In all cases, mice were trained to select the maze arm associated with the odor of feces collected after experimental AIV infection. “Pre” indicates feces collected prior to experimental infection; “Post” indicates collection after infection. Ducks 5 and 12 were experimentally infected with avian influenza. Ducks 1 and 2 received a sham treatment. Responses were subjected to tests of binomial proportions equal to 50%.

¹Indicates rate of selection of 12 - Pre sample.

²Indicates rate of selection of 5 - Post sample.
