| Group | No. of pigs | Mortality rate, % (no./total) | Severe diarrhea rate, % (no./total)a | Duration of severe diarrhea (days)a | Duration of diarrhea (days)a | Peak mean RNA shedding titer (log10 N gene copies/mL) |
|---|---|---|---|---|---|---|
| N93/95A | 3 | 0 (0/3) | 0 (0/3) Ab | 0.00 ± 0.00 A | 3.67 ± 0.58 A | 5.57 ± 0.89 A |
| Mock inoculated | 4 | 25% (1/4) | 100 (4/4) B | 6.00 ± 0.82 B | 7.25 ± 1.50 B | 9.98 ± 0.93 B |
a
Fecal scores of 2 and 3 were considered moderate diarrhea and severe diarrhea, respectively.
b
Different letters denote significant difference between groups (P < 0.05).
