Cronobacter is a genus of Gram-negative, facultatively-anaerobic, oxidase negative, catalase positive, rod-shaped bacteria of the family Enterobacteriaceae. They are generally motile, reduce nitrate, utilize citrate, hydrolyze esculin and arginine, and are positive for L-ornithine decarboxylation. Acid is produced from D-glucose, D-sucrose, D-raffinose, D-melibiose, D-cellobiose, D-mannitol, D-mannose, L-rhamnose, L-arabinose, D-trehalose, galacturonate and D-maltose. Cronobacter are also generally positive for acetoin production (Voges–Proskauer test) and negative for the methyl red test indicating 2,3-butanediol rather than mixed acid fermentation. The type species of the genus Cronobacter is Cronobacter sakazakii
Cronobacter was first proposed as a new genus in 2007 as a clarification of the taxonomic relationship of the biogroups found among strains of Enterobacter sakazakii. This proposal was validly published in 2008 with 5 species and 3 subspecies named
