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.
