Abstract
Severe fever with thrombocytopenia syndrome (SFTS) is an infectious disease caused by a tick-borne virus called severe fever with thrombocytopenia syndrome virus (SFTSV). In recent years, human infections through contact with ticks and through contact with the bodily fluids of infected dogs and cats have been reported; however, no vaccine is currently available. SFTSV has two glycoproteins (Gn and Gc) on its envelope, which are vaccine-target antigens involved in immunogenicity. In the present study, we constructed novel SFTS vaccine candidates using an adeno-associated virus (AAV) vector to transport the SFTSV glycoprotein genome. AAV vectors are widely used in gene therapy and their safety has been confirmed in clinical trials. Recently, AAV vectors have been used to develop influenza and SARS-CoV-2 vaccines. Two types of vaccines (AAV9-SFTSV Gn and AAV9-SFTSV Gc) carrying SFTSV Gn and Gc genes were produced. The expression of Gn and Gc proteins in HEK293T cells was confirmed by infection with vaccines. These vaccines were inoculated into mice, and the collected sera produced anti-SFTS antibodies. Furthermore, sera from AAV9-SFTSV Gn infected mice showed a potent neutralizing ability, similar to previously reported SFTS vaccine candidates that protected animals from SFTSV infection. These findings suggest that this vaccine is a promising candidate for a new SFTS vaccine.

Abstract
PURPOSE/OBJECTIVE(S) Our institute conducted a clinical trial of curative partial breast irradiation using carbon ion radiotherapy (CIRT) to patients with stage 0 and I breast cancer since 2013. The purpose of this report is to evaluate treatment outcomes up to now. MATERIALS/METHODS To date, we have conducted three clinical trials and one advanced medical treatment (NIRS 9404 Comprehensive Research). The first study (UMIN000010848: commonly known as Breast I trial) was 4-split irradiation for stage I low-risk patients aged 60 years or older, and the next clinical study (UMIN000029478: commonly known as Breast II trial) was for Tis-1N0M0 cases of 2 cm or less. On the other hand, 4-split irradiation using standard adjuvant drug therapy according to risk combined with whole breast irradiation by X-ray, the latest clinical trial (UMIN000046859: commonly known as Breast III trial) is a single irradiation for Tis-1N0M0 patients aged 50 years or older. be. In each phase I, the dose increase test was performed, and in phase II, treatment was performed with the recommended dose determined in phase I. Advanced medical care was provided in parallel with breast I for stage I breast cancer that was difficult or rejected to participate in breast I trial. RESULTS By January 2023, 60 cases were enrolled. A total of 19 were enrolled In Breast I, 7 in Phase I, 12 in Phase II of the recommended dose of 60.0 Gy (RBE). A total of 14 were enrolled in the 9404 Comprehensive Research. A total of 17 were enrolled In Breast II, 5 cases in Phase I, 12 cases in Phase II of recommended dose 60.0 Gy (RBE). A total of 10 were enrolled in Breast III, 6 cases in Phase I, and 4 in Phase II of recommended dose 50.0 Gy (RBE). As acute adverse events, grade 2 of acute radiation dermatitis were observed in 1 case, grade 1 of acute radiation dermatitis was observed in 31 cases, and grade 1 of mastitis was observed in 6 cases. As a late adverse event, grade 3 of pneumonia of unknown causality were observed in one case, but there were no other problematic adverse events, and breast cosmetic outcome was excellent in all cases. Tumor disappearance after CIRT took 3 to 24 months. Local recurrence and axillary lymph node metastasis were observed in one high-risk case of advanced medical treatment who refused any other therapy. Two cases had ipsilateral intramammary metachronous breast cancer with different subtypes. To date, no other recurrences or metastases have been observed. CONCLUSION CIRT for early-stage breast cancer is expected to be effective with mild adverse events, and it is considered meaningful to continue research.

Abstract
Environmental pollution caused by antimicrobial resistance is a global public health concern. To investigate the contribution of nutrias (Myocastor coypus) to the presence of extended-spectrum β-lactamase (ESBL)-producing Enterobacterales in the Ijira River, prevalence of ESBL-producing Enterobacterales in their feces was examined using deoxycholate-hydrogen sulfide-lactose agar containing cefotaxime. Additionally, the composition of the fecal microbiota of nutria was examined using DNA metabarcoding analysis of the 16S ribosomal RNA gene and compared with that of Amami rabbit, deer, fox, and raccoon dog. The absence of ESBL-producing Enterobacterales and substantially lower abundance of Enterobacterales was observed in the feces of nutrias than in those of other wild mammals. Our results suggest the low potential of antimicrobial-resistant Enterobacterales persistence and dissemination by nutria.

Abstract
Male killing (MK) is a type of reproductive manipulation induced by microbes, where sons of infected mothers are killed during development. MK is a strategy that enhances the fitness of the microbes, and the underlying mechanisms and the process of their evolution have attracted substantial attention. Homona magnanima, a moth, harbors two embryonic MK bacteria, namely, Wolbachia (Alphaproteobacteria) and Spiroplasma (Mollicutes), and a larval MK virus, Osugoroshi virus (OGV; Partitiviridae). However, whether the three distantly related male killers employ similar or different mechanisms to accomplish MK remains unknown. Here, we clarified the differential effects of the three male killers on the sex-determination cascades and development of H. magnanima males. Reverse transcription-PCR demonstrated that Wolbachia and Spiroplasma, but not OGVs, disrupted the sex-determination cascade of males by inducing female-type splice variants of doublesex (dsx), a downstream regulator of the sex-determining gene cascade. We also found that MK microbes altered host transcriptomes in different manners; Wolbachia impaired the host dosage compensation system, whereas Spiroplasma and OGVs did not. Moreover, Wolbachia and Spiroplasma, but not OGVs, triggered abnormal apoptosis in male embryos. These findings suggest that distantly related microbes employ distinct machineries to kill males of the identical host species, which would be the outcome of the convergent evolution. IMPORTANCE Many microbes induce male killing (MK) in various insect species. However, it is not well understood whether microbes adopt similar or different MK mechanisms. This gap in our knowledge is partly because different insect models have been examined for each MK microbe. Here, we compared three taxonomically distinct male killers (i.e., Wolbachia, Spiroplasma, and a partiti-like virus) that infect the same host. We provided evidence that microbes can cause MK through distinct mechanisms that differ in the expression of genes involved in sex determination, dosage compensation, and apoptosis. These results imply independent evolutionary scenarios for the acquisition of their MK ability.

