TABLE 1.
Bacterial loads of positive BCs over 8 h and recovery rate by SST procedure (phase I)
| Incubation conditions and specimen source | Bacterial load or recovery rate at the following times after first bottle turned positivea:
|
|||
|---|---|---|---|---|
| 0 h | 2 h | 4 h | 8 h | |
| Aerobic (n = 5) | ||||
| BACTEC bottle | 15.6 ± 4.8 | 17.6 ± 4.3 | 17.0 ± 2.9 | 17.2 ± 7.5 |
| ID broth | 12.0 ± 4.3 | 12.8 ± 3.5 | 10.8 ± 3.3 | 12.4 ± 3.3 |
| Anaerobic (n = 5) | ||||
| BACTEC bottle | 14.6 ± 6.1 | 15.5 ± 6.1 | 13.1 ± 6.2 | 14.4 ± 4.8 |
| ID broth | 6.7 ± 3.0 | 6.6 ± 3.6 | 7.1 ± 3.6 | 8.0 ± 3.5 |
a
Bacterial loads are numbers of E. coli ATCC 25922 CFU (108) per milliliter for BACTEC bottles, and recovery rates are numbers of bacteria in ID broth. Values are means ± standard deviations.
