[Experimental approach to the role of the paratenic host in the circulation of the parasite Bothriocephalus claviceps Goeze, 1782 (Cestoda, Pseudophyllidea)].
This article concerns an experimental work monitored in 5 species of fishes in the order to evaluate their value of paratenic hosts, in the cycle of Bothriocephalus claviceps, a parasite of the eel, Anguilla anguilla. The intestinal localisation and the lack of development of parasites are the two principal characters of this parasitism. The second character is sometimes contradicted. The effective evolution has been observed during 20 days. The more important losses of parasites coincide with the invasion of fishes. After that stage, the decrease of effectives is slower. The authors are led to consider that two modes of circulation are required for the parasite: the direct transmission and the transmission with intercalation of paratenic hosts.
