چکیده

The one-bottle Oxoid Signal blood culture system altered to provide a more aerobic bottle headspace was reassessed in a comparative study versus the two-bottle BACTEC radiometric system in 5,426 blood cultures. The BACTEC system detected more microorganisms (P less than 0.02), particularly anaerobes (P less than 0.05) and fungi (P less than 0.05).

Effect of agitation and terminal subcultures on yield and speed of detection of the Oxoid Signal blood culture system versus the BACTEC radiometric system.

In an initial evaluation, we found the Oxoid Signal blood culture system inferior to the BACTEC radiometric system for detection of some microorganisms causing septicemia (M. P. Weinstein, S. Mirrett, and L. B. Reller, J. Clin. Microbiol. 26:962-964, 1988). To determine whether modified processing of the Oxoid Signal blood culture system could improve its yield and speed of detecting positive c...

Comparative evaluation of nonradiometric BACTEC and improved oxoid signal blood culture systems in a clinical laboratory.

The BACTEC NR660 blood culture system, which uses infrared spectroscopy to detect carbon dioxide generated by bacterial growth, was compared with the new medium formulation of the Oxoid Signal system. Two trials were conducted: a comparative study of 88 organisms in simulated blood cultures and a clinical trial of 3,321 paired patient blood culture samples. Both trials showed that overall the B...

تشخیص بروسلوز با استفاده از سیستم کشت خون ‌ BACTECو تائید نتایج آن با PCR

Abstract: Brucellosis is one of the most common zoonotic diseases in Iran. Growth of Brucella is slow and blood cultures of these bacteria are time-consuming via classical methods. We try to evaluate BACTEC 9120 system capacity in order to detect of bacteremia due to Brucella spp and to confirm isolated bacteria by PCR. Blood culture sample of 102 suspected patients evaluated by BACTEC 9120 sys...

Comparison of radiometric and gas capture systems for blood cultures.

A single bottle blood culture system that detects the gas produced by micro-organisms from substrates in a specially formulated medium was compared with the Bactec radiometric system. A total of 725 blood samples collected from patients with suspected bacteraemia yielded 75 clinically important isolates. Fifty five (73%) of these cultures were detected by both methods, 16 (21%) by only the Bact...

Controlled evaluation of supplemented peptone and Bactec blood culture broths for the detection of bacteremia and fungemia.

Comparison of conventional blood culture media with newer formulations of Bactec media for radiometric detection are lacking. Therefore, we compared the yield and speed of detection of clinically important microorganisms with supplemented peptone broth (SPB) and Bactec aerobic (6B) and anaerobic (7C or 7D) broths in 7,627 blood samples from adult patients. Acridine orange stains from SPB, radio...
