An Epizootic among Knots (Calidris canutus) in Florida I. Disease Syndrome, Histology and Transmission Studies
About 150 knots found sick or dead had distention of serosal blood vessels, and small, raised hemorrhagic foci on the serosal surface of the jejunum and ileum. The principal finding was endaortitis with large intimal multinucleated cysts that contained a protozoan parasite within a cytoplasmic vacuo...
