The average nucleotide identity values of Ko6 with K. oxytoca and K. michiganensis were 91.2 and 93.47 %, respectively. The inability to metabolize melezitose differentiated most of the Ko6 strains from K. oxytoca and K. michiganensis . Based on its genetic and phenotypic characteristics, we propose the name Klebsiella grimontii for the Ko6 sequence cluster, with strain 06D021T (=CIP111401T, DSM 105630T) as the type strain. Strains of Klebsiella grimontii were isolated from human blood cultures, wound infections, antibiotic-associated haemorrhagic colitis and faecal carriage., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002517
