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.
球圆双盘吸虫（吸虫纲）的后尾蚴取自自然感染的弗吉尼亚硬壳螺（肋蜷科）。脱囊后的后尾蚴被分别置于血琼脂平板上。在42℃孵育8小时后，平板出现β溶血现象。反应区直径约为1.5毫米。实验室饲养的绿头鸭（绿头鸭）感染了球圆双盘吸虫。绿头鸭患上了致命的球圆双盘吸虫病，在感染后第3天和第6天凝血酶原时间延长。
