• The results of 6,951 blood cultures taken from hospitalized children are reviewed. One or more organisms grew from 6% (399) of the cultures, of which 189 (two thirds) were considered to represent confirmed bacteremia. The most common organisms associated with bacteremia were Haemophilus influenzae, Streptococcus pneumoniae, enterobacteriaceae, and Staphylococcus aureus. Patients with deficient host defenses (newborns, oncology patients) with bacteremia had a higher mortality than normal children. Laboratory techniques allowing more rapid detection of positive blood cultures resulted in major alterations in therapy in almost one half of all bacteremic patients.
