TABLE 3.
Monitoring strain | Uptake rate (CFU h−1 specimen−1)b | No. of bacteria in the gut (CFU specimen−1)c | No. of bacteria in feces (CFU fecal pellet−1)d | Release rate (no. of fecal pellets specimen−1 h−1) | Reduction factore |
---|---|---|---|---|---|
Escherichia coli S17-1 pRP4-luc | 5.13 × 105 | 4.29 × 100 | 1.72 × 100 | 485 | 61,588 |
Sinorhizobium meliloti L33 | 7.49 × 106 | 2.34 × 104 | 8.79 × 101 | 224 | 38,077 |
Alcaligenes faecalis HR4 pRP4-luc | 6.90 × 105 | 3.00 × 104 | 5.71 × 102 | 248 | 487 |
All data shown for each parameter were significantly different from each other (P ≤ 0.05).
Determined with three parallel incubations.
Determined with 10 specimens per species.
Determined with four parallel incubations.
The reduction factor is the uptake rate per number of cells of the monitoring strain in the feces per release rate.
