An Epizootic among Knots (Calidris canutus) in Florida II. Ultrastructure of the Causative Agent, A Besnoitia-like Organism
Multinucleated cysts near the luminal surface of the thoracic aortas of diseased knots (Calidris canutus) were similar to besnoitia cysts. Ultrastructurally, the cyst had four distinct layers. The central area included a vacuole that contained a sporozoan with a conoid, polar ring, micronemes, rhopt...
