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.

Multifactor analysis of variance was followed by Student-Newman-Keuls tests. Individual blood culture bottles were removed from the automated blood culture systems when growth was detected and time to detection was recorded. Fifty clinical isolates of Candida were used in this study, including 10 isolates of each of the following species: Open in a separate window.

It is therefore important to also look at the overlap of missed isolates to determine if there were any missed episodes of simulated candidemia.

National Center for Biotechnology InformationU. The ability of bbactec blood culture systems to detect growth of NAC species has not been thoroughly evaluated.

Growth was detected in all BacT and Bactec mycology bottles, all BacT aerobic bottles, and by terminal subculture of all bottles. This unique medium contains bactdc lysing agent to lyse both red and white blood cells, releasing any intracellular organisms.

Abstract A direct comparison of two automated blood culture systems was conducted to compare their ability to detect Candida growth.

BD BACTEC™ Blood Culture Media – BD

Murray1 Linda S. Do you like this? The growth requirements and characteristics may be different than C. A review of the literature revealed that, in addition to our previous observations, other authors have described a similar phenomenon with regard to recovery of Candida spp. We therefore performed this study to directly compare the ability of two bactc blood culture systems in the detection of the five most common species implicated in candidemia, specifically evaluating growth detection, time to growth detection, and the utility of terminal subcultures with a simulated candidemia model.

If the incubation period were decreased to only 3 days, two more episodes of C. Controlled clinical comparison of three commercial blood culture systems.

Author information Article notes Copyright and License information Disclaimer. After all, as long as one bottle bactfc a standard aerobic and anaerobic blood culture set detects Candida growth, the clinician will 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 expensive than an aerobic or anaerobic blood culture bottle. Mean time to growth detection of C. Blood culture bottles in which no growth was detected were removed from the automated system after 12 days, seven days after the last bottle had growth detected in either automated blood culture system.


However, when only standard aerobic and anaerobic media were used, the BacT performed better than the Bactec in overall growth detection, time to growth detection, and number of false-negatives. It is used for detecting the amount of bacterial contamination in platelet concentrates.

The six different blood culture bottles were each inoculated with 1, yeasts per bottle and then incubated in the corresponding automated system. The predominant cause of candidemia had been C. Controlled clinical laboratory comparison of two supplemented aerobic and anaerobic media used in automated blood culture systems 92240 detect bloodstream infections.

Bactec Blood Culture System, BD Bactec

The mean time to growth detection of C. The aerobic, anaerobic, and mycology media for each system were evaluated: This article has been cited by other articles in PMC. Therefore, time to detection of Candida growth is an important consideration.

A prospective observational study of candidemia: 92400 BacT system missed no episodes of candidemia. Our patented BD BACTEC resin media have been shown to effectively neutralize a wide variety of antibiotics, allowing growth of microorganisms that may not occur with conventional media.

The BacT system missed no episodes of candidemia, even with the above criteria. Harrison2 and Duane R. Nosocomial hactec infections in United States hospitals: A suspension of each specimen was made in 5 ml of normal saline and adjusted to a 0. A closer review of the data also reveals an important finding.

Most of the Candida spp. Recall, though, that our isolates were all incubated for a total of 12 days.
