Table 1. Summary of PrPCWD IHC immunoreactivity in lymphoid tissues of subclinical WTD.
| WTD | Tonsil | Retropharyngeal LN | 
|---|---|---|
| 1171 (4 MPI) | 104/129 | 70/112 | 
| 1201 (4 MPI) | 146/183 | 177/232 | 
| 1215 (4 MPI) | 151/191 | 183/216 | 
| 1148 (2 MPI) | 8/134 | 0/95 | 
| 1157 (2 MPI) | 5/125 | 1/99 | 
The number of lymphoid follicle germinal centers with PrPCWD immunoreactivity out of the total number of follicles in the sections examined. This gives a general comparison of how much PrPCWD is present in the tissue by IHC analysis.
