Table 1 Daily mean (± SD) viremia titers (log pfu/mL serum) for Northern Cardinals (Cardinalis cardinalis) implanted with either corticosterone (n = 10) or an empty silastic tubule (n = 9) and inoculated with a 10 000 pfu of West Nile virus.

  1. Minimum and maximum viral titers are reported for all birds with detectable levels on the given day. dpi = days post-injection. *1.69 log pfu is detection limit of assay.
