Incidence of Bacteremia in Infants Aged 1 Week to 3 Months

Incidence of bacteremia in previously healthy full-term infants was 2.2%, and Escherichia coli was the most common pathogen.

To evaluate the epidemiology of infant bacteremia, investigators retrospectively analyzed charts of previously healthy full-term infants aged 1 week to 3 months who had undergone blood cultures at a California hospital system from 2005 through 2009. Of 4255 blood cultures, 2.2% were positive for a pathogen and 5.8% were positive for contaminants (coagulase-negative staphylococci, Micrococcus species, and diphtheroids). Pathogens included Escherichia coli (56%), group B Streptococcus (21%), and methicillin-sensitive Staphylococcus aureus (8%). Ten bacteremic patients also had meningitis, and 7 were described as “ill appearing.” There were no cases of Listeria monocytogenes or meningococcemia and only one case of enterococcal bacteremia.
