Abstract
Abstract
Background
Sarcopenia is a geriatric syndrome characterized by loss of muscle mass and muscle function. As the population ages, there is a growing worldwide interest in the intersection of sarcopenia and heart failure (HF). However, estimates of the prevalence of sarcopenia in HF vary widely because of difference in diagnostic criteria. Although the Asian Working Group of Sarcopenia (AWGS) has announced a consensus on the diagnostic criteria of sarcopenia in Asian people, the prevalence and prognostic impact of sarcopenia based on AWGS criteria in patients with HF remains unclear.
Purpose
The aim of this study was to investigate the prevalence and predictive value of sarcopenia identified according to AWGS definition in non-dependent elderly patients with HF.
Methods
This study was a prospective, single-center cohort study in Japan. We consecutively enrolled 274 patients, aged 65 years or older, hospitalized due to acute HF or acute exacerbation of chronic HF and who were able to walk at least 20 m at discharge. Patients with severe cognitive or psychiatric disorders were excluded. Patients with implantable cardiac pacemaker or cardioverter defibrillator were also excluded because skeletal muscle mass was estimated by using bioimpedance analysis. At hospital discharge, we collected data on age, gender, left ventricular ejection fraction, brain natriuretic peptide, estimate glomerular filtration rate, body mass index and sarcopenia. Sarcopenia was diagnosed according to the AWGS criteria: low skeletal muscle index (<7.0 kg/m2 in men, <5.7 kg/m2 in women) and either slow usual walking speed (<0.8 m/s) or low handgrip strength (<26 kg in men, <17 kg in women). Study outcome was rehospitalization for worsening HF within 180 days after discharge. We assessed the independent association between sarcopenia and HF rehospitalization by using multivariate Cox proportional hazards regression analysis.
Results
In this study, a total of 199 patents (43.4%) fulfilled sarcopenia criteria at discharge. During follow-up, 57 patients (20.8%) readmitted for HF. Kaplan-Meier survival curves showed that patients with sarcopenia had significantly lower event-free survival than those without sarcopenia (Figure). After adjusting for other prognostic factors, sarcopenia was independently associated with HF rehospitalization (hazard ratio: 2.31, 95% confidence interval: 1.20–4.53).
Conclusion
Based on AWGS criteria, sarcopenia is highly prevalent even among non-dependent elderly HF patients, and is an independent strong predictor of rehospitalization for worsening HF. AWGS criteria for sarcopenia may be useful for risk prediction in HF.

Abstract
Background A 9-valent human papillomavirus-6/11/16/18/31/33/45/52/58 (9vHPV) vaccine extends coverage to 5 next most common oncogenic types (31/33/45/52/58) in cervical cancer versus quadrivalent HPV (qHPV) vaccine. We describe efficacy, immunogenicity, and safety in Asian participants (India, Hong Kong, South Korea, Japan, Taiwan, and Thailand) from 2 international studies: a randomized, double-blinded, qHPV vaccine-controlled efficacy study (young women aged 16–26 years; NCT00543543; Study 001); and an immunogenicity study (girls and boys aged 9–15 years; NCT00943722; Study 002). Methods Participants (N = 2519) were vaccinated at day 1 and months 2 and 6. Gynecological samples (Study 001 only) and serum were collected for HPV DNA and antibody assessments, respectively. Injection-site and systemic adverse events (AEs) were monitored. Data were analyzed by country and vaccination group. Results 9vHPV vaccine prevented HPV-31/33/45/52/58–related persistent infection with 90.4%–100% efficacy across included countries. At month 7, ≥97.9% of participants seroconverted for each HPV type. Injection-site AEs occurred in 77.7%–83.1% and 81.9%–87.5% of qHPV and 9vHPV vaccine recipients in Study 001, respectively, and 62.4%–85.7% of girls/boys in Study 002; most were mild to moderate. Conclusions The 9vHPV vaccine is efficacious, immunogenic, and well tolerated in Asian participants. Data support 9vHPV vaccination programs in Asia. Clinical Trials Registration NCT00543543; NCT00943722.

