TABLE 2 .
Lung lesion scores and HI titers of pigs with preexisting immunity coinfected with SP04 and KS07 viruses and of contact animals
| Group and d.p.i. or d.p.c. |
Mean lung lesion score (%) ± SEMa (no. of pigs with lesions/total no. of pigs) |
Geometric mean HI titer against: |
|
|---|---|---|---|
| KS07 | SP04 | ||
| Vaccinated and coinfected | |||
| 3 | 5.19 ± 3.39 (2/3) | 20 | 10b |
| 5 | 8.19 ± 0.87 (3/3) | 20 | 20 |
| 7 | 4.43 ± 1.05 (3/3) | 20 | 101 |
| Contact | |||
| 4 | 0.86 ± 0.58 (3/3) | 10c | <10 |
| 6 | 0.52 ± 0.25 (3/3) | 10 | <10 |
a
Mean value of the percentage of gross lesions of 7 pulmonary lobes per pig. SEM, standard error of the mean.
b
Only one pig had a detectable titer (1:10).
c
Two pigs had detectable titers (1:10).
