| Serum sample no. | Mean bacterial count in log CFU/ml (standard error) for straina

|||
|---|---|---|---|---|
| C5 | C5M2 | C5M4 | ECOR 4 | |
| 1 | 6.7 (0.7) | 5.7 (0.8)b | 5.8 (0.9)b | 2.8 (0.9)c |
| 2 | 5.7 (1.1) | 5.8 (0.6)b | 5.37 (0.8)b | 2.3 (0.6)c |
| 3 | 5.3 (0.8) | 4.91 (0.4)b | 4.95 (0.5)b | 2.5 (0.8)c |
a
Bacterial count was obtained 5 h after exposure to a 107 CFU per ml standardized inoculum in serum.
b
P, nonsignificant versus C5 bacterial count.
c
P< 0.05 versus C5 bacterial count.
