Stability of serum antibodies in ruddy turnstones after inoculation with low-pathogenic avian influenza virus A/shorebird/DE/42/2006 (H7N3). Birds were maintained for the number of days postinoculation (DPI) indicated, and sample/negative control (S/N) ratios were determined in 4 birds by using IDEXX MultiSpecies ELISA. S/N ratios <0.50 are considered seropositive.
