Comparison of the IgG antibody titers of NcSUB1t, NcSUB1tr, N54, and NcSAG1t against serially diluted sera from experimentally infected cattle
| Antigen | Antibody titera |
|||
|---|---|---|---|---|
| Calf 1 | Calf 2 | Calf 3 | Calf 4 | |
| NcSUB1t | 1:4,000 | 1:8,000 | 1:1,000 | 1:1,000 |
| NcSUB1tr | 1:1,000 | 1:1,000 | 1:1,000 | 1:2,000 |
| N54 | 1:1,000 | 1:250 | 1:250 | BC |
| NcSAG1t | 1:1,000 | 1:1,000 | 1:1,000 | 1:500 |

Serum samples used were at 16 days postinfection. The values shown represent the highest serum serial dilution by which specific antibodies against N. caninum were detected. The cutoff values are 0.085 for anti-NcSUB1t IgG and 0.040 for anti-NcSUB1tr. BC, below cutoff.
