BACTEC 9240 PDF

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.

All were determined to be false-negatives upon terminal subculture. A direct comparison of two automated blood culture systems was conducted to compare their ability to detect Candida growth. Value of terminal subculture of automated blood cultures in patients with candidaemia. Terminal subculture was performed on all 65 of the bottles that had no growth detected nactec the automated blood culture systems; all of these cultures demonstrated heavy growth of pure yeast colonies, representing 65 false-negatives.

Terminal subculture was performed on all bottles in which no growth was detected; a 0. Fifty clinical isolates of Candida were used in this study, including 10 isolates of each of the following species: Aerobic, anaerobic, and mycology media were evaluated in each automated blood culture system.

After the addition of 0. 2940, 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. This potentially poses a problem for many American hospitals where C.

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.

It is therefore important to also look at the overlap of missed isolates to determine if there were any missed episodes of simulated candidemia. The mean bactsc to growth detection of C.

Bactec Blood Culture System, BD Bactec

The BacT system missed no episodes of candidemia. The BD Bactec system can accept test bactef, and comes complete with a rich set of features to provide maximum workflow and productivity. 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.

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. Detection of Candida spp.

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

Secular trends in the epidemiology of nosocomial fungal infections in the United 92440, The views expressed are bachec 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, there is data to suggest that a 3-day incubation period is sufficient for isolation of clinically relevant bacterial and fungal pathogens, and laboratories may adopt a 3-day incubation period in the future 3. Bactec — a fluorogenic, automated, and noninvasive blood culture system from Becton Dickinson.

A suspension of each specimen was made in 5 ml of normal saline and adjusted to a 0. Multiple studies have demonstrated effective recovery of Candida spp.

The overall difference in time to detection between the two systems can be solely attributed to the delayed time to growth detection of C. Author information Article notes Copyright and License information Disclaimer. National Center for Biotechnology InformationU. Both automated blood culture systems detected all episodes of simulated candidemia when specialized mycology media were used. This unique medium contains a lysing agent to lyse both red and white blood cells, releasing any intracellular organisms.

Several studies also exist that compare the BacT nactec Bactec automated blood culture systems 10121417212326 Three of the six types of media were able to detect growth of all 50 Candida isolates.

Individual blood culture bottles were removed from the automated blood culture systems when growth was detected and time to detection was recorded. The ability of automated blood culture systems to detect bactecc of NAC species has not been thoroughly evaluated.

Secular trend of hospital-acquired candidemia among intensive care unit patients in the United States during If a standard 5-day incubation period were employed, the Bactec would have missed an additional episode of C.

Recall, though, that our isolates were all incubated for a total of 12 days. For more information on the Bactec microbiological system and other refurbished microbiological systems we carry, please browse through our online store.