Abstract
Previous analyses based on 16S rRNA and hsp60 genes indicated that Parolsenella catena and Libanicoccus massiliensis were closely related to each other and formed a monophyletic cluster independent of the related
Olsenella
species. To clarify the relationship of these two species, we determined the genome sequence of
P. catena
JCM 31932T and compared it with that already sequenced for
L. massiliensis
Marseille-P3237T. Phylogenetic trees based on the concatenated 37 single-copy ribosomal proteins or RpoB robustly supported the relationship observed in the previous studies. Digital DNA–DNA hybridization and average nucleotide identity (ANI) values between
P. catena
JCM 31932T and
L. massiliensis
Marseille-P3237T were 32.6 and 87.8 %, respectively, indicating that
P. catena
JCM 31932T and
L. massiliensis
Marseille-P3237T are independent species. Alignment fraction and ANI values between the two genomes were 0.75 and 88.84 %, respectively, thus indicating that the two species should be classified into the same genus. The number of putative orthologous genes shared between the two genomes was 1321, which was significantly larger than those (482–928) reported between
L. massiliensis
Marseille-P3237T and other closely related species. In addition, the genome of
P. catena
JCM 31932T had a high degree of synteny conservation with that of
L. massiliensis
Marseille-P3237T. On the basis of these findings, we propose that
L. massiliensis
should be reclassified as Parolsenella massiliensis comb. nov.; the type strain is Marseille-P3237T (=JCM 33000T=CCUG 71182T).

Abstract
A taxonomic study of a Gram-stain-positive, rod-shaped, non-motile, non-spore-forming, catalase-negative bacterium, strain YK43T, isolated from spent mushroom substrates stored in Nagano, Japan was performed. Growth was detected at 15–45 °C, pH 5.0–8.5, and 0–10 % (w/v) NaCl. The genomic DNA G+C content of strain YK43T was 43.6 mol%. The predominant fatty acids were C16 : 0, C18 : 1 ω9c and summed feature 8. Based on 16S rRNA gene sequence analysis, the type strains of
Lactobacillus acidipiscis
(sequence similarity, 97.6 %) and
Lactobacillus pobuzihii
(97.4 %) were most closely related to YK43T. The average nucleotide identities were 74.1 % between strain YK43T and
L. acidipiscis
DSM 15836T and 74.0 % between YK43T and
L. pobuzihii
E100301T. Based on a multilocus sequence analysis, comparative genomic analysis and a range of phenotypic and chemotaxonomic characteristics, strain YK43T represents a novel species of the genus
Lactobacillus
, for which the name
Lactobacillus
salitolerans sp. nov. is proposed. The type strain is YK43T (=JCM 31331T = DSM 103433T).

Abstract
In 2016, division of the genus
Propionibacterium
into four distinct genera was proposed. As a consequence, the species
Propionibacterium acnes
was transferred to
Cutibacterium
gen. nov. as
Cutibacterium acnes
comb. nov. The three recently proposed subspecies of
P. acnes
were not, however, accommodated in this proposal. Following a very recent validation of a new combination for
C. acnes
subsp.
defendens
and an automatically created
C. acnes
subsp.
acnes
, we now propose the new combination,
C. acnes
subsp. elongatum comb. nov. The type strain of
Cutibacterium acnes
subsp. elongatum is JCM 18919T (=NCTC 13655T). On the basis of further genomic and phenotypic (haemolysis and MALDI-TOF mass spectrometry) analyses of these subspecies, we also provide emended descriptions of the genus
Cutibacterium
Scholz and Kilian 2016,
C. acnes
subsp.
acnes
(Gilchrist 1900) Nouioui et al. 2018, and

