^aCynomolgus macaques were infected with 6.7 × 10⁷ PFU through multiple routes. Nasal wash and tracheal brush samples were collected every other day for virus titration.

^b—, virus not detected (detection limit, 1.3 log₁₀ PFU/ml.

^cThese animals were euthanized on day 7 postinfection for virologic and pathological analyses.

^dThis animal died during the bronchoalveolar lavage procedure on day 3 postinfection.

^eThese animals had Plasmodium spp. in their erythrocytes; however, their erythrocyte counts were normal.

^fNA, not applicable.

^gBAL, bronchoalveolar lavage.
