title: The transport of albendazole and albendazole sulphoxide in the lancet fluke (Dicrocoelium dendriticum).
abstract: Albendazole (ABZ) is one of the most important benzimidazole compounds possessing high activity against the lancet fluke, Dicrocoelium dendriticum. ABZ sulphoxide (ABZ.SO) is the main molecule present in the bloodstream of an ABZ-treated host. The aim of this study was to characterise the pattern of ex vivo uptake of ABZ and ABZ.SO by lancet flukes and the export of both anthelmintics from these parasites. Transport of these anthelmintics in both living and dead flukes was compared. The adult flukes were collected from mouflons (Ovis musimon) which had been infected naturally. Results showed that more lipophilic ABZ was imported to a higher extent than ABZ.SO, and that significantly higher concentrations of ABZ were detected within living flukes as compared to dead ones. The same pattern was revealed in the study of ABZ and ABZ.SO export from the flukes' bodies. In addition to passive diffusion, active ABZ uptake and active efflux of ABZ and ABZ.SO in D. dendriticum could be assumed.