Abstract
Antimicrobial resistance is a global concern requiring a one‐health approach. Given wild animals can harbor antimicrobial‐resistant bacteria (ARB), we investigated their presence in 11 fecal samples from wild animals using deoxycholate hydrogen sulfide lactose agar with or without cefotaxime (CTX, 1 mg/L). Thus, we isolated CTX‐resistant Escherichia coli from two Japanese red fox fecal samples. One strain was O83:H42‐ST1485‐fimH58 CTX‐M‐55‐producing E. coli carrying the genes aph(3″)‐Ib, aph(3′)‐Ia, aph(6)‐Id, mdf(A), sitABCD, sul2, tet(A), and tet(B), whereas the other was O25:H4‐ST131‐fimH30 CTX‐M‐14‐producing E. coli carrying mdf(A) and sitABCD and showing fluoroquinolone resistance. Thus, the presence of extended‐spectrum β‐lactamase producers in wild foxes suggests a spillover of ARB from human activities to these wild animals.

Abstract
Dog bladder cancer (BC) is mostly muscle-invasive (MI) with poor prognosis, and its pathogenesis is close to human MIBC. Three-dimensional (3D) organoid culture ensures novel knowledge on cancer diseases including BC. Recently, we have established dog BC organoids (BCO) using their urine samples. BCO recapitulated the epithelial structures, characteristics, and drug sensitivity of BC-diseased dogs. However, organoids from dog normal bladder epithelium are not established yet. Therefore, the present study aimed to establish dog normal bladder organoids (NBO) for further understanding the pathogenesis of dog BC and human MIBC. The established NBO underwent various analyzes including cell marker expressions, histopathological structures, cancer-related gene expression patterns, and drug sensitivity. NBO could be produced non-invasively with a continuous culturing and recapitulated the structures and characteristics of the dog's normal bladder mucosal tissues. Different drug sensitivities were observed in each NBO. The analysis of RNA sequencing revealed that several novel genes were changed in NBO compared with BCO. NBO showed a higher expression of p53 and E-cadherin, but a lower expression of MDM2 and Twist1 compared with BCO. These results suggest that NBO could be a promising experimental 3D model for studying the developmental mechanisms of dog BC and human MIBC.

Abstract
Macrorhabdus ornithogaster (MO) is an infectious fungus that causes
gastric damage in birds. In this study, we established nested and seminested polymerase
chain reaction (PCR) methods that specifically amplify the domain D1/D2 region (D1/D2) of
26S ribosomal DNA (rDNA), internal transcribed spacer (ITS) of rDNA, and intergenic spacer
(IGS) 1 region from avian feces. Phylogenetic analysis of MO collected from Japanese pet
birds showed little genetic variation; analysis based on these regions did not distinguish
between host species order, differences in MO shape, or host gastrointestinal symptoms.
These regions were found to be unsuitable for molecular epidemiological studies of MO and
further investigation into other genetic regions is required.

Abstract
Here, we performed next-generation sequencing (NGS) on six large flying foxes (Pteropus vampyrus) collected in Indonesia. Seventy-five virus species in the liver tissue of each specimen were listed. Viral homologous sequences in the bat genome were identified from the listed viruses. This finding provides collateral evidence of viral endogenization into the host genome. We found that two of the six specimens bore partial sequences that were homologous to the plant pathogens Geminiviridae and Luteoviridae. These sequences were absent in the P. vampyrus chromosomal sequences. Hence, plant viral homologous sequences were localized to the hepatocytes as extrachromosomal DNA fragments. Therefore, this suggests that the bat is a potential carrier or vector of plant viruses. The present investigation on wild animals offered novel perspectives on viral invasion, variation, and host interaction.

Abstract
Antimicrobial-resistant (AMR) bacteria affect human and animal health worldwide. Here, CTX-M-14-producing Escherichia coli isolates were isolated from Siberian weasels (Mustela sibirica) that were captured on a veterinary campus. To clarify the source of bacteria in the weasels, we examined the domestic animals reared in seven facilities on the campus. Extended-spectrum β-lactamase (ESBL)-producing E. coli were isolated on deoxycholate hydrogen sulfide lactose agar, containing cephalexin (50 μg/mL) or cefotaxime (2 μg/mL), and were characterized with antimicrobial susceptibility testing, pulsed-field gel electrophoresis (PFGE), replicon typing, and β-lactamase typing analyses. Next-generation sequencing of the ESBL-encoding plasmids was also performed. CTX-M-14 producers isolated from both domestic animals and weasels were classified into six clusters with seven PFGE profiles. The PFGE and antimicrobial resistance profiles were characterized by the animal facility. All CTX-M-14 plasmids belonged to the IncI1 type with a similar size (98.9–99.3 kb), except for one plasmid that was 105.5 kb in length. The unweighted pair group method with arithmetic mean (UPGMA) revealed that the CTX-M-14 plasmid in the weasel isolates might have the same origin as the CTX-M-14 plasmid in the domestic animals. Our findings shed further light on the association of antimicrobial resistance between wild and domestic animals.