Abstract
Microorganisms are known to exhibit extracellular electron transfer (EET) in a wide variety of habitats. However, as for the human microbiome which significantly impacts our health, the role and importance of EET has not been widely investigated. In this study, we enriched and isolated the EET-capable bacteria from human gut microbes using an electrochemical enrichment method and examined whether the isolates couple EET with anaerobic respiration or fermentation. Upon the use of energy-rich or minimum media (with acetate or lactate) for electrochemical enrichment with the human gut sample at an electrode potential of +0.4 V [vs. the standard hydrogen electrode (SHE)], both culture conditions showed significant current production. However, EET-capable pure strains were enriched specifically with minimum media, and subsequent incubation using the δ-MnO2-agar plate with lactate or acetate led to the isolation of two EET-capable microbial strains, Gut-S1 and Gut-S2, having 99% of 16S rRNA gene sequence identity with Enterococcus avium (E. avium) and Klebsiella pneumoniae (K. pneumoniae), respectively. While the enrichment involved anaerobic respiration with acetate and lactate, further electrochemistry with E. avium and K. pneumoniae revealed that the glucose fermentation was also coupled with EET. These results indicate that EET couples not only with anaerobic respiration as found in environmental bacteria, but also with fermentation in the human gut.

Abstract
OBJECTIVES To examine the ability of different elements of the Self-Feeding Assessment Tool for Elderly with Dementia (SFED) to predict mortality risk in nursing home residents. DESIGN AND SETTING Data from 387 residents in five nursing homes for the elderly in Japan were obtained using a baseline survey. This measure's ability to predict mortality risk was examined over a two-year observation period. Participants and Measurement: Demographic information (sex, age, height, weight, medical history) on 387 initial participants was gathered. A total of 10 individuals were excluded from the analysis because of the inability to eat by mouth at baseline, while 36 were excluded owing to missing mortality data during the observation period. The resulting 341 residents were divided into a death group or survival group according to whether they were still alive after two-year observation period. In addition to basic information and the SFED, the baseline survey included the Barthel Index (BI), Clinical Dementia Rating (CDR), and Mini Nutritional Assessment-Short Form (MNA®-SF). The ability of SFED to predict time-to-event mortality was examined using Cox proportional hazards regression analysis, including other measures associated with mortality as confounding variables. RESULTS In total, 129 participants (37.8%) died during the observation period, and their mean SFED score was significantly lower than that of surviving ones (11.1 ± 6.7 vs. 15.0 ± 5.6, P<0.001). SFED score was significantly associated with two-year mortality in the Cox proportional hazards regression analysis after adjusting for sex, age, medical history, BI, CDR, and MNA®-SF (hazard ratio = 0.941, 95% confidence interval = 0.898-0.985, P = 0.010). Additionally, three SFED categories were significantly associated with mortality risk: movement ("able to eat without dropping food"), concentration ("able to maintain attention to meal"), and safety ("able to swallow without choking, with no change in vocal quality after eating"). CONCLUSIONS Self-feeding ability as measured by SFED score was associated with long-term mortality in elderly living in nursing homes. Accordingly, adjusting feeding assistance based on regular SFED-based assessments may help maintain self-feeding ability and enhance quality of life in this population, as well as providing evidence for end-of-life care options and greatly improving care quality.

Abstract
Two novel, obligately anaerobic, Gram-stain-negative, rod or coccoid-shaped bacteria, designated strains 4NBBH2T and 6FBBBH3T, were isolated from faecal samples of a healthy Japanese woman and man. The 16S rRNA gene sequence analysis showed that these strains represent a distinct lineage within the family Sutterellaceae. Strain 4NBBH2T formed a monophyletic branch between the genera Parasutterella and Sutterella, with sequence similarity to Sutterella stercoricanis CCUG 47620T (92.6 %), followed by Sutterella wadsworthensis WAL 7877 (92.4 %), Sutterella parvirubra YIT 11816T (92.1 %) and Parasutterella secunda YIT 12071T (91.8 %). Strain 6FBBBH3T was affiliated to the genus Sutterella, with highest similarity to S. stercoricanis CCUG 47620T (97.1 %), followed by S. parvirubra YIT 11816T (96.6 %) and S. wadsworthensis WAL 7877 (95.2 %). Strains 4NBBH2T and 6FBBBH3T were asaccharolytic. Analysis of fatty acids revealed that strain 4NBBH2T could be differentiated from Sutterella species (including strain 6FBBBH3T) by the presence of a low concentration of C16 : 1ω7c. The major respiratory quinones of strain 4NBBH2T were menaquinone (MK)-6 and methylmenaquinone (MMK)-6, whereas those of strain 6FBBBH3T were MK-5 and MMK-5. The G+C content of the genomic DNA of strains 4NBBH2T and 6FBBBH3T were 56.9 and 62.8 mol%, respectively. On the basis of the collected data, strain 4NBBH2T represents a novel species in a novel genus of the family Sutterellaceae, for which the name Mesosutterella multiformis gen. nov., sp. nov. is proposed. The type strain is 4NBBH2T (=JCM 32464T=DSM 106860T). We also propose a novel Sutterella species, Sutterellamegalosphaeroides sp. nov., for strain 6FBBBH3T (=JCM 32470T=DSM 106861T).

