A case of cronobacter (Enterobacter sakazakii) bacteremia in a breastfed infant

Abstract

Cronobacter multispecies complex (Cronobacter) is a member of the Enterobacteriaceae family that was described as a new genus in 2007 [1].Consumption of contaminated powdered infant formula (PIF) has been associated with invasive Cronobacter infection in infants [1, 2]. The Food and Agricultural Organization and World Health Organization expert consultations in 2004 and 2006 concluded that Cronobacter contamination of PIF did cause infection and disease in infants [2]. Although the presence of Cronobacter in PIF is well documented, the nature of this organism may lead to exposure through other sources [1, 3]. Our case illustrates a rare example of Cronobacter bacteremia in an exclusively breastfed infant of a healthcare worker.
