---|---|---|---|
Type of inoculated microorganism | Reference: 18–48 h subculture + Vitek®MS identification | Direct identification from positive blood culture using BCSP prototype with BacT/ALERT 3D, SA bottles, and Vitek®MS identification | Direct identification from positive blood culture using BCSP prototype with BacT/ALERT Virtuo, FA Plus bottles, and Vitek®MS identification |
Gram-negative species | 96 % [91–99]% | 85% [79–89]% | 86% [71–95]% |
Gram-positive species | 98 % [93–100]% | 88% [82–92]% | 86% [71–95]% |
Yeast species | 100 % [81–100%] | 100% [90–100]% | 75% [48–93]% |
Overall ID rate | 97.3% [94–99]% | 87% [84–90]% | 84% [75–91]% |
SA and FA Plus bottles were inoculated with microorganisms belonging to strain collection of the study and were incubated in BacT/ALERT 3D® and BacT/ALERT Virtuo® systems, respectively. Results were compared with reference method based subculture of positive blood culture bottle (COS plate) and identification by Vitek®MS system. The results in square brackets are the 95% two-sided exact confidence interval.
