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...

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...

AIM To compare experience of positive blood cultures in successive years before and after changing from Signal (Unipath) to Bactec 9240 (Becton Dickinson) blood culture systems. METHODS Analysis of data collected prospectively on 7967 Signal and 7062 Bactec blood culture sets. RESULTS Significant growths occurred in 5.7% of Signal and 8.9% of Bactec cultures; 33.0% more significant isolates...

Almost 93% of 97 separate patient isolates of Brucella bloodstream infections were recovered within 5 days of incubation by using the BACTEC 9240 continuous-monitoring blood culturing system.

The effect of immediate incubation of blood cultures at 37°C on the turnaround time and the impact of Gram stain results on antimicrobial management were investigated. During a 6-month period, blood cultures collected at the emergency department outside laboratory operating hours were preincubated at 37°C until transportation to the laboratory. Upon the arrival of blood cultures at the laborato...

Arthritis after plant injury is often apparently aseptic. We report two cases due to Pantoea agglomerans. In one case, the bacterium was isolated only from the pediatric blood culture media, BACTEC Peds Plus, monitored in BACTEC 9240, and not from the other media inoculated with the joint fluid. This procedure could help improve the diagnosis of septic arthritis.

Bordetella pertussis was isolated from a culture of blood from a 31-year-old man with Wegener's granulomatosis. The organism was detected with the BACTEC 9240 system after 6 days of incubation and was confirmed as B. pertussis by the Centers for Disease Control and Prevention. To our knowledge, this is the first published report of the recovery of B. pertussis from blood.
