A mortality in muscovy ducklings caused by infection with the intestinal fluke, S. globulus, is described. The disease was characterised by depression, anorexia, wasting, diarrhoea and high mortality. The major pathological lesions were associated with the attachment sites of the flukes and consisted of severe enteritis with ulceration, principally affecting the jejunum, but also involving the duodenum and ileum. Experimental infections were produced in ducklings by oral administration of either G. austrialis infected with S. globulus metacercariae or S. globulus metacercariae or S. globulus metacercariae. The small, dextral, operculate snail G. australis was identified as the intermediate host and G. australis and an unidentified planorbid as transport hosts. L. tomentosa was also able to be a transport host. The epidemiology of the outbreak and aspects of acquired resistance are presented.
描述了由感染肠道吸虫球形斯克里亚宾吸虫（S. globulus）导致番鸭雏鸭死亡的情况。该病的特征为精神沉郁、厌食、消瘦、腹泻和高死亡率。主要病理损伤与吸虫的附着部位有关，表现为严重的肠炎并伴有溃疡，主要影响空肠，但也累及十二指肠和回肠。通过口服感染了球形斯克里亚宾吸虫后尾蚴的澳大利亚扁卷螺（G. austrialis）、球形斯克里亚宾吸虫后尾蚴或球形斯克里亚宾吸虫后尾蚴，在雏鸭中引发了实验性感染。小型右旋有盖螺澳大利亚扁卷螺被确定为中间宿主，澳大利亚扁卷螺和一种未鉴定的扁卷螺为转运宿主。绒毛扁卷螺（L. tomentosa）也能够成为转运宿主。介绍了此次疫情的流行病学情况以及获得性抗性的相关方面。
