AbstractA prospective study in pediatric patients compared the BACTEC system, an automated
blood culture system using Bactec Ped Plus/F broth media, with the conventional system using
Brain Heart Infusion broth media. Each single blood sample drawn for culture from hospitalized
children was evaluated by both systems simultaneously. Of 244 pairs of blood samples, 44
( 18%) were positive for microorganisms. Of these isolates, 24 (55%) were detected by both
systems, 10 (23%) were detected by the BACTEC system only, and 10 (23%) were detected by
the conventional system only. The mean turn around time of the BACTEC system (0.56±0.34,
range 0.08-1.55 days) was significantly shorter than that of the conventional system (3.36±
