Rapid detection of positive blood cultures with the BACTEC NR-660 does not require first-day subculturing.
An analysis of blood culture data was performed to determine whether subculturing within the first 24 h of incubation decreased the time to detection of positive blood cultures when compared with the routine use of the BACTEC NR-660 system (Johnston Laboratories, Inc., Towson, Md.). During a 9-month period (June 1985 to February 1986), 17,913 blood cultures were received in our laboratory, of w...
متن کاملEvaluation of acridine orange staining as a replacement of subcultures for BacT/ALERT-positive, gram stain-negative blood cultures.
Among 18,424 blood culture sets processed during a study period of 18 months, 85 bottles that were positive by the BacT/ALERT system were Gram stain negative. Both acridine orange staining and subcultures detected microorganisms in a total of 12 bottles. Acridine orange staining can replace subcultures of false-positive blood cultures.
متن کاملComparative study of subculture, Gram staining and acridine orange staining for early detection of positive blood cultures.
In view of the importance of a rapid aetiological diagnosis in septicaemia, we compared the results of subculture, Gram staining and acridine orange staining in the detection of positive blood cultures. The study was based on 1013 blood cultures of which 138 were positive by culture. The three techniques were applied 12 h after the specimen was taken in 210 instances, at 24 h in 540 instances a...
متن کاملComparison of Bactec NR-660 and Signal systems.
Bactec NR-660, a computerised blood culture system using infrared analysis of microbial generated carbon dioxide, was compared with the Signal system, which detects gaseous pressure (due to bacterial metabolism) by a manometer. Four trials were undertaken: an in vitro evaluation of 99 bacteria in simulated blood cultures, and three prospective comparisons of a total of 2588 paired patient sampl...

• Fischer 0., Dagmar Zendulkova: Staining With an Acridine Orange Derivative for the Detection of Mycoplasmas in Cell Cultures. Acta vet. Brno, 62,1993: 49-53. 24 cell cultures were examined for the presence of mycoplasmas by fluorescence methods using 3-amino-6-methoxy-9-(2-hydroxyethylamino) acridine (AMHA) or bisbenzimide 33258 (Hoechst), and by culture in liquid media containing glucose or ...
