TABLE 1.
Number of pits in TGEV-infected and uninfected pAPN-MDCK and TLpAPN-MDCK cellsa
| Cell type | No. of pits per cell profile (SE) | No. of profiles |
|---|---|---|
| pAPN-MDCK | ||
| TGEV infected | 1.83 (0.16) | 80 |
| Uninfected | 0.43 (0.08) | 68 |
| TLpAPN-MDCK | ||
| TGEV infected | 0.73 (0.11) | 136 |
| Uninfected | 0.46 (0.08) | 70 |
The number of pits on each cell profile seen in the electron microscope at 10 min (pAPN-MDCK cells) or 30 min (TLpAPN-MDCK cells) postadsorption was counted.
