Cynomolgus macaques infected with CWD agent*
| No. monkeys | CWD inoculum | Route of inoculation | Titer inoculated† | Current mpi |
|---|---|---|---|---|
| 1 (no. 609)‡ | MD-1 | Intracerebral | 2.5 × 106 | NA |
| 1 | MD-1 | Intracerebral | 2.5 × 106 | 70 |
| 3 | MD-1 | Oral | 2.0 × 109 | 70 |
| 2 | Elk-1 | Intracerebral | 3.2 × 105 | 70 |
| 3 | Elk-1 | Oral | 2.5 × 108 | 70 |
| 2 | WTD-1 | Intracerebral | 1.0 × 106 | 70 |
| 3 | WTD-1 | Oral | 1.2 × 109 | 70 |
*CWD, chronic wasting disease; mpi, months postinfection; NA, not available.
†Infectivity titers were determined by using endpoint dilution titer in transgenic deer expressing mouse prion protein and are listed as the total 50% infectious dose/g of brain.
‡Monkey 609 was euthanized at 48 mpi, and no protease-resistant prion protein was detected by Western blot or immunohistochemical analysis.
