRV2 isolate from Japan (S2 gene). Phylogenetic analysis showed that TY-14 clustered only with bat MRVs in the M1 phylogenetic tree but formed a cluster with several animal MRVs in the M2 and S3 phylogenetic trees and branched independently in the L1, S1, and S4 phylogenetic trees, suggesting a genetic relationship to viruses of unknown origin. Recombination events were identified in the M2 gene. These results suggest that TY-14 was generated by reassortment and recombination events involving MRVs circulating in Japan, viruses from bats, and other viruses of unknown origin.

Abstract
Abstract
Background
Fractional flow reserve (FFR) is one of most reliable index for the determining the functional severity coronary artery stenosis. Adenosine is the most commonly used agent for maximal hyperaemia. However, adenosine can cause chest discomfort, bronchial hyper-reactivity, and atrioventricular block. The aim of this study is to evaluate the safety and efficacy of intracoronary nicorandil as an alternative hyperaemic agent for FFR.
Methods and results
We enrolled consecutive 82 patients (87 lesions) who underwent FFR measurement in our center from Nov. 2018. We compared three groups; intravenous infusion of adenosine (150 μg/kg/min); and adenosine added intracoronary nicorandil 2mg; and intracoronary nicorandil 4mg. Mean FFR value was 0.83±0.09, 0.82±0.09, 0.82±0.08, There was a strong correlation among three groups (R2>0.9). Mean cyclic change in FFR was 0.026±0.023, 0.019±0.010, 0.016±0.014, respectively, cyclic change was smallest in intracoronary nicorandil 4mg group (vs ATP; p<0.001, vs ATP + nicorandil 2mg; p<0.001). By Wilcoxon test, mean FFR value of nicorandil 4mg was significant lower than ATP (p=0.0021), and equal to ATP + nicorandil 2mg (p=0.98).
Conclusions
Intracoronary nicorandil 4mg is a simple, safe, and effective way to induce steady-state hyperaemia for FFR.

Abstract
In order to study potential pathogenic mechanisms of feline morbillivirus (FeMV) in infected kidney cells, we performed a terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay and an immunofluorescence assay (IFA) with an anti-FeMV P protein antibody on a total of 38 cat kidney tissues, 12 of which were positive for FeMV. Among these samples, we detected significantly larger numbers of apoptotic cells in FeMV-positive tissues than in FeMV-negative tissues, and in these tissues, a substantial percentage of TUNEL-positive (TUNEL+) cells contained the FeMV P protein (mean, 37.4; range, 17.4-82.9), suggesting that induction of apoptosis may be an important mechanism for pathological changes associated with FeMV infection in cat kidney tissues.

Abstract
The genetic diversity of enterovirus G (EV-G) was investigated in the wild-boar population in Japan. EV-G-specific reverse transcription PCR demonstrated 30 (37.5 %) positives out of 80 faecal samples. Of these, viral protein 1 (VP1) fragments of 20 samples were classified into G1 (3 samples), G4 (1 sample), G6 (2 samples), G8 (4 samples), G11 (1 sample), G12 (7 samples), G14 (1 sample) and G17 (1 sample), among which 11 samples had a papain-like cysteine protease (PL-CP) sequence, believed to be the first discoveries in G1 (2 samples) or G17 (1 sample) wild-boar EV-Gs, and in G8 (2 samples) or G12 (6 samples) EV-Gs from any animals. Sequences of the non-structural protein regions were similar among EV-Gs possessing the PL-CP sequence (PL-CP EV-Gs) regardless of genotype or origin, suggesting the existence of a common ancestor for these strains. Interestingly, for the two G8 and two G12 samples, the genome sequences contained two versions, with or without the PL-CP sequence, together with the homologous 2C/PL-CP and PL-CP/3A junction sequences, which may explain how the recombination and deletion of the PL-CP sequences occured in the PL-CP EV-G genomes. These findings shed light on the genetic plasticity and evolution of EV-G.

