| Serum | Inhibitory dosage | MI antibody titer with indicated complement source |
|
|---|---|---|---|
| GPS | RS | ||
| Rabbit negative serum | <10 | <8 | <8 |
| Rabbit anti-M. bovis serum | 106 | 256 | 512 |
| Rabbit anti-PDHE2 serum | <10 | <8 | <8 |
| Rabbit anti-PNP serum | <10 | <8 | <8 |

a
Inhibitory dosage, the concentration of the maximum dilution of M. bovis for which the medium remained red, was determined as the maximum mycoplasmacidal dosage with antiserum at a 1:20 dilution. MI titer is the concentration of the maximum antibody diluted at which the medium remained red.
