Experimental infections of waterfowl with Sphaeridiotrema globulus (Digenea)

Experimental infections of waterfowl with Sphaeridiotrema globulus (Digenea)

Journal of Wildlife Diseases 25(1): 143-146

S. globulus in experimentally infected mute swans (Cygnus olor), mallard ducks (Anas platyrhynchos) and Canada geese (Branta canadensis) induced ulcerative haemorrhagic enteritis. Sites of infection included the jejunum and ileum. The digeneans caused ulceration of the intestine. The inflammatory response was primarily lymphocytic with some eosinophils. Severe haemorrhage from damaged submucosal capillaries provided a blood meal for the parasite and caused anaemia in the host. Extra-medullary haemopoiesis occurred in the liver, and an erythroid hyperplasia occurred in the bone marrow of infected birds. Infected birds exhibited muscular weakness and died from shock associated with severe blood loss. Mallards and Canada geese were less susceptible to fatal infection than the mute swan as evidenced by survivors in the higher dose groups.
