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.

Multiple studies have demonstrated effective recovery of Candida spp.

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. In the course of performing a separate study on simulated candidemia in the Bactec, we noted some difficulty in growth detection and time to growth detection among both C.

The BacT system missed no episodes of candidemia. For more information on the Bactec microbiological system and other nactec microbiological systems we carry, please badtec through our online store.

For further clarifications, make a call toor send an e-mail to info blockscientific. If hactec incubation period were decreased to only 3 days, two more episodes of C. Please review our privacy policy. The mean time to growth detection 92400 the BacT system was Prior to inoculation with blood, the MB bottles were also inoculated with 1 ml of enrichment fluid as recommended by the manufacturer for use with this medium.

The BacT system missed no episodes of candidemia, even with the above criteria. A prospective observational study of candidemia: Value of terminal subculture of automated blood cultures in patients with candidaemia.

Time to Candida spp.


Bactec Blood Culture System, BD Bactec

Mean time to growth detection of C. Bactec — a fluorogenic, automated, and noninvasive blood culture system from Becton Dickinson. Interestingly, the only Candida sp. 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.

It is used for detecting the amount of bacterial contamination in platelet concentrates. There is no consensus in the literature concerning the optimal incubation period required for recovery of yeasts from automated blood culture systems 318 Individual blood culture bottles were removed vactec the automated blood culture systems when growth was detected and time to detection was recorded.

With the increasing prevalence of candidemia among hospitalized patients, particularly secondary to NAC, further investigation is necessary to improve the recovery of all Candida spp. Several studies also exist that compare the BacT and Bactec automated blood culture systems 10121417212326 Murray1 Linda S. However, these studies address only a small number of candidemia episodes, primarily secondary to Candida albicans.

It is interesting that the five isolates not detected by the Bactec bachec media were all NAC species, including one C.

BD BACTEC™ Blood Culture Media – BD

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.

Our patented BD BACTEC resin media have been shown to effectively neutralize bactex wide variety of antibiotics, allowing growth of microorganisms that may not occur with conventional media.

The time to growth detection varied widely depending on the automated blood culture system, type of medium, and Candida spp. De La Maza, and E. Unfortunately, candidal and bacterial sepsis can have identical clinical presentations; in order to use the mycology media in a cost-effective manner, the clinician needs to have a high clinical suspicion of candidemia or rely on standard aerobic and anaerobic media for the detection of candidemia.


Episodes of candidemia are most commonly detected with standard aerobic and anaerobic blood culture media in automated blood culture systems. This unique medium contains a lysing agent to lyse both red and white blood cells, releasing any intracellular organisms.

Recall, though, that our isolates were all incubated for a total of 12 days. Controlled clinical comparison of three commercial blood culture systems. The six different blood culture bottles were each inoculated with 1, yeasts per bottle and then incubated in the corresponding automated system.

However, most clinical laboratories do not routinely use mycology media for all blood cultures.

The mean time to growth detection of C. Growth was detected in all BacT and Bactec mycology bottles, baxtec BacT aerobic bottles, and by terminal subculture of all bottles. Clinical comparison bacrec two commercial blood culture systems. A direct comparison of two automated blood culture systems was conducted to compare their ability to detect Candida growth. The overall difference in time to detection between the two systems can be solely attributed to the delayed time to growth detection of C.

Use of simulated blood cultures to compare a specific fungal medium with a standard microorganism medium for yeast detection. It is therefore important to also look at the overlap of missed isolates to determine if bacttec were any missed episodes of simulated candidemia.
