*Shedding was determined by real-time reverse transcription–PCR of nasal swabs compared with standard curves generated from avian influenza virus stocks of known concentrations and expressed as log₁₀ 50% egg infectious dose equivalents. –, no viral RNA detected. Raccoons 262 and 263 were seropositive for avian influenza virus before inoculation.
†Uninoculated raccoons housed in cages adjacent to infected raccoons.
‡Raccoon humanely killed 8 days postinoculation.