Abstract
Two novel endornaviruses, Phytophthora endornavirus 2 (PEV2) and Phytophthora endornavirus 3 (PEV3) were found in isolates of a Phytophthora pathogen of asparagus collected in Japan. A molecular phylogenetic analysis indicated that PEV2 and PEV3 belong to the genus Alphaendornavirus. The PEV2 and PEV3 genomes consist of 14,345 and 13,810 bp, and they contain single open reading frames of 4,640 and 4,603 codons, respectively. Their polyproteins contain the conserved domains of an RNA helicase, a UDP-glycosyltransferase, and an RNA-dependent RNA polymerase, which are conserved in other alphaendornaviruses. PEV2 is closely related to Brown algae endornavirus 2, whereas PEV3 is closely related to Phytophthora endornavirus 1 (PEV1), which infects a Phytophthora sp. specific to Douglas fir. PEV2 and PEV3 were detected at high titers in two original Phytophthora sp. isolates, and we found a sub-isolate with low titers of the viruses during subculture. We used the high- and low-titer isolates to evaluate the effects of the viruses on the growth, development, and fungicide sensitivities of the Phytophthora sp. host. The high-titer isolates produced smaller mycelial colonies and much higher numbers of zoosporangia than the low-titer isolate. These results suggest that PEV2 and PEV3 inhibited hyphal growth and stimulated zoosporangium formation. The high-titer isolates were more sensitive than the low-titer isolate to the fungicides benthiavalicarb-isopropyl, famoxadone, and chlorothalonil. In contrast, the high-titer isolates displayed lower sensitivity to the fungicide metalaxyl (an inhibitor of RNA polymerase I) when compared with the low-titer isolate. These results indicate that persistent infection with PEV2 and PEV3 may potentially affect the fungicide sensitivities of the host oomycete.

Abstract
Recently, hepe-astrovirus-like RNA viruses named bastroviruses (BastVs), have been found in human, pig, bat, and rat fecal samples. In this study, we determined nearly complete genome sequences of four BastVs in the feces of healthy pigs. Genetic characterization revealed that these porcine BastVs (PBastVs) and BastVs from other animals including humans, had the same genome organization, that is, they contained three predicted conserved domains of viral methyltransferase, RNA helicase, and RdRp in the nonstructural ORF1 and the astrovirus capsid domain in the structural ORF2. Phylogenetic analyses using RNA-dependent RNA polymerase and the capsid region revealed that PBastVs branched with bat and rat BastVs; however, the groups formed by each host were distantly related to human BastVs. Pairwise amino acid sequence comparison demonstrated that PBastVs shared 95.2-98.6% and 76.1-95.5% sequence identity among each other in the ORF1 and ORF2 regions, respectively; the sequence identities between PBastVs and BastVs from other animals were 21.4-42.5% and 9.1-20.6% in the ORF1 and ORF2 regions, respectively. This suggested that BastVs were derived from a common ancestor but evolved independently in each host population during a prolonged period. Putative recombination events were identified in the PBastV genome, suggesting that PBastVs gain sequence diversity and flexibility through recombination events. In an analysis of previously obtained metagenomic data, PBastV sequence reads were detected in 7.3% (23/315) of fecal samples from pigs indicating that PBastVs are distributed among pig populations in Japan.

Abstract
Abstract
Background
Diabetes mellitus (DM) is a strong risk factor for major cardiac and cerebrovascular events. In particular, coronary artery disease with DM is often complicated with complex lesions. Drug-eluting stents (DES) are mainly used for these lesions, and dual-antiplatelet therapy (DAPT) has been used to prevent stent thrombosis. Early arterial healing after DES implantation may enable short DAPT strategy. However, the impact of DM on the arterial healing in the early phase has not been elucidated to date.
Purpose
We evaluated the arterial healing in the early phase after DES implantation using coronary angioscopy (CAS) and compared the findings between DM and non-DM patients.
Methods
This study was a multicenter retrospective observational study. We analyzed CAS findings of 337 lesions from 270 patients which were evaluated 3 to 5 months after DES implantation. Patients were divided into two groups: DM (149 lesions in 118 patients) versus non-DM groups (188 lesions in 152 patients). We assessed neointimal coverage (NIC) grades (maximum, minimum and dominant), thrombus adhesion and maximum yellow color of plaque underneath the stent. NIC was graded as follows: grade 0, stent struts were not covered; grade 1, stent struts were covered by thin layer; grade 2, stent struts were buried under neointima. Yellow color was graded as follows: grade 0, white; grade 1, light yellow; grade 2, yellow; grade 3, intensive yellow.
Results
Minimum NIC coverage grade was lower in DM group than in non-DM group (P=0.002, Figure), while maximum and dominant NIC coverage grades were similar between them (P=0.94 and P=0.59, respectively). Thrombus adhesion (44.3% versus 38.8%, P=0.32) and maximum yellow color grade (P=0.78) were also similar between DM and non-DM groups. Even after the adjustment by the confounding factors such as follow-up duration and primary disease of acute coronary syndrome, DM was an independent factor predicting grade 0 of minimum NIC (odds ratio [OR] 1.83 [95% confidence interval 1.11–3.03], P=0.019).
Conclusion
DM patients showed less covered struts than non-DM patients 3 to 5 months after DES implantation, suggesting that the recent ultra-short DAPT strategy might not be easily applicable to DM patients.

