Gram-negative rodsShortening the turnaround time of antimicrobial susceptibility testing (AST) of bacteria permits a significant reduction of patient morbidity, mortality, and cost. Conventional blood culture methods are the gold standard diagnostic test to guide management of patient with sepsis, but ...
Despite the error rate, the advantages of earlier times to effective and targeted antibiotics justifies continuing direct testing in bacteraemia episodes with Gram-negative rods. In the Gram-positive group, given the contamination rate, the availability of adjunctive PCR, and the fact that early ...
Sensitivity/specificity was 98.4/75.0% for Gram-positive cocci in chains/pairs; 93.2/97.2% for Gram-positive cocci in clusters; and 96.3/98.1% for Gram-negative rods. Taken together, our data support proof-of-concept for a fully automated classification methodology for blood-culture Gram-stains....
We evaluated the new GenotypeBC Gram-negative and Gram-positive test kits (Hain Life Science, Germany) which respectively allow for the identification of 15 species of Gram-negative (GN) rods, and the identification of 17 Gram-positive (GP) bacteria species together with the determination of ...
Effects of anti-neoplastic agents on the recovery of bacteria and yeasts in an automated blood culture system. The effects of 7 anti-neoplastic agents on the recovery of 5 aerobic gram-positive cocci, gram-negative rods and yeasts were studied in 2 different automat... U Kinnunen,P Koistinen...
Evaluation of the new GNR Traffic Light PNA FISH® fluorescence in situ hybridisation probes for rapid same-day identification of Gram-negative rods ... L Leerbeck,D.S. Hansen (Hillerød,DK) 被引量: 0发表: 0年 In vivo and in situ visualization of early physiological events induced ...
Consecutive bone marrow and peripheral blood progenitor cell preparations (n = 893) were cultured; the overall positive rate detected was 2.5 percent (22/893). The isolates predominantly were skin contaminants (gram-positive cocci) and so-called water-borne organisms (gram-negative rods). The 6.0...
The rapid ATP bioluminescence-based method consists of four steps (Fig.1). First, to exclude blood corpuscles, a positive blood culture specimen in a serum separator tube is centrifuged, causing the erythrocytes and leukocytes to move under the separation gel of the tube. To obtain a bacterial...
The results also indicated some loss of viability. The impact was greatest on Gram negative rods. Example 3 Detection ofStaphylococcus aureusfrom Selective Lysis of Whole Blood Versus Routine Blood Culture Staphylococcus aureus(SA) that had been diluted serially was inoculated into sterile, fresh, who...
Attempts to culture the causative organism have been unsuccessful, but microscopical examination of infected tissue, usually small-bowel-biopsy specimens or lymph nodes, reveals small gram-positive rods that appear as diastase-resistant intracytoplasmic inclusions on periodic acid-Schiff staining2. Electron...