Abstract
The multi-pass Thomson scattering (MPTS) system is a useful technique for increasing the Thomson scattering (TS) signal intensities and improving the TS diagnostic time resolution. The MPTS system developed in GAMMA 10/PDX has a polarization-based configuration with an image relaying system. The MPTS system has been constructed for enhancing the Thomson scattered signals for the improvement of measurement accuracy and the megahertz sampling time resolution. However, in the normal MPTS system, the MPTS signal intensities decrease with the pass number because of the damping due to the optical components. Subsequently, we have developed a new MPTS system with the laser amplification system. The laser amplification system can improve the degraded laser power after six passes in the multi-pass system to the initial laser power. For the first time worldwide, we successfully obtained the continued multi-pass signals after the laser amplification system in the gas scattering experiments.

Abstract
Azathioprine (AZA) is increasingly being prescribed to rheumatoid arthritis (RA) patients. Following oral administration, AZA is converted into its active form. Inflammatory bowel disease (IBD) and systemic lupus erythematosus (SLE) patients with low thiopurine (S)-methyltransferase (TPMT) activity tend to respond well to AZA therapy. In a previous study of Japanese SLE patients under low-dose AZA therapy, the group with the 94C>A mutation in inosine triphosphatase (ITPA) showed greater improvement in their disease activity index. However, it is not yet clear how genotypes relate to responsiveness to RA treatment. The genotypes ITPA 94C>A, TPMT*3C, NUDT15 595C>T, GST-M1, GST-T1 and MRP4/ABCC4 2269G>A of Japanese patients with RA were determined. The relationship between these genotypes and response to AZA therapy was evaluated using the Disease Activity Score 28 (DAS28) and various medical data. Of the 22 patients 15 had the ITPA 94C/C genotype, 7 had the ITPA 94C/A genotype, none had the TPMT*3C mutation, 4 had the NUDT15 595C>T mutation, 8 had the GST-M1 and T1 null genotypes and 9 had the MRP4/ABCC4 2269G>A mutation. Changes in DAS28 at 6 months after baseline were similar in both ITPA genotype groups. However, the maintenance dose of AZA was significantly lower in the C/A group than in the C/C group (0.85±0.30 mg/kg/day vs. 1.2±0.46 mg/kg/day, respectively; p = 0.043). The ITPA 94C/A group showed the same response to RA treatment as the C/C group, but at a lower dose. This demonstrates that RA patients with the ITPA 94C>A mutation are more responsive to AZA.

