Abstract

Small, obligately anaerobic strains 13CB8C^T, 13CB11C^T, 13CB18C^T and 13GAM1G^T were isolated from a faecal sample in a patient with Parkinson's disease with a history of duodenal resection. After conducting a comprehensive polyphasic taxonomic analysis including genomic analysis, we propose the establishment of one new genus and four new species. The novel bacteria are Desulfovibrio falkowii sp. nov. (type strain JCM 36128^T = DSM 116810^T), Porphyromonas miyakawae sp. nov. (type strain JCM 36129^T = DSM 116947^T), Mediterraneibacter flintii sp. nov. (type strain JCM 36130^T = DSM 116866^T) and Owariibacterium komagatae gen. nov. sp. nov. (type strain JCM 36131^T = DSM 116982^T), respectively.

Keywords: Desulfovibrio falkowii; Mediterraneibacter flintii; Owariibacterium komagatae; Parkinson’s disease; Porphyromonas miyakawae; human faeces.
