Evaluation of porcine epidemic diarrhea virus transmission and the immune response in growing pigs

Table 2 Fecal swab PCR results for Stationary Group, Principal Group, Sentinels, and Naïve/Challenged group From Day 47–77**

*On Day 0, the seeder pig (SG-1) was orally challenged with PEDV. On Days 1 and 2, 1 and 12 contact pigs, respectively were placed with the seeder pig. On Day 7, the Principal Group (PG) consisting of 9 contact pigs, and the Stationary Group (SG) consisting of 4 contact pigs and the seeder pig were selected. On Days 7, 14, 21, and 28, Sentinel pigs S1, S2, S3, and S4, were commingled with the PG, respectively. On Days 10, 17, 24, and 31, the respective sentinel pig was removed and placed in a separate room. S1 was euthanized and necropsied on Day 30. All other study animals were euthanized and necropsied on Day 78. Samples not collected D36-39. **PG and N/C pigs were orally challenged with CO-13 PEDV on D49. Cycle Threshold of ≤ 35 = positive result (+); Cycle Threshold of ≥ 36 = negative result (−), empty box = sample not collected.