Abstract
An obligately anaerobic, Gram-positive, non-spore-forming, straight rod-shaped bacterium, designated strain 3BBH22T, was isolated from a faecal sample of a healthy Japanese woman. The 16S rRNA gene sequence analysis showed that strain 3BBH22T formed a monophyletic cluster with species in the genera Pseudoflavonifractor and Flavonifractor within the family Ruminococcaceae and had highest similarity to Pseudoflavonifractor capillosus ATCC 29799T (96.7 % sequence similarity), followed by Flavonifractor plautii ATCC 29863T (96.4 %). Acetate and butyrate were produced by strain 3BBH22T as metabolic end-products. The major cellular fatty acids were C14 : 0, C16 : 0, C18 : 1ω9c, C16 : 0 dimethyl acetal, C18 : 0 and C18 : 2ω6,9c. No respiratory quinones were detected. In contrast to F. plautii JCM 32125T, strain 3BBH22T did not degrade quercetin, one of the flavonoids. P. capillosus JCM 32126T also did not. Strain 3BBH22T was differentiated from P. capillosus JCM 32126T by its inability to hydrolyse aesculin. The G+C content of the genomic DNA was 61.2±1.0 mol%. On the basis of these data and the phylogenetic tree based on 89 proteins, strain 3BBH22T represents a novel species in a novel genus of the family Ruminococcaceae, for which the name Lawsonibacter asaccharolyticus gen. nov., sp. nov. is proposed. The type strain of L. asaccharolyticus is 3BBH22T (=JCM 32166T=DSM 106493T).

Abstract
Strain 2CBEGH3T, which is an obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-stain-positive coccobacillus, was isolated from a faecal sample of a healthy Japanese man. The 16S rRNA gene sequence analysis showed that strain 2CBEGH3T represented a member of the family Atopobiaceae and formed a monophyletic cluster with Olsenella uli DSM 7084T (93.6 % sequence similarity), Olsenella umbonata strain lac31T (93.0 %), Olsenella profusa JCM 14553T (92.7 %) and Olsenella scatoligenes strain SK9K4T (92.7 %) as closest neighbours and Atopobium species. The hsp60 gene sequence analysis supported the phylogenetic relationships based on the 16S rRNA gene sequences, with sequence similarity values of 82.1-84.7 % to the four species described above. A unique three-base (one amino acid residue) insertion was found in the alignment regions of the hsp60 gene sequence of strain 2CBEGH3T. The major end products from d-glucose were d- and l-lactic acids produced at the ratio of 75 : 25, while four species of the genus Olsenella produced d- and l-lactic acids at ratios of 94-98 : 2-6. The isolate formed characteristic crater-like colonies on Eggerth-Gagnon agar plates. The major cellular fatty acids were C18 : 1ω9c, C18 : 1ω9c dimethyl acetal (DMA) and C16 : 0 DMA. The G+C content of the genomic DNA was 68.4 mol%. On the basis of these data, strain 2CBEGH3T represents a novel species in a novel genus of the family Atopobiaceae, for which the name Parolsenella catena gen. nov., sp. nov. is proposed. The type strain of P. catena is 2CBEGH3T (=JCM 31932T=DSM 105194T).

Abstract
Abstract:This article describes the design and results of implementation of an automated patient registration and freatment allocation system (RETAS) used in multicenter clinical trials. RETAS was developed using a FAX-OCR system by which handwritten Japanese and English characters, as well as numericals and forms with check boxes, are sent from participating institutions by Fax, processed using an optical character reader, and then transmitted to a host computer at a statistical center. Based on the facsimile data, RETAS can automatically review eligibility, collect patient identification data and provide a randomized treatment allocation. RETAS permits uninterrupted, unattended operation at a statistical center, 24 hours a day, 7 days a week. Therefore, it drastically decreases the workload of personnel at the statistical center needed to support central telephone registration coverage. Consequently, staff members are free to focus on patient registration, treatment allocation, and follow-up of patients. The treatment allocation procedure in this system is based on Pocock and Simon’s minimization method combined with Zelen’s method for institution balancing. By this system it was possible to balance treatment numbers for each level of various prognostic factors over an entire trial and, at the same time, balance the allocation of treatments within an institution. The system currently supports the protocol of a clinical trial for Adjuvant Chemo-Endocrine Therapy for Breast Cancer in West Japan.

