Hepatogenous photosensitisation in Scottish sheep casued by Dicrocoelium dendriticum

摘要: Dicrocoeliosis was identified as the probable predisposing cause of weight loss and hepatogenous photosensitisation affecting half a group 14 month-old ewe lambs on farm Inner Hebridean island Coll. Oral dosing with 15 mg/kg albendazole only achieved 79.2% reduction in Dicrocoelium dendriticum egg count, 21 day post treatment. Thus, this report dicrocoeliosis differs from disease that occurs elsewhere, both severity nature its clinical signs, response parasite to anthelmintic drug These differences could indicate existence genetically divergent D. population, which may have evolved within unique isolated biotope afforded by machair Better understanding these factors is prerequisite for effective sustainable control.
