Table II.
Number of viral RNA copies in BHK-LV cells post-infection with FMDV at different time points.
| Cell line | 12 h | 18 h | 24 h | 36 h | 48 h |
|---|---|---|---|---|---|
| BHK-21 | 1.33×108a | 7.09×107 | 6.82×107a | 6.00×107 | 6.62×107 |
| (±2.38×106) | (±1.22×107) | (±2.41×107) | (±6.82×106) | (±9.29×106) | |
| BHK-21-LV | 8.10×107 | 4.32×107 | 2.22×107 | 3.28×107 | 4.53×107 |
| (±2.00×107) | (±3.86×106) | (±4.99×106) | (±2.86×106) | (±1.26×107) |
The numbers in parentheses represent the standard error of the mean calculated from at least three independent experiments.
a
Significant differences between numbers of viral RNA copies in BHK-21 and BHK-21-LV cells at 12 and 24 h were analyzed by one-sample t-test (P<0.05). FMDV, foot-and-mouth disease; LV, lentivirus.