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
Mosquitoes transmit many kinds of arboviruses (arthropod-borne viruses), and numerous arboviral diseases have become serious problems in Indonesia. In this study, we conducted surveillance of mosquito-borne viruses at several sites in Indonesia during 2016-2018 for risk assessment of arbovirus infection and analysis of virus biodiversity in mosquito populations. We collected 10,015 mosquitoes comprising at least 11 species from 4 genera. Major collected mosquito species were Culex quinquefasciatus, Aedes albopictus, Culex tritaeniorhynchus, Aedes aegypti, and Armigeres subalbatus. The collected mosquitoes were divided into 285 pools and used for virus isolation using two mammalian cell lines, Vero and BHK-21, and one mosquito cell line, C6/36. Seventy-two pools showed clear cytopathic effects only in C6/36 cells. Using RT-PCR and next-generation sequencing approaches, these isolates were identified as insect flaviviruses (family Flaviviridae, genus Flavivirus), Banna virus (family Reoviridae, genus Seadornavirus), new permutotetravirus (designed as Bogor virus) (family Permutotetraviridae, genus Alphapermutotetravirus), and alphamesoniviruses 2 and 3 (family Mesoniviridae, genus Alphamesonivirus). We believed that this large surveillance of mosquitoes and mosquito-borne viruses provides basic information for the prevention and control of emerging and re-emerging arboviral diseases.

Although intensive vaccination programs have been implemented, Newcastle disease (ND)
outbreaks, accompanied by severe economic losses, are still reported in Egypt. The genetic
characterization of ND virus (NDV) strains isolated from ND-vaccinated chicken flocks
provides essential information for improving ND control strategies. Therefore, here, 38
NDV strains were isolated and identified from outbreaks among vaccinated flocks of broiler
chickens located in the provinces of Qena, Luxor, and Aswan of Upper Egypt during
2011–2013. The investigated broiler chicken flocks (aged 28 to 40 days) had high mortality
rates of up to 80%. All NDV isolates were genetically analyzed using next-generation DNA
sequencing. From these isolates, 10 representative NDV strains were selected for further
genetic analyses. Phylogenetic analysis of full-length coding genes revealed that the
Egyptian NDV isolates belonged to a single sub-genotype, VII.1.1. These isolates were
phylogenetically distant from the vaccine strains, including La Sota or Clone 30 (genotype
II), which have been commonly used to vaccinate chicken flocks. Amino acid substitution
K78R was observed in the neutralizing epitopes of the F proteins; whereas several
mutations were found in the neutralizing epitopes of the hemagglutinin-neuraminidase
proteins, notably, E347K. Overall, our results suggested that the occurrence of
neutralizing epitope variants may be one of potential reasons for ND outbreaks. Further
studies are needed to determine the protective effect of current vaccines against
circulating virulent NDV strains.

Abstract
The grasscutter (also known as the greater cane rat; Thryonomys swinderianus) is a large rodent native to West Africa that is currently under domestication process for meat production. However, little is known about the physiology of this species. In the present study, aiming to provide information about gut microbiota of the grasscutter and better understand its physiology, we investigated the intestinal microbiota of grasscutters and compared it with that of other livestock (cattle, goat, rabbit, and sheep) using 16S rRNA metagenomics analysis. Similar to the other herbivorous animals, bacteria classified as Bacteroidales, Clostridiales, Ruminococcaceae, and Lachnospiraceae were abundant in the microbiome of grasscutters. However, Prevotella and Treponema bacteria, which have fiber fermentation ability, were especially abundant in grasscutters, where the relative abundance of these genera was higher than that in the other animals. The presence of these genera might confer grasscutters the ability to easily breakdown dietary fibers. Diets for grasscutters should be made from ingredients not consumed by humans to avoid competition for resources and the ability to digest fibers may allow the use of fiber-rich feed materials not used by humans. Our findings serve as reference and support future studies on changes in the gut microbiota of the grasscutter as domestication progresses in order to establish appropriate feeding methods and captivity conditions.

Abstract
Non-alcoholic steatohepatitis (NASH) is associated with liver fibrosis and cirrhosis, which eventually leads to hepatocellular carcinoma. Although several animal models were developed to understand the mechanisms of NASH pathogenesis and progression, it remains obscure. A 3D organoid culture system can recapitulate organ structures and maintain gene expression profiles of original tissues. We therefore tried to generate liver organoids from different degrees [defined as mild (NASH A), moderate (NASH B) and severe (NASH C)] of methionine- and choline-deficient diet-induced NASH model mice and analyzed the difference of their architecture, cell components, organoid-forming efficacy, and gene expression profiles. Organoids from each stage of NASH model mice were successfully generated. Interestingly, epithelial-mesenchymal transition was observed in NASH C organoids. Expression of Collagen I and an activated hepatic stellite cell marker, α-sma was upregulated in the liver organoids from NASH B and C mice. The analysis of RNA sequencing revealed that several novel genes were upregulated in all NASH liver organoids. These results suggest that our generated liver organoids from different stages of NASH diseased mice might become a useful tool for in vitro studies of the molecular mechanism of NASH development and also for identifying novel biomarkers for early diagnosis of NASH disease.

