Abstract (EN):
Prevalence values of Trypanosoma granulosum were recorded in European eel, Anguilla anguilla, from 10 Portuguese rivers. 91.8% of the eels captured (n= 743) were infected. The infection prevalence in each sample varied between 50% and 100%. Hemiclepsis marginata and Piscola geometra, the reported vectors for this parasite, were not found. The long period of infection, observed in captive eels held in aquarium, can partially explain the high prevalences. The probability of parasite occurrence is higher in longer hosts.
