  • a Values represent mean PIs ± standard deviations. Sera taken at 7 and 14 dpi had neutralizing antibody levels based on PRNT90 values of ≥100 for WNV, while neutralizing antibodies were undetectable in mock-infected sera by PRNT. At 0, 7, and 14 dpi, 5, 4, and 3 animals, respectively, were sacrificed for testing.

  • b ND, not done.
