Abstract
We have performed experimental studies to compare rates and time of positive blood culture in two culture systems. Each system had different antibiotic absorbents; BACTEC 9000 system/96F, 97F bottle-resin absorbent (Becton Dickinson) and Bact/Alert 120 system/FAN bottle-active carbon absorbent (Organon Technica). Eighteen groups were consisted of 6 bacterial and 1 fungal species and 10 antibiotics. Detection rates and time to positive cultures showed significant differences according to culture system and bottle. Antibacterial absorbents could not reveal perfect activities for some antibiotics and then blood samples should be taken at the time of low blood levels.
