Abstract
One thousand blood specimens were cultured in BACTEC vials containing modified Columbia broth in aerobic, anaerobic, and hypertonic formulations. Radiometric readings and subcultures were performed on aerobic and hypertonic vials at 24 h and 7 days, and on anaerobic vials at 48 h and 7 days. Significant numbers of false-positive BACTEC readings were obtained. Although all positive cultures were eventually detected by the BACTEC, approximately 20% of blood specimens yielding positive subcultures at 24 h did not give positive BACTEC readings until 48 h.
