Observations sur le developpement deClestobothrium crassiceps(Rud., 1819) (Cestoda, Pseudophyllidea) parasite intestinal deMerluccius merlucciusL. , 1758 (Teleostei)

Ligula intestinalis (Cestoda: Pseudophyllidea): an ideal fish-metazoan parasite model?

Since its use as a model to study metazoan parasite culture and in vitro development, the plerocercoid of the tapeworm, Ligula intestinalis, has served as a useful scientific tool to study a range of biological factors, particularly within its fish intermediate host. From the extensive long-term ecological studies on the interactions between the parasite and cyprinid hosts, to the recent advanc...

Experimental infection of Atlantic salmon (Salmo salar) with marine Eubothrium sp. (Cestoda: Pseudophyllidea): observations on the life cycle, aspects of development and growth of the parasite.

The life cycle of marine Eubothrium sp. (Cestoda: Pseudophyllidea), from Atlantic salmon (Salmo salar L.) was experimentally completed in one year and included only one intermediate host (Acartia tonsa Dana) (Copepoda: Calanoida). Adult cestodes were collected from farmed salmon, and ripe eggs released by the cestodes were fed to Acartia tonsa. Ingested eggs hatched in the gut and the larvae de...

Sur le groupe d’interpolation

Résumé : Nous étudions le groupe d’interpolation dont les éléments sont certaines paires de séries formelles. Ce groupe possède une représentation linéaire fidèle dans les matrices triangulaires inférieures infinies. On peut donc le munir d’une structure de groupe de Lie naturelle. Une fonction reliée à l’exponentielle matricielle entre son algèbre de Lie et sa représentation linéaire étend alo...
