Members of this species produced indole and ornithine decarboxylase and fermented adonitol but failed to grow in KCN medium. Detectable amounts of hydrogen sulfide were not produced in triple sugar-iron-agar medium but were formed by some strains in peptone-iron-agar. The nomenclature and taxonomic position of these bacteria are discussed, and information that should be helpful for their differentiation from Citrobacter freundii and Enterobacter cloacae is included. Strain 3613–63 (ATCC 27156) is designated as the neotype strain and is described herein. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-22-1-12