Abstract
The etiology of Porcine respiratory disease complex is complicated by infections with
multiple pathogens, and multiple infections increase the difficulty in identifying the
causal pathogen. In this present study, we developed a detection system of microbes from
porcine respiratory by using TaqMan real-time PCR (referred to as Dempo-PCR) to screen a
broad range of pathogens associated with porcine respiratory diseases in a single run. We
selected 17 porcine respiratory pathogens (Actinobacillus
pleuropneumoniae, Boldetella bronchiseptica,
Haemophilus parasuis, Pasteurella multocida,
Pasteurella multocida toxin, Streptococcus suis,
Mycoplasma hyopneumoniae, Mycoplasma hyorhinis,
Mycoplasma hyosynovie, porcine circovirus 2, pseudorabies virus,
porcine cytomegalovirus, swine influenza A virus, porcine reproductive and respiratory
virus US strain, EU strain, porcine respiratory coronavirus and porcine hemagglutinating
encephalomyelitis virus) as detection targets and designed novel specific primer-probe
sets for seven of them. In sensitivity test by using standard curves from synthesized DNA,
all primer-probe sets showed high sensitivity. However, porcine reproductive and
respiratory virus is known to have a high frequency of genetic mutations, and the primer
and probe sequences will need to be checked at a considerable frequency when performing
Dempo-PCR from field samples. A total of 30 lung samples from swine showing respiratory
symptoms on six farms were tested by the Dempo-PCR to validate the assay’s clinical
performance. As the results, 12 pathogens (5 virus and 7 bacteria) were detected and
porcine reproductive and respiratory virus US strain, Mycoplasma
hyorhinis, Haemophilus parasuis, and porcine cytomegalovirus
were detected at high frequency. These results suggest that Dempo-PCR assay can be applied
as a screening system with wide detection targets.

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
A novel adenovirus outbreak occurred in a colony of African pygmy hedgehogs (APHs). An African pygmy hedgehog adenovirus 1 (AhAdV-1) infection was confirmed in 13 APHs. AhAdV-1 was isolated from one APH. Five APHs died during the outbreak and AhAdV-1 can cause fatal pneumonia in a case. AhAdV-1 should be monitored as a potential cause of emerging infections in APHs.
An African pygmy hedgehog adenovirus 1 (AhAdV-1) outbreak in a colony of 24 African pygmy hedgehogs (APHs) with a case of fatal pneumonia occurred in Japan. Thirteen out of a colony of 15 APHs with respiratory symptoms were diagnosed with AhAdV-1 infection based on the detection of AhAdV-1 genome in throat/nasal swabs and further one APH was diagnosed on isolation of the virus. Five infected APHs died during the outbreak and AhAdV-1 caused severe pneumonia and death in one case. After the outbreak, persistent AhAdV-1 infection was suggested in one surviving APH. AhAdV-1 is a novel adenovirus and is suspected to be an emerging pathogen.

Abstract
Our previous study reported that persistently infected (PI) cattle of bovine viral diarrhea virus (BVDV) have co-infected with BVDV/END- and /END+ that promote and inhibit host's type-I interferon (IFN) production, respectively. However, the relationship between co-infection of immunologically distinct BVDVs and persistent infection as well as the biological significance of END- viruses remains unknown. Experiments using cultured cells revealed that END+ virus, which is unable to propagate in situations where the host's immune response is induced by IFN-α addition, is able to propagate under those conditions when co-infecting with END- virus. These results indicate that BVDV/END- can coexist with BVDV/END+ and that co-infection with END- viruses supports the propagation of END+ viruses. Our in vitro experiments strongly suggest that co-infection with END- virus is involved in the maintenance of persistent infection of BVDV.

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
In human and dogs, bladder cancer (BC) is the most common neoplasm affecting the urinary tract. Dog BC resembles human muscle‐invasive BC in histopathological characteristics and gene expression profiles, and could be an important research model for this disease. Cancer patient‐derived organoid culture can recapitulate organ structures and maintains the gene expression profiles of original tumor tissues. In a previous study, we generated dog prostate cancer organoids using urine samples, however dog BC organoids had never been produced. Therefore we aimed to generate dog BC organoids using urine samples and check their histopathological characteristics, drug sensitivity, and gene expression profiles. Organoids from individual BC dogs were successfully generated, expressed urothelial cell markers (CK7, CK20, and UPK3A) and exhibited tumorigenesis in vivo. In a cell viability assay, the response to combined treatment with a range of anticancer drugs (cisplatin, vinblastine, gemcitabine or piroxicam) was markedly different in each BC organoid. In RNA‐sequencing analysis, expression levels of basal cell markers (CK5 and DSG3) and several novel genes (MMP28,CTSE,CNN3,TFPI2,COL17A1, and AGPAT4) were upregulated in BC organoids compared with normal bladder tissues or two‐dimensional (2D) BC cell lines. These established dog BC organoids might be a useful tool, not only to determine suitable chemotherapy for BC diseased dogs but also to identify novel biomarkers in human muscle‐invasive BC. In the present study, for the 1st time, dog BC organoids were generated and several specifically upregulated organoid genes were identified. Our data suggest that dog BC organoids might become a new tool to provide fresh insights into both dog BC therapy and diagnostic biomarkers.

Abstract
Enterovirus G (EV-G) belongs to the family of Picornaviridae. Two types of recombinant porcine EV-Gs carrying papain-like cysteine protease (PLCP) gene of porcine torovirus, a virus in Coronaviridae, are reported. Type 1 recombinant EV-Gs are detected in pig feces in Japan, USA, and Belgium and carry the PLPC gene at the junction site of 2C/3A genes, while PLPC gene replaces the viral structural genes in type 2 recombinant EV-G detected in pig feces in a Chinese farm. We identified a novel type 2 recombinant EV-G carrying the PLCP gene with flanking sequences in place of the viral structural genes in pig feces in Japan. The ~0.3 kb-long upstream flanking sequence had no sequence homology with any proteins deposited in GenBank, while the downstream ~0.9 kb-long flanking sequence included a domain having high amino acid sequence homology with a baculoviral inhibitor of apoptosis repeat superfamily. The pig feces, where the novel type 2 recombinant EV-G was detected, also carried type 1 recombinant EV-G. The amount of type 1 and type 2 recombinant EV-G genomes was almost same in the pig feces. Although the phylogenetic analysis suggested that these two recombinant EV-Gs have independently evolved, type 1 recombinant EV-G might have served as a helper virus by providing viral structural proteins for dissemination of the type 2 recombinant EV-G. A novel type 2 recombinant EV-G was discovered in pig feces in Japan. Type 2 recombinant EV-G carried the PLCP torovirus gene with unknown flanking genes, in place of the viral structural proteins. Amount of type 2 recombinant EV-G in the pig feces was almost same with type 1. Type 2 recombinant EV-G belonged to be a different cluster from the cluster of type 1.