Abstract
PURPOSE To investigate the aqueous and vitreous penetration of levofloxacin, the drug was administered topically and/or orally to patients undergoing vitrectomy. METHODS Thirty-six patients undergoing initial vitrectomy with phacoemulsification and aspiration (PEA) were enrolled, and were divided randomly into three groups. Group 1 was treated with topical application of levofloxacin (three times on the day before surgery and seven times on the day of surgery), Group 2 received oral administration of levofloxacin (200 mg twice on the day before surgery and 200 mg at 3 hours before surgery), and Group 3 received both topical and oral levofloxacin according to the above schedules. The concentration of levofloxacin was measured in aqueous humor and vitreous fluid samples obtained during surgery. RESULTS In Groups 1, 2, and 3, the mean levofloxacin concentration in aqueous humor was 0.765+/-0.624 micro g/mL, 1.279+/-0.440 micro g/mL, and 1.823+/-0.490 micro g/mL, respectively, while the mean levofloxacin concentration in vitreous fluid was <0.02 micro g/mL, 1.455+/-0.445 micro g/mL, and 1.369+/-0.530 micro g/mL, respectively. CONCLUSIONS Oral administration of levofloxacin at a dose of 400 mg/day was sufficient for the prophylaxis of ocular infections, because the drug concentrations in both aqueous humor and vitreous fluid were higher than the MIC90 values for major ocular pathogens. Topical application of levofloxacin achieved adequate drug levels in aqueous humor, but not in vitreous fluid, while combined topical and oral administration had an additive effect on the drug concentration in aqueous humor.

Abstract
In their natural environments, microorganisms usually live in organized communities. Profiling analysis of microbial communities has recently assumed special relevance as it allows a thorough understanding of the diversity of the microbiota, its behavior over time, and the establishment of patterns associated with health and disease. The application of molecular biology approaches holds the advantage of including culture-difficult and as-yet-uncultivated phylotypes in the profiles, providing a more comprehensive picture of the microbial community. This chapter focuses on two particular techniques, namely, terminal restriction fragment length polymorphism (T-RFLP) and denaturing gradient gel electrophoresis (DGGE), both of which have been widely used in environmental studies and have been successfully used by the authors in the study of the oral microbial communities associated with conditions of health and disease.

Abstract
Background One approach to reducing occupational stress during an economic recession is to share work amongst employees. This may include reducing employees' working hours to avoid redundancies. Aims To examine whether work-sharing influenced the psychosocial work environment and depressive symptoms encountered by Japanese employees, and to determine which psychosocial factors predict employees' mental health during an economic recession. Methods A survey was performed in a Japanese manufacturing company at the beginning (T1) and end (T2) of a 6-month period during the 2008 economic recession using the validated Job Content Questionnaire (JCQ) and Self-Rating Depression Scale (SDS). Results Three hundred and thirty-six male employees completed the questionnaire. Twenty-four per cent of participants showed depressive symptoms at T1. Despite reductions in employees' working hours and job strain (P < 0.001), SDS scores showed no change after 6 months. Logistic regression analyses showed that low social support between the two surveys was associated with depressive symptoms at T2 after adjusting for demographic, lifestyle, workplace factors, scheduled working hours and depressive symptoms at T1. Conclusions Reductions in job strain did not affect employees' depressive symptoms. Employees with low social support during the study had a significantly higher risk of having depressive symptoms. These findings indicate that social and emotional support within the workplace is important during the work-sharing period.