Abstract
We sequenced the complete genome of a porcine torovirus (PToV) strain from Japan for the first time. Whole-genome analysis revealed that this strain (Iba/2018) has a mosaic sequence composed of at least three genome backgrounds, related to US, Chinese and German PToV strains. Clear recombination breakpoints were detected in the M and HE coding regions. A similarity plot and structural analysis demonstrated that the HE coding region exhibits the highest diversity, and the most sequence variation was found in the lectin domain. PToVs were divided into two lineages in the HE region, whereas clear lineages were not found in other regions.

Abstract
Sapoviruses (SaVs) are enteric viruses that have been detected in human and animals previously; however, SaVs have not been identified in wild boar yet. Using a metagenomics approach, we identified SaVs in fecal samples of free-living wild boars in Japan for the first time. Six of the 48 specimens identified belonged to one genogroup (G)III, one GV and four GVI SaV sequence reads. We successfully determined complete genome of GV and GVI SaV strains using the long reverse transcription PCR strategy and the 5' rapid amplification of cDNA end method. Phylogenetic tree analysis and pairwise distance calculation revealed that GV SaV detected from wild boar was related to recently assigned GV.5 strains from pig, while GVI SaV was assigned to a new genotype within GVI. Moreover, wild boar may act as a reservoir for transmission of SaVs to the pig population (and vice versa) because GIII, GV, and GVI SaVs were all detected in pigs previously.

Abstract
Sapoviruses (SaVs) are enteric viruses belonging to the family Caliciviridae that infect humans and animals, including pigs. To date, SaVs have been classified into 19 genogroups (G) based on complete VP1 sequences; however, complete genome sequences of some SaV Gs are not yet available. In this study, we determined the full genome sequences of four SaVs (two GX and two GXI SaVs) and analyzed them together with those of other SaVs. The complete genome sequences of GX and GXI SaVs, excluding the poly(A) tails, were 7124, 7142, 7170, and 7179 nucleotides, which were shorter than those of other SaVs, except for porcine GVI and GVII viruses. Genetic characterization revealed that GX SaVs and GXI SaVs shared common features with GVI and GVII viruses, such as the first 10 amino acid residues in the ORF1 coding region, a shorter ORF1 than that of the other genogroups, and the predicted secondary structure of the 5' end of the genome and the starting region of non-structural protein/structural protein junction. Phylogenetic analyses showed that GX and GXI SaVs branched with porcine GVI, GVII, and GIX SaVs and formed a clade consisting of only porcine SaVs. These findings suggest that porcine GX and GXI SaVs together with porcine GVI, GVII, and possibly GIX SaVs, evolved from a common ancestor in the porcine population.

Abstract
A 15-year-old neutered male Persian cat was presented with recurrent hematemesis and
melena. Abdominal ultrasonography and computed tomography revealed a mass in the proximal
descending duodenal wall. Endoscopic examination revealed hemorrhage on the luminal side
of the mass. Fine-needle aspiration of the mass was performed. Microscopic analysis
revealed a cluster of cells with oval nuclei and indistinct cell borders, suggesting a
neoplastic disease of neuroendocrine origin. The mass located near the major duodenal
papilla was partially resected, and the bleeding was stopped by cauterization. However,
the surgical procedures could not control the hemorrhage from the tumor mass, and the cat
died of severe anemia. Immunohistopathological analysis revealed that the tumor was a
duodenal carcinoid.

Abstract
A neutered male Golden Retriever was referred with a 2-week history of dry mouth. Multiple and bilateral enlargement of the lacrimal and salivary glands showing heterogeneous internal enhancement was identified on contrast-enhanced computed tomography (CT). Ultrasonographic examination detected multifocal hypoechoic areas within the swollen submandibular salivary glands, which were histopathologically diagnosed as lymphoplasmacytic sialoadenitis. As both imaging and histopathological findings were in accordance with those in human Sjögren's syndrome, a provisional diagnosis of Sjögren's-like syndrome was made. Immunosuppressive drugs promptly improved clinical signs concurrently with the abnormal sonographic findings, indicating the feasibility of ultrasonography in monitoring therapeutic outcomes. Herein, we discuss a proposed criteria set for diagnosis of Sjögren's-like syndrome in veterinary medicine.