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
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
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
Background Malaria incidence has been steadily declining in Cambodia, where the government is aiming to eliminate malaria by 2025. Successful malaria elimination requires active engagement and participation of communities to recognize malaria symptoms and the development of prompt treatment-seeking behavior for early diagnosis and appropriate treatment. This study examined malaria knowledge, preventive actions, and treatment-seeking behavior among different groups of ethnic minorities and Khmer in Ratanakiri Province, Cambodia. Methods Face-to-face interviews were conducted in December 2015, targeting 388 mothers with children under 2 years old, who belonged to ten ethnic minority groups or the Khmer group living in 62 rural villages in Ratanakiri. In addition to describing mothers’ knowledge and actions for malaria prevention, logistic regression analysis was performed to identify determinants of fever during the most recent pregnancy and among children under two. Results Overall 388 mothers were identified for enrollment into the study of which 377 (97.2%) were included in analyses. The majority of mothers slept under bed nets at home (95.8%) and wore long-sleeved clothes (83.8%) for malaria prevention. However, knowledge of malaria was limited: 44.6% were aware of malaria symptoms, 40.6% knew the malaria transmission route precisely, and 29.2% knew of mosquito breeding places. Staying overnight at a farm hut was significantly associated with having fever during the most recent pregnancy (adjusted odds ratio [AOR] 2.008, 95% confidence interval [CI]: 1.215–3.321) and a child having fever (AOR 3.681, 95% CI 1.943–6.972). Mothers’ partaking in a variety of malaria preventive actions was protective against fever in children (AOR 0.292, 95% CI: 0.136–0.650). Among those who had fever during pregnancy, 39.4% did not seek treatment. Conclusion Although the majority of mothers took malaria preventive actions, knowledge of malaria epidemiology and vector ecology and treatment-seeking behavior for fever were limited. Staying overnight at farm huts, regardless of the differences in socio-demographic and socio-cultural characteristics, was strongly associated with fever episodes during pregnancy and childhood. This study indicates the necessity of spreading accurate malaria knowledge, raising awareness of health risks related to agricultural practices, and promoting treatment-seeking behavior among ethnic minorities to strengthen their engagement in malaria elimination.

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
Flying foxes belonging to the genus Pteropus are known to be reservoirs of zoonotic viruses. In this study, we describe the isolation of Pteropine orthoreovirus (PRV) from rectal swab samples of Pteropus vampyrus in Indonesia. PRV is an emerging zoonotic respiratory virus that can be transmitted from bats to humans. Rectal swabs (n = 91) were screened by PCR for PRV and 10 (11%) were positive. Phylogenetic analysis based on nucleotide sequences indicated that the S2, S3, S4, M3, L2, and L3 segments of one isolate (Garut-69) were closely related to previously isolated strains in Indonesia. The remaining gene segments showed both similarity and genetic divergence with other PRV strains, suggesting that re-assortment events had occurred. This is the first report of PRV infection to P. vampyrus in West Java, Indonesia.

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
In this study, the SureSelect target enrichment system for Illumina Multiplexed Sequencing was applied to proviral DNA sequencing of bovine leukemia virus (BLV). The complete genomic DNA sequences of four Vietnamese BLV strains were successfully obtained with high read depth values and a genome coverage of 100% across all sequenced samples, in less than one week. This study provides the first complete Vietnamese BLV genome sequences. Their genetic variability and phylogenetic relationship were also analyzed and compared with those of 28 whole BLV genome sequences from different parts of the world. The results obtained provided new insights into the genetic diversity of the BLV tax gene, and further enabled us to identify nucleotide mutations in the gene that might not have been detected with the commercial detection kit that is currently available.

Abstract
Bovine abortion, diarrhea, and respiratory disease complexes, caused by infectious agents, result in high and significant economic losses for the cattle industry. These pathogens are likely transmitted by various vectors and reservoirs including insects, birds, and rodents. However, experimental data supporting this possibility are scarce. We collected 117 samples and screened them for 44 bovine abortive, diarrheal, and respiratory disease complex pathogens by using Dembo polymerase chain reaction (PCR), which is based on TaqMan real-time PCR. Fifty-seven samples were positive for at least one pathogen, including bovine viral diarrhea virus, bovine enterovirus, Salmonella enterica ser. Dublin, Salmonella enterica ser. Typhimurium, and Neospora caninum; some samples were positive for multiple pathogens. Bovine viral diarrhea virus and bovine enterovirus were the most frequently detected pathogens, especially in flies, suggesting an important role of flies in the transmission of these viruses. Additionally, we detected the N. caninum genome from a cockroach sample for the first time. Our data suggest that insects (particularly flies), birds, and rodents are potential vectors and reservoirs of abortion, diarrhea, and respiratory infectious agents, and that they may transmit more than one pathogen at the same time.

