Cronobacter sakazakii ( Syn. : Enterobacter sakazakii . Farmer et al 1980) is a bacterial type of the family Enterobacteriaceae and is a gram-negative bacteria. Cronobacter sakazakii is rod-shaped and motile by flagella. A characteristic feature is the yellow pigmentation of the bacterial cultures .

Cronobacter sakazakii can cause blood poisoning ( sepsis ), meningitis and necrotizing enterocolitis , a dangerous bowel disease, in infants . The rarely occurring infection can occur through baby food, as Cronobacter sakazakii was found in milk powder. Little is known about the bacterium's occurrence and way of life in the wild.

In the English literature, Cronobacter sakazakii is often found under the name "Yellow-Pigmented Enterobacter cloacae ".

Taxonomy

Due to taxonomic advances, the species was transferred to a new genus Cronobacter gen. Nov. posed.
