Abstract

Strains previously identified as phylogroup Ko6 were characterized by and gene sequencing, genome-sequence based average nucleotide identity analysis and their biochemical characteristics. and sequencing demonstrated that the Ko6 strains formed a well-demarcated sequence cluster related to, but distinct from, (which includes strains previously labelled as phylogroup Ko2) and (Ko1). The average nucleotide identity values of Ko6 with and were 91.2 and 93.47 %, respectively. The inability to metabolize melezitose differentiated most of the Ko6 strains from and . Based on its genetic and phenotypic characteristics, we propose the name for the Ko6 sequence cluster, with strain 06D021 (=CIP111401, DSM 105630) as the type strain. Strains of were isolated from human blood cultures, wound infections, antibiotic-associated haemorrhagic colitis and faecal carriage.
