The disparity of access to suitable social services for people from culturally diverse backgrounds is receiving increased attention. Coproduction between service users and providers has the potential as an approach to improve the cultural responsiveness of social services. What remains unknown is how social service organizations can facilitate and support coproduction with people from culturally diverse backgrounds. This article examines how three disability support organizations in Australia worked with peer support groups run by people with disability and their families from Chinese background to improve the organizations' service provision. We collected qualitative data through observations of activities in the groups and semistructured interviews with group members and organization staff. We found that organizing peer support groups facilitated knowledge exchange between people from culturally diverse backgrounds and organizations to inform practice development. Five contributors to the knowledge exchange were as follows: (1) assigning staff responsibility for exchange and trust with the group; (2) encouraging the group to challenge practice and cultural norms; (3) identifying and supporting the capacity of peer facilitators; (4) fostering trust within the group; and (5) collaborating with other organizations. Cultural responsiveness means incorporating people's cultural preferences in support provision and addressing the negative influences of cultural norms on people.

A novel actinobacterial strain, designated AGMB00827T, was isolated from swine faeces. Strain AGMB00827T was obligately anaerobic, Gram-stain-positive, non-motile, non-spore-forming and rod-shaped bacterium. Comparative analyses based on the 16S rRNA gene and whole genome sequence revealed that strain AGMB00827T was affiliated to the genus Collinsella, and was most closely related to Collinsella vaginalis Marseille-P2666T (= KCTC 25056T). Biochemical analysis showed strain AGMB00827T was negative for catalase and oxidase. Interestingly, strain AGMB00827T possessed urease activity, which was determined by traditional methods (API test and Christensen's urea medium), unlike related strains. Furthermore, the major cellular fatty acids (> 10%) of the isolate were C18:1 ω9c, C16:0, C16:0 DMA and C18:2 ω9,12c DMA. Based on the whole genome sequence analysis, the DNA G + C content of strain AGMB00827T was 52.3%, and the genome size and numbers of rRNA and tRNA genes were 1,945,251 bp, 3 and 46, respectively. The average nucleotide identity and digital DNA-DNA hybridization values between strain AGMB00827T and C. vaginalis KCTC 25056 T were 71.0 and 23.2%, respectively. Additionally, the genome analysis revealed that strain AGMB00827T possesses urease gene cluster including ureABC and ureDEFG while the related strains do not have those genes, which is consistent with the urease activity. On the basis of polyphasic taxonomic approach, strain AGMB00827T represents a novel species within the genus Collinsella, for which the name Collinsella urealyticum sp. nov. is proposed. The type strain is AGMB00827T (= KCTC 25287T = GDMCC 1.2724T).

A Gram-stain-negative, aerobic, non-flagellated and coccoid or ovoid bacterial strain, BSSL-BM11T, was isolated from sand of coastal dunes along the Yellow Sea of the Korean peninsula. Strain BSSL-BM11T grew optimally at 30â°C, at pH 7.0-8.0 and in the presence of 2.0-3.0â% (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences, the up-to-date bacterial core gene set and average amino acid identity (AAI) showed that strain BSSL-BM11T forms a cluster with the type strains of Tianweitania sediminis and Corticibacterium populi. Strain BSSL-BM11T showed 16S rRNA gene sequence similarities of 98.3 and 98.0â% to the type strains of T. sediminis and C. populi, respectively, and less than 96.4â% to the type strains of the other recognized species. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between strain BSSL-BM11T and the type strains of T. sediminis and C. populi were 77.0-84.8â% and 20.0-28.1â%, respectively. The 16S rRNA gene similarity, AAI, ANI and dDDH values between T. sediminis Z8T and C. populi KCTC 42249T were 98.0, 77.4, 76.7 and 20.1â%, respectively. The DNA G+C content of strain BSSL-BM11T from genomic sequence data was 61.3âmol%. Strain BSSL-BM11T contained Q-10 as the predominant ubiquinone and C18â:â1 ω7c, C16â:â0 and cyclo C19â:â0 ω8c as the major fatty acids. The major polar lipids of strain BSSL-BM11T were phosphatidylcholine, phosphatidylglycerol and phosphatidylethanolamine. Based on the polyphasic data, it is proposed that C, populi be reclassified as a member of the genus Tianweitania. Phenotypic and phylogenetic analyses revealed that strain BSSL-BM11T is separated from T. sediminis and C. populi. On the basis of the data presented here, strain BSSL-BM11T (=KACC 21634T=NBRC 114503T) is considered to represent a novel species of the genus Tianweitania, for which the name Tianweitania aestuarii sp. nov. is proposed.

