Table 2B The weight of each investigated tissue sample of all subjects and in case of PJI its effect on the rate of positive culture results using Disperser vs. Bead milling method
Proportion of investigated samples based on weight | ||||
|---|---|---|---|---|
PJI1 Culture positive (n = 34) | > 1.5 g | 0.5-1.5 g | < 0.5 g | All sizes |
Disperser (no. of positive cultures/ total no. of specimens [%]) | 71/87 (82) | 41/53 (77) | 8/13 (62) | 120/153 (78) |
Bead milling (no. of positive cultures/ total no. of specimens [%]) | 72/90 (80) | 37/48 (77) | 12/17 (71) | 121/155 (78) |
PJI1 Culture negative (n = 6) | ||||
Disperser (no. [%]) | 18 (64) | 7 (25) | 3 (11) | 27 |
Bead milling (no. [%]) | 15 (56) | 7 (26) | 5 (18) | 27 |
AF2 (n = 40) | ||||
Disperser (no. [%]) | 89 (49) | 66 (37) | 25 (14) | 180 |
Bead milling (no. [%]) | 90 (50) | 64 (36) | 26 (14) | 180 |
