Answer

Enterobacter infections are most common in neonates and in elderly individuals, reflecting the increased prevalence of severe underlying diseases at these age extremes. In the pediatric ICU setting, an age younger than 2.5 years is a risk factor for colonization.

Enterobacter sakazakii, now known as Cronobacter sakazakii, has been reported as a cause of sepsis and meningitis, complicated by ventriculitis, brain abscess, cerebral infarction, and cyst formation. [15] This clinical pattern appears to be specific to C sakazakii in neonates and infants infected with this bacterium. C sakazakii has also been associated with many outbreaks due to contaminated powdered formula for infants. [16, 17]

The taxonomic reclassification of E sakazakii within a new genus "Cronobacter" within the Enterobacteriaceae was proposed in 2007. [18]
