Percentage of pigs with diarrhea and percentage of PEDV RNA positive rectal swabs
| dpi | Percentage of pigs with diarrhea (positive/total number animals, median fecal consistence of pigs with diarrhea) | Percentage of PEDV RNA positive rectal swabs (positive/total number animals, mean log genomic copies per positive rectal swab ± SD) | ||
|---|---|---|---|---|
| 10 day-old pigs | 8 week-old pigs | 10 day-old pigs | 8 week-old pigs | |
| 1 | 4.6%A,1 (2/43, 2) | 0/43A | 18.6%a,2 (8/43, 4.9 ± 1.7) | 18.7a (9/48, 5.4 ± 1.3) |
| 2 | 18.6%A (8/43, 2) | 7.5%A (3/40, 2) | 97.6%a (42/43, 5.7 ± 1.6) | 74.4b (32/43, 6.1 ± 2.1) |
| 3 | 23.2%A (10/43, 3) | 6.6%B (2/30, 2.5) | 100%a (43/43, 7.1 ± 0.8) | 88.3b (38/43, 6.6 ± 1.9) |

1Different uppercase font superscripts (A,B) indicate differences (P = 0.05) in the number of positive animals in the two age groups on a certain dpi.
2Different regular font superscripts (a,b) indicate differences (P < 0.05) in the number of positive animals in the two age groups on a certain dpi. There was no difference between the mean log10 genomic copies per positive rectal swabs between age groups.
