BACTEC™ // I. PRINCIPLE. The detection of microorganisms in a patient’s blood has diagnostic and prognostic importance. Bactec Plus blood culture bottles were preincubated at 35°C or at room temperature before entry into the Bactec instrument to determine the influence of. The overall recovery of organisms and time to detection with the BACTEC and BACTEC systems were compared in a multicenter.

Three of the six types of media were able to detect growth of all 50 Candida isolates. A direct comparison of two automated blood culture systems was conducted to compare their ability to detect Candida growth.
Bactec Automated Blood Culture System Bactec — a fluorogenic, automated, bactdc noninvasive blood culture system from Becton Dickinson. The aerobic detection of C.
Bactec Blood Culture System, BD Bactec
Episodes of candidemia are most commonly detected with standard aerobic and anaerobic blood culture media in automated blood culture systems. Our patented BD BACTEC resin media nactec been shown to effectively neutralize a wide variety of antibiotics, allowing growth of microorganisms that may not occur with conventional media. After all, as long as one bottle of a standard aerobic and anaerobic blood culture set detects Candida growth, the clinician 92400 be able to treat the patient appropriately.
Additionally, the routine use of mycology media adds a substantial expense; each mycology bottle is approximately three times more bxctec than an aerobic or anaerobic blood culture bottle. The ability of automated blood culture systems to detect growth of NAC species has not been thoroughly evaluated.
Multifactor analysis of variance was followed by Student-Newman-Keuls tests. The views expressed are those of the authors and do not reflect the official policy or position of the Department of the Army, Department of Defense, or the U. However, few institutions routinely utilize a mycology bottle as a part of all blood culture sets, secondary to the requirement for extra blood and laboratory space.
The overall difference in time to detection between the two systems can be solely attributed to the delayed time to growth detection of C. However, most clinical laboratories do not routinely use mycology media for all blood cultures. This protocol was approved by the institutional review board at Brooke Army Medical Center. It is interesting that the five isolates not detected by the Bactec aerobic media were all NAC species, including one C. Until improvements in these systems are made, we may need to encourage clinical microbiology laboratories to routinely use mycology media and terminally subculture negative bottles to ensure that episodes of candidemia are not missed.

This greater recovery leads to more accurate diagnosis and effective treatment, which can in turn lead to shorter hospital stays, lower patient costs, and greater overall laboratory and institutional efficiency.

Mean time to growth detection of C. There is no consensus in the literature concerning the optimal incubation period required for recovery of yeasts from automated blood culture systems 318 Is it actually important for both the aerobic and anaerobic media to detect Candida growth?

All aerobic and anaerobic bottles were inoculated with 10 ml of blood, while mycology bottles were inoculated with 5 ml of blood, per the manufacturer’s recommendations.
