Precise Species Identification and Taxonomy Update for the Genus Kluyvera With Reporting Kluyvera sichuanensis sp. nov.

ABSTRACT: Kluyvera is a genus within the family Enterobacteriaceae and can cause various human infections but remains poorly studied. A carbapenem-resistant bla _{NDM- 1}-carrying Kluyvera strain 090646^T was isolated from a hospital sink in Chengdu, Sichuan province, China. Whole genome sequencing of the strain revealed that it had 28.2 to 42.3% in silico DNA-DNA hybridization (isDDH) scores and 84.15 to 90.10% average nucleotide identity (ANI) values with other Kluyvera species. Both values are well below the ≥ 70.0% isDDH and ≥ 95-96% ANI cutoffs to define bacterial species, suggesting that the strain represents a novel species of the genus Kluyvera, for which the name Kluyvera sichuanensis. nov. is