Abstract
The intestinal microbiota was revealed with the recent advances in molecular techniques, such as high-throughput sequencing analysis. As a result, the microbial changes are thought to
influence the health of humans and animals and such changes are affected by several factors including diet, genetics, age, sex, and diseases. Similar studies are being conducted in dogs, and
the knowledge of intestinal microbiota in dogs is expanding. Nonetheless, basic information on intestinal microbiota in dogs is less than that of humans. Our aim was to study toy poodles
(n=21), a popular companion dog, in terms of basic characteristics of the faecal microbiota by 16S rRNA gene barcoding analysis. In the faecal microbiota, Firmicutes, Bacteroidetes,
Proteobacteria, and Fusobacteria were the dominant phyla (over 93.4% of faecal microbiota) regardless of the attributes of the dogs. In family level, Enterobacteriaceae, Bacteroidaceae, and
Lachnospiraceae were most prevalent. In case of a dog with protein-losing enteropathy, the diversity of faecal microbiota was different between before and after treatment. This study
provides basic information for studying on faecal microbiota in toy poodles.

Abstract
Background Maternal morbidity and mortality is still a major public health issue in low- and middle-income countries such as Cambodia. Improving access to antenatal care (ANC) services for pregnant women has been widely recognized as one of the most effective means of reducing maternal mortality and morbidity. As such, this study examined the barriers for pregnant women living in rural, agricultural villages to accessing ANC based on data collected in the Ratanakiri province, one of the least developed provinces in Cambodia, using a combination of a community-based cross-sectional survey and a geographic information system (GIS). Methods A community-based cross-sectional survey was conducted among 377 mothers with children under the age of two living in 62 villages in the Ratanakiri province, Cambodia, in December 2015. Face-to-face interviews were conducted to ask mothers about their ANC service use, knowledge of ANC, barriers to accessing health facilities, and complications they experienced during the most recent pregnancy. At the same time, GIS data were also collected using a Global Positioning System (GPS) to accurately measure actual travel distance of pregnant women to access health facilities and to examine geographical and environmental barriers in greater detail. Results Only a third of the mothers met the recommendations made by the World Health Organization (WHO) of receiving ANC four times or more (achieved ANC4+), and a quarter of the mothers had never received ANC during their most recent pregnancy. Factors positively associated with achieving ANC4+ were mother’s secondary or higher education (adjusted odds ratio [AOR] = 5.50, 95% confidence interval [CI]: 1.74, 17.37), being aware that receiving ANC is recommended (AOR = 2.74, 95% CI: 1.25, 6.00), and knowledge about the recommended frequency for ANC (AOR = 2.26, 95% CI: 7.22). Actual travel distance was negatively associated with achieving ANC4+. Mothers who had to travel 10.0–14.9 km were 68% less likely (AOR = 0.32, 95% CI: 0.10, 0.99), and those who had to travel 15.0 km or longer were 79% less likely (AOR = 0.21, 95% CI: 0.07, 0.62) to have achieved ANC 4+, both compared to those who travelled 5.0 km or less. While most previous studies have used a straight-line to measure distance traveled, this study much more accurately measured the actual distance traveled by using a GIS. As a result, there was a statistically significant discrepancy between actual travel distance and straight-line distance. Conclusions This study revealed promoting factors and barriers for ANC use among pregnant women living in remote, agricultural villages in Cambodia. Furthermore, this study highlights the importance of measuring travel distances accurately to ensure that targeted interventions for ANC are not misguided by straight-line distances. The methodology used in this study can be applied widely to other developing countries, especially in remote areas with limited road networks where there may be a large discrepancy between actual and straight-line distances.

Abstract
To study the genetic diversity of enterovirus G (EV-G) among Japanese pigs, metagenomics sequencing was performed on fecal samples from pigs with or without diarrhea, collected between 2014 and 2016. Fifty-nine EV-G sequences, which were >5,000 nucleotides long, were obtained. By complete VP1 sequence analysis, Japanese EV-G isolates were classified into G1 (17 strains), G2 (four strains), G3 (22 strains), G4 (two strains), G6 (two strains), G9 (six strains), G10 (five strains), and a new genotype (one strain). Remarkably, 16 G1 and one G2 strain identified in diarrheic (23.5%; four strains) or normal (76.5%; 13 strains) fecal samples possessed a papain-like cysteine protease (PL-CP) sequence, which was recently found in the USA and Belgium in the EV-G genome, at the 2C–3A junction site. This paper presents the first report of the high prevalence of viruses carrying PL-CP in the EV-G population. Furthermore, possible inter- and intragenotype recombination events were found among EV-G strains, including G1-PL-CP strains. Our findings may advance the understanding of the molecular epidemiology and genetic evolution of EV-Gs.

Abstract
VP22 is a major tegument protein of equine herpesvirus type 1 (EHV-1). In the present
study, we examined functions of VP22 in EHV-1 replication by viral protein expression
analyses in cells infected with the VP22-deficient virus. The expressions of several viral
proteins in the cells infected with the VP22-deficient virus were lower than those in the
cells infected with the parent virus. One of the weakly expressed proteins was identified
as ICP4, which is a major regulatory protein encoded by an immediate early gene of EHV-1.
A real-time PCR analysis showed that the mRNA expression of ICP4 was the same in cells
infected with the parent and VP22-deficient viruses. Hence, VP22 appears to promote
synthesis of ICP4 post-transcriptionally.

Abstract
The influenza D virus, a new member of the Orthomyxoviridae family, is predominantly found in cattle. Although viral pathology and clinical disease in cattle appear mild, this virus plays an important role as a trigger of bovine respiratory disease (BRD). BRD is a costly illness worldwide. Thus, epidemiological surveys of the influenza D virus are necessary. Here, we conducted a molecular epidemiological survey for the influenza D virus in healthy and respiratory-diseased cattle in Japan. We found that 2.1% (8/377) of the cattle were infected with influenza D. The cattle with and without respiratory symptoms had approximately equal amounts of the virus. A full-genome sequence analysis revealed that the influenza D virus that was isolated in Japan formed an individual cluster that was distinct from the strains found in other countries. These results suggest that this virus might have evolved uniquely in Japan over a long period of time and that the viral pathology of Japanese strains might be different from the strains found in other countries. Continuous surveillance is required to determine the importance of this virus and to characterize its evolution.

