A recent analysis shows that Cronobacter infections in the United States are higher than expected and disproportionately affect infants and elderly adults.
Cronobacter species, formerly known as Enterobacter sakazakii, are gram-negative bacteria thought primarily to cause serious infections in infants. Sepsis and meningitis generally result from Cronobacter infection in infants; some may have seizures. Estimated mortality rates in infants are as high as 80%. In adults, Cronobacter cause septicemia, pneumonia, osteomyelitis, wound infections, and splenic abscesses.
