Super-Sentinel Chickens and Detection of Low-Pathogenicity Influenza Virus
|Day postinfection||Water (IPE/mL)||Water + interferon† (IPE/mL)|
|2||1,112 ± 1,353‡||760 ± 632|
|4||1,234 ± 764||463 ± 484|
|10||1,325 ± 398||2,113 ± 1,834|
*Each cage contained 2 overtly infected birds and 8 cage mates as sentinels. Only sentinel birds are reported. Chickens were 3 weeks old at the start.
†Recombinant chicken interferon-α in water at 2,000 U/mL (5).
‡Mean ± SD, n = 8. Qualitative real-time reverse transcriptase–PCR analysis with influenza A virus standard: IPE/mL.
