Description of sp. nov., isolated from human rectal swabs and stool samples.

Nine independent Gram-negative bacterial strains were isolated from rectal swabs or stool samples of immunocompromised patients from two different wards of a university hospital. All isolates were phylogenetically analysed based on their 16S rRNA gene sequence, housekeeping gene , multilocus sequence analysis of concatenated partial , , and sequences, and by whole genome sequencing data. The analysed strains of the new species cluster together and form a separate branch with NBRC105721 as the most closely related species. An average nucleotide identity value of 95.9-96% and computation of digital DNA-DNA hybridization values separate the new species from all other type strains of the genus . Biochemical characteristics further delimit the isolates from closely related type strains. As a result of the described data, a new species is introduced, for which the name sp. nov. is proposed. The type strain is Tue2-1 with a G+C DNA content of 52.2 mol%.
