FIG. 1.

Differences in lengths of time to detection of contaminants in platelet units for the BACTEC culture system versus the BacT/Alert culture system. The data points for eight isolates with detection time differences of greater than 5 h were not included in this figure: one coagulase-negative Staphylococcus sp. (CONS) (−8.9 h) and seven viridans group streptococci (+12.4, −6.4, −11.8, −12.6, −13.0, −15.7, and −19.0 h). The “Others” category includes eight Serratia spp., one Micrococcus sp., four aerobic diphtheroids, and two Enterobacter spp.