Abstract
A 6-year-old neutered male Yorkshire Terrier presented with recurrent pericardial effusion. Although clinical examinations including computed tomography were inconclusive, an exploratory thoracotomy revealed multiple small nodules and plaques on the inner surface of the pericardial sac (Day 1). A subtotal pericardiectomy was performed to prevent cardiac tamponade due to the increasing pericardial effusion, and the resected section of the pericardium was histopathologically diagnosed with mesothelioma. After surgery, chemotherapy with intrathoracic carboplatin was commenced. During the course of the treatment, a detailed follow-up ultrasonographic scan was performed to detect early lesions disseminated on the pleura, originating from the primary pericardial mesothelioma. On Day 101, the minute pleural nodules, which were disseminated lesions as predicted, were successfully imaged by ultrasonography. As the clinical stage advanced, the nodules were observed to gradually increase in size and number, implying tumor progression. These observations highlight the feasibility of ultrasonography in detecting minute disseminated lesions at an early stage, monitoring tumor progression, and thereby, predicting the prognosis of canine pericardial mesothelioma.

Abstract
The Porcine Sapelovirus (PSV) is an enteric virus of pigs that can cause various disorders. However, there are few reports that describe the molecular characteristics of the PSV genome. In this study, almost the entire genomes of 23 PSVs detected in Japanese pigs were analyzed using bioinformatics. Analysis of the cis-active RNA elements showed that the predicted secondary structures of the internal ribosome entry site in the 5' untranslated region (UTR) and a cis-replication element in the 2C coding region were conserved among PSVs. In contrast, those at the 3' UTR were different for different PSVs; however, tertiary structures between domains were conserved across all PSVs. Phylogenetic analysis of nucleotide sequences of the complete VP1 region showed that PSVs exhibited sequence diversity; however, they could not be grouped into genotypes due to the low bootstrap support of clusters. The insertion and/or deletion patterns in the C-terminal VP1 region were not related to the topology of the VP1 tree. The 3CD phylogenetic tree was topologically different from the VP1 tree, and PSVs from the same country were clustered independently. Recombination analysis revealed that recombination events were found upstream of the P2 region and some recombination breakpoints involved insertions and/or deletions in the C-terminal VP1 region. These findings demonstrate that PSVs show genetic diversity and frequent recombination events, particularly in the region upstream of the P2 region; however, PSVs could currently not be classified into genotypes and conserved genetic structural features of the cis-active RNA elements are observed across all PSVs.

Abstract
Background A549 carrier cells infected with oncolytic adenovirus can induce complete tumor reduction of subcutaneous ovarian tumors but not intraperitoneal disseminated ovarian tumors. This appears to be a result of the insufficient antitumor effect of A549 carrier cells. Therefore, in the present study, we cloned a novel carrier cell with the aim of improving the antitumor effects. Methods Carrier cells infected with oncolytic adenovirus AdE3‐midkine with a midkine promoter were cloned by limiting dilution. We examined the antitumor effects of these cells on subcutaneous and intraperitoneal OVHM ovarian tumors in a syngeneic mouse model. Biosafety tests were conducted in beagle dogs and rabbits. Results We cloned EHMK‐51‐35 carrier cells with 10‐fold higher antitumor effects compared to A549 carrier cells in vitro. EHMK‐51‐35 carrier cells co‐infected with AdE3‐midkine and Ad‐mGM‐CSF induced a 100% complete tumor reduction in subcutaneous tumors and a 60% reduction of intraperitoneal disseminated tumors. Single‐dose acute toxicity test on beagle dogs with EHMK‐51‐35 carrier cells co‐infected with AdE3‐midkine and Ad‐cGM‐CSF showed no serious side effects. Biologically active adenoviruses were not detected in the blood, saliva, feces, urine or whole organs. In a chronic toxicity test, VX2 tumors in rabbits were injected five times with EHMK‐51‐35 carrier cells infected with AdE3‐midkine and these rabbits showed no serious side effects. Conclusions Significant antitumor effects and safety of cloned EHMK‐51‐35 carrier cells were confirmed in intraperitoneal ovarian tumors and toxicity tests, respectively. These findings will be extended to preclinical efficacy studies using dogs and cats, with the aim of conducting human clinical trials on refractory solid tumors.

