Abstract

Copepod hosts for freshwater North American species of Diphyllobothrium are presently unknown. First intermediate hosts previously reported were based on the assumption that European host species are also hosts in North America. Our primary objective was to identify North American calanoids that could be used in the laboratory to transmit Diphyllobothrium dendriticum to fish and could also act as hosts for the parasite in natural lakes. A secondobjective was to establish an infection protocol that arrowed high rates of prevalence and mean intensity of infection to be obtained with the use ofthese copepods and Arctic charr Salvelinus alpinus. Our experiments indicated that Diaptomus (Aglaodiaptomus) leptopus and Diaptomus (Leptodiaptomus)minutus readily became infected by coracidia of D. dendriticum (prevalence14.9-60.8%), it is likely that D. (L.) minutus is a natural host for D. dendriticum because it co-occurs in lakes with infected Arctic charr. Both copepods successfully transmitted D. dendriticum to Arctic charr (prevalenceswere 72.3% and 52.6%). The rate of parasite establishment was lower (7.7%)in fish given 10-20 procercoids than it was for a dose range of 6- 12 procercoids (29.3%). These data suggest that if infection intensity greater than 10 plerocercoids is desired, it may be more effective to repeatedly expose fish to fewer parasites rather than use a single higher dose.
