Bacterial activity responses of rabbit sera to homologous and heterologous E. coli strains
| Serotype | No. of CFU (105) for rabbit serum immune toa:
|
|||
|---|---|---|---|---|
| Preimmune | O7 | O116 | O157 | |
| O7:NM | 75.0 | 9.0 | 8.4 | 3.8 |
| O116:NM | 67.5 | 8.7 | 59.5 | 5.5 |
| O157:H7 | 70.5 | 6.2 | 8.7 | 8.7 |
| O157:H19 | 70.5 | 12.7 | 46.6 | 7.7 |
The values are for the last serum dilution showing bacterial activity with a statistically significant difference (P < 0.05) when the results obtained were compared with those observed with preimmune serum.
