Echiurophilus fizei n. g. n. sp. Copépode parasite d'un echiuride d'Indochine

This paper deals with the description of Echiurophilus fizei. The worm has been recorded from the digestive tract of Thalassema inansense Ikeda in Vietnam in 1955.

Transmission electron microscopy of marine crustacean eggs

Ultrastructural investigations of eggs can be important in helping to understand embryonic development. There are few transmission electron microscope studies of marine arthropod eggs, however, as they have proved difficult to fix and infiltrate with resin. Here, we describe a modification of a standard method that allows the preparation of the quite different eggs of the marine copepod, Acartia tonsa and the lobster, Homarus gammarus, for transmission electron microscopy. By using double fixation and an extended resin infiltration time we obtained good preparations for electron microscopy. We anticipate that these modifications to the standard protocol will be widely applicable and useful for the study of the eggs and early developmental stages of many marine arthropod taxa. Les recherches sur l'ultrastructure des oeufs peuvent être importantes en aidant à comprendre le développement embryonnaire. Il existe cependant peu d'études en microscopie électronique à transmission sur les oeufs d'arthropodes marins, car il est difficile de les fixer et d'y infiltrer de la résine. Dans ce travail, nous décrivons une modification de la méthode standard, qui permet la préparation pour la microscopie électronique à transmission d'oeufs aussi différents que ceux du copépode marin Acartia tonsa et du homard Homarus gammarus. En utilisant une double fixation et un temps plus long d'infiltration de la résine, nous avons obtenu de bonnes préparations pour la microscopie électronique. Nous prévoyons que ces modifications du protocole standard seront largement applicables et utiles pour l'étude des oeufs et des premiers stades de développement de nombreux taxons d'arthropodes marins.