Abstract
Feline morbillivirus (FeMV) is an emerging member of morbillivirus discovered in 2012. Although association of FeMV infection with kidney diseases in cats has been suggested, the pathogenicity of the virus has not been clear to date. To study the association between FeMV infection and pathological changes in kidney tissues of infected cats, we performed immunohistochemistry and immunofluorescent assays to detect FeMV antigens and analyzed the effect of FeMV infection on the pathological changes in the kidney tissues. In 38 kidney tissue samples from cats, some tissue injury scores were significantly higher when the FeMV antigens were detected, especially those for the tubular tissues in which the FeMV antigens were mostly localized. Pathological changes associated with the FeMV antigens included the ones typically found in chronic kidney diseases, such as interstitial cell infiltration, glomerulosclerosis, tubular atrophy and fibrosis. We also detected some feline IgG localizations in glomerular tissues, though co-localization or significant association with the FeMV antigens were not found. Our study confirms the association of FeMV infection with some kidney tissue injuries and provides additional information about roles of FeMV infection in chronic kidney diseases.

Abstract
EMCV genome was widely found in fecal guanos in Taiwanese, Korean, and Japanese caves. Miniopterus fuliginosus is the main source of the fecal guano. It is possible that Miniopterus fuliginosus is one of the natural hosts of EMCV in East Asia.
Bats are reservoir hosts of many zoonotic viruses and identification of viruses that they carry is important. This study aimed to use high throughput screening to identify the viruses in fecal guano of Taiwanese insectivorous bats caves in order to obtain more information on bat-derived pathogenic viruses in East Asia. Guano samples were collected from two caves in Taiwan, pooled, and then subjected to Multiplex PCR-based next generation sequencing for viral identification. Subsequently, encephalomyocarditis virus (EMCV) sequence was detected and confirmed by reverse transcription PCR. EMCV is considered as rodent virus and thus, animal species identification through cytochrome oxidase I (COI) barcoding was further done to identify the viral source. Finally, determination of distribution and verification of the presence of EMCV in guano obtained from Japanese and South Korean caves was also done. We concluded that the guano collected was not contaminated with the excrement of rodents which were reported and presumed to live in Taiwan. Also, EMCV genome fragments were found in guanos of Japanese and South Korean caves. It is possible that the eastern bent-wing bat (Miniopterus fuliginosus) is one of the natural hosts of EMCV in East Asia.

Abstract
Porcine Teschoviruses (PTVs) are associated with polioencephalomyelitis and various diseases, including reproductive and gastrointestinal disorders, of pigs and wild boars, and are also detected in the feces of healthy pigs. The genus Teschovirus contains a single species Teschovirus A that currently includes 13 serotypes. In the present study, we identified novel PTVs that are distantly related to Teschovirus A and were found in fecal samples of pigs with or without diarrhea in Japan. Phylogenetic analysis of amino acid (aa) sequences of the complete coding region revealed that these newly identified viruses did not cluster with any strains of PTVs or other strains within the picornavirus supergroup 1, suggesting that the viruses may not belong to Teschovirus A or any genus of the family Picornaviridae. These novel PTVs share a type IV internal ribosomal entry site and conserved characteristic motifs in the coding region, yet exhibit 62.2-79.0%, 86.6-92.8%, 77.1-81.0%, and 84.3-86.7% aa identities to PTV strains in P1, 2C, 3C, and 3D regions, respectively. In contrast, PTV 1-13 strains of the Teschovirus A share 76.5-92.1%, 88.1-99.7%, 93.2-100%, and 95.8-100% aa identities in the P1, 2C, 3C, and 3D, respectively, within the species. These data imply that the newly identified viruses belong to teschoviruses, and may represent a novel species in the genus Teschovirus.

