Valuable of terminal subcultures from negative BACTEC blood culture bottles.
Terminal subcultures from 5,354 negative BACTEC blood culture bottles did not significantly improve the detection of positive cultures. Only 15 of the 545 total isolates were recovered from the terminal subcultures. All 15 of these isolates were either considered contaminants or had been previously detected.
متن کاملMulticenter comparison of BACTEC 9050 and BACTEC 9240 blood culture systems.
The overall recovery of organisms and time to detection with the BACTEC 9050 and BACTEC 9240 systems were compared in a multicenter evaluation. In the first phase of the study, a total of 4,383 compliant aerobic (Plus Aerobic/F) blood culture sets were processed. There was no significant difference in the recovery of individual groups of organisms with the two systems, with the exception of Str...
متن کاملComparison of BACTEC 9240 Peds Plus medium and isolator 1.5 microbial tube for detection of Brucella melitensis from blood cultures.
The sensitivity and time to detection of Brucella melitensis by the BACTEC 9240 and the Isolator blood culture systems were compared in a prospective volume-controlled study. Blood sample aliquots, obtained from children with suspected brucellosis, were inoculated into a BACTEC 9240 Peds Plus bottle and into an Isolator 1.5 Microbial Tube. Overall, 122 pairs of blood samples for culture were ob...
متن کاملLack of requirement for blind subcultures of BACTEC blood culture media.
To determine the need for blind subculturing of BACTEC (Johnston Laboratories, Cockeysville, Md.) blood culture media, we compared results of radiometric readings, visual inspection, and blind subculturing for nearly 7,500 blood specimens. Visual inspection and radiometric testing were performed on day 1 through 7, and blind subcultures were made on day 3. In the first phase of the study, 402 o...
متن کاملPerformance of a BACTEC nonradiometric medium for pediatric blood cultures.
A BACTEC aerobic nonradiometric medium, PEDS Plus, designed for diagnosis of pediatric bacteremia was evaluated in three hospital centers. Equivalent blood volumes (up to 5 ml) were inoculated into and incubated in BACTEC NR-6A (6A) and PEDS Plus broths. Among 4,581 compliant sets, 289 clinically significant organisms, representing more than 20 bacterial and two Candida species, were isolated. ...
