Table 1. Summary of pig groups and corresponding numbers, inoculum, and pig diarrhea and death outcomes after inoculation.
| Pig group | Pig numbers | Inoculum dilution* | Calculated inoculum infectious titers (log10 TCID50/mL)† | Diarrhea (percent) | Death (percent) |
|---|---|---|---|---|---|
| Group 1 | 5 | 10−2 | 3 | 5/5 (100) | 5/5 (100) |
| Group 2 | 5 | 10−3 | 2 | 5/5 (100) | 3/5 (60) |
| Group 3 | 5 | 10−4 | 1 | 5/5 (100) | 3/5 (60) |
| Group 4 | 5 | 10−5 | 0 | 3/5 (60) | 1/5 (20) |
| Group 5 | 5 | 10−6 | −1 | 0/5 (0) | 0/5 (0) |
| Group 6 | 5 | Cell culture media | - | 0/5 (0) | 0/5 (0) |
*Each pig was inoculated orally with 1 mL inoculum; †Titers were calculated based on the titer of the original virus pool and dilution times.