Abstract
A novel virus related to the Enterovirus/Sapelovirus supergroup in the family Picornaviridae was identified in healthy porcine feces in Japan by using a metagenomics approach. The genome of the virus, named Sapelo-like porcine picornavirus Japan (SPPVJ) Pig/Isi-Im1/JPN/2016, had a type-IV internal ribosomal entry site and carried a 6978-nucleotide-long single open reading frame encoding a 2326 amino acids (aa) polyprotein precursor. The coding sequence region consisted of leader protein (68 aa), a structural protein region P1 (824 aa), and the non-structural protein regions P2 (672 aa) and P3 (762 aa). Among representative picornaviruses, the P1, 2C, and 3CD regions of SPPVJ had the highest aa identities of 64.4%, 61.9%, and 73.3%, respectively, with the corresponding regions of sapelo-like bat picornavirus BtVs-PicoV/SC2013. Sequencing analysis of the RT-PCR products derived from the 5' untranslated and 3D regions revealed the presence of SPPVJ in 17.8% (19/107) of the feces from healthy and diarrheal pigs in 12 farms in 2015-2016. Further studies are needed to determine the origin and pathogenic potential of SPPJV in pigs and other mammals.

Abstract
Swine influenza viruses (SIVs) are important not only for pig farming, but also for public health. In fact, pandemic A(H1N1) 2009 viruses [A(H1N1)pdm09] were derived from SIVs. Therefore, timely characterization of locally circulating SIVs is necessary for understanding the global status of SIVs. To genetically characterize SIVs circulating in Japanese pig populations, we isolated 24 SIVs of three subtypes (17 H1N1, four H1N2 and three H3N2 strains) from 14 pig farms in Japan from 2013 to 2016. Genetic analyses revealed that the haemagglutinin (HA) and neuraminidase (NA) genes of the 17 H1N1 and the HA gene of one H1N2, A/swine/Aichi/02/2016 (H1N2), SIVs belonged to the A(H1N1)pdm09 lineage. More importantly, all of the remaining six gene segments (i.e., PB1, PB1, PA, NP, M and NS) of the 24 SIVs, regardless of the HA and NA subtype, were also classified as belonging to the A(H1N1)pdm09 lineage. These results indicate that gene segments of A(H1N1)pdm09 lineage are widely distributed in SIVs circulating in Japanese pig populations In addition, the NA gene of A/swine/Aichi/02/2016 (H1N2) shared less than 88.5% nucleotide identity with that of the closest relative A/swine/Miyagi/5/2003 (H1N2), which was isolated in Japan in 2003. These results indicate the sustained circulation of classical H1N2-derived SIVs with remarkable diversity in the NA genes in Japanese pig populations. These findings highlight the necessity of both intensive biosecurity systems and active SIV surveillance in pig populations worldwide for both animal and public health.

Abstract
Recently, there have been reports of new members of posavirus-like viruses in the order Picornavirales. In this study, using a metagenomics approach, 11 posavirus-like sequences (>7,000 nucleotides) were detected in 155 porcine fecal samples. Phylogenetic analysis revealed that the newly identified virus sequences, together with other posavirus-like viruses, form distinct clusters within the order Picornavirales, composed of eight genogroups and unassigned sequences based on amino acid sequences of the helicase and RNA-dependent RNA polymerase regions, with <40 % and <50 % sequence identity, respectively. We propose further classifications of highly diverse posavirus populations based on newly identified sequences from Japanese pig feces.

Abstract
Porcine rotavirus C (RVC) is distributed throughout the world and is thought to be a pathogenic agent of diarrhea in piglets. Although, the VP7, VP4, and VP6 gene sequences of Japanese porcine RVCs are currently available, there is no whole-genome sequence data of Japanese RVC. Furthermore, only one to three sequences are available for porcine RVC VP1-VP3 and NSP1-NSP3 genes. Therefore, we determined nearly full-length whole-genome sequences of nine Japanese porcine RVCs from seven piglets with diarrhea and two healthy pigs and compared them with published RVC sequences from a database. The VP7 genes of two Japanese RVCs from healthy pigs were highly divergent from other known RVC strains and were provisionally classified as G12 and G13 based on the 86% nucleotide identity cut-off value. Pairwise sequence identity calculations and phylogenetic analyses revealed that candidate novel genotypes of porcine Japanese RVC were identified in the NSP1, NSP2 and NSP3 encoding genes, respectively. Furthermore, VP3 of Japanese porcine RVCs was shown to be closely related to human RVCs, suggesting a gene reassortment event between porcine and human RVCs and past interspecies transmission. The present study demonstrated that porcine RVCs show greater genetic diversity among strains than human and bovine RVCs.

