TABLE 1.

Prevalence of antibodies to avian influenza in 3,205 Canada geese (Branta canadensis) from nine US states as determined by blocking enzyme-linked immunosorbent assay and prevalence of viral RNA detection for 685 Canada geese with the use of a matrix real-time reverse-transcriptase polymerase chain reaction (rRT-PCR).