A Gram-negative, obligate anaerobic, non-motile, non-spore-forming, rod-shaped bacterial strain designated AGMB00274T was isolated from swine faeces. An 16S rRNA gene analysis indicated that strain AGMB00274T belonged to the genus Parabacteroides, with the highest similarity to Parabacteroides johnsonii (P. johnsonii) DSM 18315T (sequence similarity of 94.9%). The genome size of strain AGMB00274T was 4,308,683 bp, with a DNA G+C content of 42.5 mol%. The biochemical analysis of strain AGMB00274T showed that it was positive for gelatin hydrolysis and α-fucosidase, but negative for the acid production from D-glucose, D-mannitol, D-maltose, salicin, glycerol, D-cellobiose, D-mannose, D-melezitose, D-sorbitol, D-trehalose, and negative for α-arabinosidase, glutamic acid decarboxylase, and pyroglutamic acid arylamidase. The dominant cellular fatty acids (> 10%) of the isolate were anteiso-C15: 0 (23.2%), iso-C15: 0 (16.6%), C18: 1 ω9c (16.4%), summed feature 11 (iso-C17: 0 3-OH and/or C18: 2 DMA) (12.5%), and C16: 0 (11.3%). The major respiratory quinones of strain AGMB00274T were MK-9 (55.4%) and MK-10 (44.6%). The major polar lipid was phosphatidylethanolamine. Based on phylogenetic, genetic, physiological, and chemotaxonomic analyses, as a novel species of the genus Parabacteroides, strain AGMB00274T was proposed with the name Parabacteroides faecalis sp. nov. The type strain used was AGMB00274T (= KCTC 25286T = GDMCC 1.2742T).

Taxonomic and functional research of microorganisms has increasingly relied upon genome-based data and methods. As the depository of the Global Catalogue of Microorganisms (GCM) 10K prokaryotic type strain sequencing project, Global Catalogue of Type Strain (gcType) has published 1049 type strain genomes sequenced by the GCM 10K project which are preserved in global culture collections with a valid published status. Additionally, the information provided through gcType includes >12 000 publicly available type strain genome sequences from GenBank incorporated using quality control criteria and standard data annotation pipelines to form a high-quality reference database. This database integrates type strain sequences with their phenotypic information to facilitate phenotypic and genotypic analyses. Multiple formats of cross-genome searches and interactive interfaces have allowed extensive exploration of the database's resources. In this study, we describe web-based data analysis pipelines for genomic analyses and genome-based taxonomy, which could serve as a one-stop platform for the identification of prokaryotic species. The number of type strain genomes that are published will continue to increase as the GCM 10K project increases its collaboration with culture collections worldwide. Data of this project is shared with the International Nucleotide Sequence Database Collaboration. Access to gcType is free at http://gctype.wdcm.org/.

A Gram-negative, aerobic, non-flagellated and ovoid or rod-shaped bacterial strain (JHPTF-M18T), which was isolated from a tidal flat sediment in Republic of Korea, was taxonomically characterized. Strain JHPTF-M18T grew optimally at 25 °C, at pH 7.0-7.5 and in the presence of 2.0-3.0% (w/v) NaCl. 16S rRNA gene sequence analysis showed that strain JHPTF-M18T forms a phylogenetic lineage within the radiation comprising type strains of Mesonia species. The 16S rRNA gene of strain JHPTF-M18T shared sequence similarities of 97.7% with that of type strain of M. mobilis and 92.5-96.8% with those of type strains of the other nine Mesonia species. The DNA G+C content was 33.1% based on its genomic sequence. AAI, ANI and dDDH values between strain JHPTF-M18T and the type strains of M. mobilis, M. hitae, M. oceanica, M. phycicola and M. algae were 72.1-83.7%, 73.1-79.7% and 18.5-22.8%, respectively. Strain JHPTF-M18T contained MK-6 as the predominant menaquinone and iso-C15:0, iso-C17:0 3-OH and summed feature 3 (C16:1 ω7c and/or C16:1 ω6c) as its major fatty acids. Major polar lipids of strain JHPTF-M18T were phosphatidylethanolamine and two unidentified lipids. Strain JHPTF-M18T was separated from recognized Mesonia species by its phenotypic properties together with the phylogenetic and genetic distinctiveness. Based on data presented in this study, strain JHPTF-M18T is considered to represent a novel species of the genus Mesonia. The name Mesonia aestuariivivens sp. nov. is proposed for JHPTF-M18T (=KACC 22185T = NBRC 115119T).

A Gram-negative, motile, rod-shaped, aerobic bacterial strain CAU 1632T was isolated from a seawater sample collected in the Republic of Korea. The cells of strain CAU 1632T grew optimally at 30 °C and pH 7.0 in 0% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CAU 1632T formed a tight phyletic lineage with Zhongshania antarctica ZS-23T, Zhongshania borealis CL-AS9T, Zhongshania marina DSW25-10T, Zhongshania guokunii ZS6-22T, 'Zhongshania ponticola GM-8T', Zhongshania aliphaticivorans SM-2T and shared a high similarity between 97.2% and 97.7%. The whole genome of strain CAU 1632T was 4.3-Mb with 3,780 protein-coding genes, 12 contigs, and a DNA G+C content of 49.4 mol%. The major fatty acids of strain CAU 1632T were C17:1 ω8c, C19:1 ω6c and/or C19:0 cyclo ω10c (summed feature 3), and C18:1 ω6c and/or C18:1 ω7c (summed feature 8). Q-8 was the only respiratory quinone. The polar lipids were composed of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two aminophospholipids, and two phospholipids. Based on the results of phenotypic, chemotaxonomic, and phylogenetic analyses, strain CAU 1632T represents a novel species within the genus Zhongshania, for which the name Zhongshania aquimaris sp. nov. is proposed. The type strain is CAU 1632T (= KCTC 82432T = MCCC 1K06086T).