Abstract
BACKGROUND AND PURPOSE Branch atheromatous disease is a stroke subtype considered a risk factor for early neurologic deterioration. Meanwhile, crossed cerebellar diaschisis is thought to be influenced by the degree and location of supratentorial perfusion abnormalities and is associated with the clinical outcome in the case of an ischemic stroke. In this article, our aim was to clarify the utility of using a whole-brain 3D pulsed continuous arterial spin-labeling method as an imaging biomarker for predicting neurologic severity in branch atheromatous disease. MATERIALS AND METHODS Twenty-three patients with branch atheromatous disease in the lenticulostriate artery territory were enrolled. All patients underwent MR imaging, including DWI, 3D-TOF-MRA, and 3D-arterial spin-labeling. We measured the asymmetry index of CBF in the affected area (branch atheromatous disease), the asymmetry index of the contralateral cerebellar hemisphere (crossed cerebellar diaschisis), and the DWI infarct volume in the lenticulostriate artery territory. We also compared each parameter with the initial NIHSS score with the Pearson correlation coefficient. RESULTS Among the 23 patients, we found no correlation between NIHSS score and the asymmetry index of CBF in the affected area (branch atheromatous disease) (r = -0.027, P = .724), whereas the asymmetry index of the contralateral cerebellar hemisphere (crossed cerebellar diaschisis) and DWI infarct volumes were significantly correlated with NIHSS score (r = 0.515, P = .012; r = 0.664, P = .001, respectively). CONCLUSIONS In patients with branch atheromatous disease, 3D-arterial spin-labeling can detect crossed cerebellar diaschisis, which is correlated with the degree of neurologic severity.

Abstract
Two bacterial strains, designated EGH7T and TSAH33, were isolated from human faeces and characterized by using a polyphasic taxonomic approach that included analysis of morphology, phenotypic and biochemical features, cellular fatty acid profiles and phylogenetic position based on 16S rRNA and hsp60 gene sequence analyses. The results of 16S rRNA gene sequence analysis indicated that these strains represented members of the family Lachnospiraceae and formed a monophyletic cluster near Eubacterium contortum JCM 6483T (95 % sequence similarity), Ruminococcus gnavus JCM 6515T (95 %), Clostridium oroticum JCM 1429T (95 %), Eubacterium fissicatena JCM 31501T (95 %) and Clostridium nexile JCM 31500T (94 %). The results of a hsp60 gene sequence analysis supported the phylogenetic tree based on the 16S rRNA gene sequence, with a sequence similarity value of between 77.9 and 84.8 % to the five strains listed above. The novel strains were obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-stain-positive cocco-bacilli. The strains formed characteristic umbilicated colonies on EG agar plates. The major cellular fatty acids were C18 : 1ω9c, C16 : 0 and C18 : 1ω9c dimethyl acetal (DMA). EGH7T and TSAH33 have DNA G+C contents of 46.9 and 45.5 mol%, respectively. On the basis of these data, strains EGH7T and TSAH33 represent a novel species of a novel genus, for which the name Faecalimonas umbilicata gen. nov., sp. nov. is proposed. The type strain of F. umbilicata is EGH7T (=JCM 30896T=DSM 103426T).

Abstract
Whole-genome sequencing was performed for Lactobacillus parakefiri JCM 8573T to confirm its hitherto controversial taxonomic position. Here, we report its first reliable reference genome. Genome-wide
metrics, such as average nucleotide identity and digital DNA-DNA hybridization, and phylogenomic analysis based on multiple genes supported its taxonomic status as a distinct species in the genus Lactobacillus.
The availability of a reliable genome sequence will aid future investigations on the industrial applications of L. parakefiri in functional foods such as kefir grains.

Abstract
The newly developed rapid diagnostic test (RDT, DK14-CA1, Denka Seiken Co., Ltd.) to detect Campylobacter antigen was evaluated using fecal specimens of patients with enteritis. The RDT is an immunochromatographic assay using colored latex and can detect Campylobacter antigen (C. jejuni and C. coli) from patients' stool samples within 15 minutes. A total of 227 stool samples obtained from patients with enteritis were examined and the results were compared with conventional culture methods. Overall sensitivity, specificity, accuracy and positive predictive value (PPV) were 75.6%, 98.6%, 89.9% and 97.0% respectively. Among 53 severe cases defined with their clinical findings, sensitivity, specificity, accuracy and PPV were 82.1%, 100%, 90.6% and 100% respectively. Mean time to obtain the result with the RDT was 7 minutes whereas the culture method took 2.2 days. This study revealed the usefulness of the newly developed RDT as a rapid detection tool for Campylobacter antigen. Although the RDT has a little lower sensitivity compared with culture method, the simple and rapid test can contribute to treatment decisions for patients with enteritis and can be used at the patient's bedside and in outpatient clinics.