Abstract
Akabane virus (AKAV) belongs to the Simbu serogroup of the genus Orthobunyavirus in the family Bunyaviridae. It has been shown that AKAV induces apoptosis in mammalian cells. It is necessary to understand the signaling pathways involved in AKAV-induced apoptosis to further elucidate the molecular virology of AKAV. c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK) are mediators of apoptosis; therefore, we investigated the roles of JNK and p38 MAPK cascades in AKAV-infected cells. We found that JNK and p38 MAPK as well as their downstream substrates, c-Jun and heat shock protein 27 (HSP27), were phosphorylated in response to AKAV infection. A JNK inhibitor (SP600125) inhibited AKAV-mediated apoptosis whereas a p38 MAPK inhibitor (SB203580) did not. We conclude that AKAV infection activates the JNK and p38 MAPK signaling pathways, and the JNK cascade plays a crucial role in AKAV-induced apoptosis in vitro. JNK and p38 MAPK were phosphorylated in response to Akabane virus infection. Downstream substrates, c-Jun and heat shock protein 27, were also phosphorylated by viral infection. JNK inhibitor (SP600125) inhibited AKAV-mediated apoptosis whereas a p38 MAPK inhibitor (SB203580) did not.

Abstract
Tumor necrosis factor (TNF)/TNF receptors (TNFR1/TNFR2) are considered to be potential drug targets to treat refractory diseases, including autoimmune diseases and malignant tumors. However, their specific functions, especially in the case of TNFR2, are poorly understood. In this study, we constructed a mouse TNFR2 (mTNFR2)-mediated biological assay system that shows no effects of mouse TNFR1 (mTNFR1) in order to screen mTNFR2-selective stimulating agents. Mouse TNFR1(-/-)R2(-/-) preadipocytes were transfected with the gene encoding the mTNFR2/mouse Fas (mFas) chimeric receptor in which the extracellular and transmembrane domains of mTNFR2 were fused to the intracellular domain of mFas. Our results demonstrated that this cell line exhibits highly sensitive mTNFR2-mediated cytotoxic effects. We propose that this mTNFR2-mediated biological assay system would be a useful tool to screen for mTNFR2-selective stimulating agents.

Abstract
Porcine diarrhea caused by viruses is a major problem of the pig farming industry and can result in substantial losses of revenue. Thus, diagnosing the infectious agents is important to prevent and control diseases in pigs. We developed novel one-step real-time quantitative RT-PCR (qPCR) assays that can detect four porcine diarrheal viruses simultaneously: porcine epidemic diarrhea virus (PEDV), transmissible gastroenteritis virus (TGEV), porcine deltacoronavirus (PDCoV), and porcine group A rotavirus (PRVA). The qPCR analysis takes only 75 minutes to detect the presence of the four viruses. The limits of detection of our new assays for PEDV, TGEV, PDCoV, and PRVA were 100, 10, 10 and 10 copies per reaction, respectively. The sensitivity of qPCR was 1-1000 times higher than that of published gel-based RT-PCR. We used our qPCR method to successfully diagnose clinical samples from infected pigs, and no false positive results were obtained. In conclusion, qPCR can drastically reduce the diagnostic time to detect viruses compared to currently employed methods. We predict that the qPCR assays will become a useful tool for detecting viral infections that cause diarrhea and other complications in pigs.

Abstract
Bovine toroviruses (BToVs), belong to the subfamily Toroviridae within the family Coronaviridae, and are pathogens, causing enteric disease in cattle. In Japan, BToVs are distributed throughout the country and cause gastrointestinal infection of calves and cows. In the present study, complete genome sequences of two Japanese BToVs and partial genome sequences of two Japanese BToVs and one porcine torovirus (PToV) from distant regions in Japan were determined and genetic analyses were performed. Pairwise nucleotide comparison and phylogenetic analyses revealed that Japanese BToVs shared high identity with each other and showed high similarities with BToV Breda1 strain in S, M, and HE coding regions. Japanese BToVs showed high similarities with porcine toroviruses in ORF1a, ORF1b, and N coding regions and the 5′ and 3′ untranslated regions, suggestive of a natural recombination event. Recombination analyses mapped the putative recombinant breakpoints to the 3′ ends of the ORF1b and HE regions. These findings suggest that the interspecies recombinant nature of Japanese BToVs resulted in a closer relationship between BToV Breda1 and PToVs. Recombination events between porcine and bovine torovirus were identified. Recombinant breakpoints were mapped at ORF1b and HE coding regions. These recombinant viruses are prevalent throughout Japan.

