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.

Use of simulated blood cultures to compare a specific fungal medium with a standard bactc medium for yeast detection. Most of the Candida spp. A closer review of the data also reveals an important finding. There is no consensus in the literature concerning the optimal incubation period required for recovery of yeasts from automated blood culture systems 318 Reference method for broth dilution antifungal susceptibility testing of yeasts; approved standard. Microbiology System — is well suited for use in large laboratories.

Bactec Blood Culture System, BD Bactec

National Committee for Clinical Laboratory Standards. The aerobic, anaerobic, and mycology media for each system were evaluated: Though this may seem adequate, three episodes of candidemia were missed, one C. Please review our privacy policy. The overall difference in time to detection between nactec two systems can be solely attributed to the delayed time to growth detection of C.


Interestingly, the only Candida sp.

The six different blood culture bottles were each inoculated with 1, yeasts per bottle and then incubated in the corresponding automated system. Value of terminal subculture of automated blood cultures in patients with candidaemia.

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.

BD BACTEC™ Blood Culture Media – BD

Fifty clinical isolates of Candida were used in this study, including 10 isolates of each of the following species: All bottles were subcultured and demonstrated heavy growth of pure yeast colonies and were therefore true positives.

Secular trend of hospital-acquired candidemia among intensive care unit patients in the United States during Nosocomial bloodstream infections in United States hospitals: National Center for Biotechnology InformationU. Additionally, the routine use of mycology media adds a substantial expense; each mycology bottle is approximately three times more expensive than an aerobic or anaerobic blood culture bottle.

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. We also thank Walter Mika for assistance with phlebotomy and John A. George1 Clinton K. bacgec


The mean time to growth detection for all Candida spp. Under these circumstances, when only aerobic and anaerobic media are used, the BacT performed better than the BACTEC in overall detection, time to detection, number of false-negatives, and missed episodes of simulated candidemia.

Ward for assistance with statistical analysis of the data.

Bactec 9240 Blood Culture System, BD Bactec 9240

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. The BD Bactec system can accept test bottles, and comes complete with a rich set of features to provide maximum abctec and productivity.

Therefore, time to detection of Candida growth is an important consideration.

The time to growth detection varied widely depending on the automated blood culture system, type of medium, and Candida spp. Each blood culture bottle was inoculated with 92240 blood from healthy donors.