Abstract
An end-pumped Nd:YVO4 laser under selective pumping is used to excite lasing modes with transverse patterns performed to exhibit the characteristics of multiple spots arranged on elliptical features near degenerate cavities. The spatial distribution of elliptical lasing modes is clearly revealed to be localized on the nonplanar ray orbits, so-called nonplanar elliptical modes, which possess large fractional orbital angular momentum. Moreover, temporal dynamics for the output emission of nonplanar elliptical modes are verified to obtain self-mode-locked operation. We further numerically manifest not only the influence of radial-asymmetry distributions on the vortex structures of nonplanar elliptical modes, but also the vector field of transverse lasing modes altered with twisting phase structures in the propagation direction.

Abstract
Sapoviruses (SaV) are enteric viruses infecting humans and animals. SaVs are highly diverse and are divided into multiple genogroups based on structural protein (VP1) sequences. SaVs detected from pigs belong to eight genogroups (GIII, GV, GVI, GVII, GVIII, GIX, GX, and GXI), but little is known about the SaV genogroup distribution in the Japanese pig population. In the present study, 26 nearly complete genome (>6000 nucleotide: nt) and three partial sequences (2429nt, 4364nt, and 4419nt in length, including the entire VP1 coding region) of SaV were obtained from one diarrheic and 15 non-diarrheic porcine feces in Japan via a metagenomics approach. Phylogenetic analysis of the complete VP1 amino acid sequence (aa) revealed that 29 porcine SaVs were classified into seven genogroups; GIII (11 strains), GV (1 strain), GVI (3 strains), GVII (6 strains), GVIII (1 strain), GX (3 strains), and GXI (4 strains). This manuscript presents the first nearly complete genome sequences of GX and GXI, and demonstrates novel intergenogroup recombination events.

Abstract
Fur seal feces-associated circular ssDNA virus (FSfaCV) was discovered in a pig for the first time in Japan using a next-generation sequencer with duplex-specific nuclease. Full genome of the virus showed approximately 92% similarity to FSfaCVs from New Zealand fur seals. Furthermore, we investigated the prevalence of the ssDNA virus in 85 piglets in Japan, and 65 piglets were positive (76%) for the virus.

Abstract
A 33-month old, neutered female Abyssinian cat died. The cat had sudden onset of widespread neurologic signs about half a year after birth. Mycobacterium avium subsp. hominissuis (MAH) group was isolated and identified from the brain of a cat affected with pyogranulomatous meningoencephalitis. The central nervous system (CNS) was involved in the disseminated MAH infection. MAH infection should be considered in cats with neurologic signs in regard to zoonotic aspects. Comparatively, this is a first case of MAH infection observed in the brain in either humans or animals.

Abstract
Porcine astroviruses (PoAstVs) are ubiquitous enteric virus of pigs that are distributed in several countries throughout the world. Since PoAstVs are detected in apparent healthy pigs, the clinical significance of infection is unknown. However, AstVs have recently been associated with a severe neurological disorder in animals, including humans, and zoonotic potential has been suggested. To date, little is known about the epidemiology of PoAstVs among the pig population in Japan. In this report, we present an analysis of nearly complete genomes of 36 PoAstVs detected by a metagenomics approach in the feces of Japanese pigs. Based on a phylogenetic analysis and pairwise sequence comparison, 10, 5, 15, and 6 sequences were classified as PoAstV2, PoAstV3, PoAstV4, and PoAstV5, respectively. Co-infection with two or three strains was found in individual fecal samples from eight pigs. The phylogenetic trees of ORF1a, ORF1b, and ORF2 of PoAstV2 and PoAstV4 showed differences in their topologies. The PoAstV3 and PoAstV5 strains shared high sequence identities within each genotype in all ORFs; however, one PoAstV3 strain and one PoAstV5 strain showed considerable sequence divergence from the other PoAstV3 and PoAstV5 strains, respectively, in ORF2. Recombination analysis using whole genomes revealed evidence of multiple possible intra-genotype recombination events in PoAstV2 and PoAstV4, suggesting that recombination might have contributed to the genetic diversity and played an important role in the evolution of Japanese PoAstVs.

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
Bovine respiratory disease complex (BRDC) is frequently found in cattle worldwide. The etiology of BRDC is complicated by infections with multiple pathogens, making identification of the causal pathogen difficult. Here, we developed a detection system by applying TaqMan real-time PCR (Dembo respiratory-PCR) to screen a broad range of microbes associated with BRDC in a single run. We selected 16 bovine respiratory pathogens (bovine viral diarrhea virus, bovine coronavirus, bovine parainfluenza virus 3, bovine respiratory syncytial virus, influenza D virus, bovine rhinitis A virus, bovine rhinitis B virus, bovine herpesvirus 1, bovine adenovirus 3, bovine adenovirus 7, Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, Trueperella pyogenes, Mycoplasma bovis and Ureaplasma diversum) as detection targets and designed novel specific primer-probe sets for nine of them. The assay performance was assessed using standard curves from synthesized DNA. In addition, the sensitivity of the assay was evaluated by spiking solutions extracted from nasal swabs that were negative by Dembo respiratory-PCR for nucleic acids of pathogens or synthesized DNA. All primer-probe sets showed high sensitivity. In this study, a total of 40 nasal swab samples from cattle on six farms were tested by Dembo respiratory-PCR. Dembo respiratory-PCR can be applied as a screening system with wide detection targets.