Abstract
Diarrhea in cattle is one of the most economically costly disorders, decreasing milk production and weight gain. In the present study, we established a novel simultaneous detection system using TaqMan real-time PCR designed as a system for detection of microbes from bovine diarrhea using real-time PCR (referred to as Dembo-PCR). Dembo-PCR simultaneously detects a total of 19 diarrhea-causing pathogens, including viruses, bacteria and protozoa. Specific primer-probe sets were newly designed for 7 pathogens and were synthesized on the basis of previous reports for 12 pathogens. Assays were optimized to react under the same reaction conditions. The PCR efficiency and correlation coefficient (R(2)) of standard curves for each assay were more than 80% and 0.9766, respectively. Furthermore, the sensitivity of Dembo-PCR in fecal sample analysis was measured with feces spiked with target pathogens or synthesized DNA that included specific nucleotide target regions. The resulting limits of detection (LOD) for virus-spiked samples, bacteria and DNA fragments were 0.16-1.6 TCID50 (PFU/reaction), 1.3-13 CFU/reaction and 10-100 copies/reaction, respectively. All reactions showed high sensitivity in pathogen detection. A total of 8 fecal samples, collected from 6 diarrheic cattle, 1 diarrheic calf and 1 healthy cow, were tested using Dembo-PCR to validate the assay's clinical performance. The results revealed that bovine coronavirus had infected all diarrheic adult cattle and that bovine torovirus had infected the diarrheic calf. These results suggest that Dembo-PCR may be a powerful tool for diagnosing infectious agents in cattle diarrhea.

Abstract
During surveillance for bovine diarrhea of unknown causes in Japanese black cattle in Kagoshima Prefecture,
Japan, we found two types of novel kobu-like viruses in fecal samples of calves. Sequence analyses revealed
that they had L protein and 2A protein with H-box/NC sequence motif, which are present in kobuviruses.
Phylogenetic analysis revealed that they were related to kobuviruses; however, they clustered apart from other
kobuviruses. In the prevalence study of two types of novel kobu-like viruses, 16.9% and 10.4% prevalence of
these viruses were observed in the feces of diarrheal calves in this area.

Abstract
We identified novel viruses in feces from cattle with diarrhea collected in 2009 in Hokkaido Prefecture, Japan, by using a metagenomics approach and determined the (near) complete sequences of the virus. Sequence analyses revealed that they had a standard picornavirus genome organization, i.e. 5' untranslated region (UTR) - L- P1 (VP4- VP3- VP2- VP1) - P2 (2A- 2B- 2C) - P3 (3A- 3B- 3C-3D) - 3'UTR- poly(A). They are closely related to other unclassified Chinese picornaviruses; bat picornaviruses group 1-3, feline picornavirus, and canine picornavirus, sharing 45.4-51.4% (P1), 38.0-44.9% (P2), and 49.6-53.3% (P3) amino acid identities, respectively. The phylogenetic analyses and detailed genome characterization showed that they, together with the unclassified Chinese picornaviruses, grouped as a cluster for the P1, 2C, 3CD and VP1 coding regions. These viruses had conserved features (e.g. predicted protein cleavage sites, presence of a leader protein, 2A, 2C, 3C, and 3D functional domains), suggesting they have a common ancestor. Reverse-transcription-PCR assays, using specific primers designed from the 5'UTR sequence of these viruses, showed that 23.0% (20/87) of fecal samples from cattle with diarrhea were positive, indicating the prevalence of these picornavirus in the Japanese cattle population in Hokkaido Prefecture. However, further studies are needed to investigate the pathogenic potential and etiological role of these viruses in cattle.
