Coprobacter fastidiosus gen. nov., sp. nov., a novel member of the family Porphyromonadaceae isolated from infant faeces Shkoporov, Andrei N. and Khokhlova, Ekaterina V. and Chaplin, Andrei V. and Kafarskaia, Lyudmila I. and Nikolin, Alexei A. and Polyakov, Vladimir Yu. and Shcherbakova, Victoria A. and Chernaia, Zoya A. and Efimov, Boris A.,, 63, 4181-4188 (2013), doi = https://doi.org/10.1099/ijs.0.052126-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= A novel obligately anaerobic, non-spore-forming, rod-shaped, non-motile Gram-reaction-negative bacterium was isolated from infant faeces. The strain, designated NSB1T, was able to grow on rich media at 30–37 °C, in the presence of up to 2 % (w/v) Oxgall and 2 % (w/v) NaCl. Cells of strain NSB1T produced catalase, but not urease and indole. Aesculin was not hydrolysed. The strain was able to utilize d-glucose, lactose, maltose, mannose and raffinose as electron donors. When grown on d-glucose, the main metabolic end products were propionic and acetic acids, with a minor product being succinic acid. The major cellular fatty acids, iso-C15 : 0 and anteiso-C15 : 0, were present at a 1 : 1 molar ratio. The major menaquinone was MK-11. The DNA G+C content was found to be 38.5 mol%. According to 16S rRNA gene sequence analysis strain NSB1T is a member of the family Porphyromonadaceae , phylum Bacteroidetes . The closest relatives of the strain were Barnesiella viscericola (88.2 % identity) and Barnesiella intestinihominis (87.4 % identity). On the basis of phenotypic and genotypic properties of strain NSB1T we conclude that this strain represent a novel species in a new genus within the family of Porphyromonadaceae for which the name Coprobacter fastidiosus gen. nov., sp. nov. is proposed. The type strain of the species is NSB1T ( = DSM 26242T, = VKM B-2743T)., language=, type=
