title: Hemolytic and coagulation properties of Sphaeridiotrema globulus (Trematoda).
abstract: Metacercariae of Sphaeridiotrema globulus (Trematoda) were obtained from naturally infected Goniobasis virginica (Pleuroceridae). Excysted metacercariae were placed individually on blood-agar plates. After 8 hr of incubation at 42 C the plates exhibited beta-hemolysis. The reaction zone was approximately 1.5 mm in diameter. Laboratory-reared mallard ducks (Anas platyrhynchos) were infected with S. globulus. Mallards developed fatal sphaeridiotremiasis and demonstrated increased prothrombin time on days 3 and 6 postinfection.
