A new species of the genus Aeolosoma (Annelida: Aphanoneura: Aeolosomatidae) with peculiar sigmoid chaetae from fresh waters of Vietnam.

A new species of the Aeolosomatidae, Aeolosoma vietnamicum sp. n., found in freshwater bodies of Vietnam, is illustrated and described.

The ultrastructure of the zoospores of the parasitic dinoflagellate Ichthyodinium chabelardi Hollande et J. Cachon, 1952 (Alveolata: Dinoflagellata).

This is the first study on the ultrastructure of the zoospores of Ichthyodinium chabelardi, a parasitoid of the fish egg and early larval stages. The zoospores were characterized by the cell structure specific for dinoflagellates; particularly, cells contained large trichocysts and the "dinokaryon"-type nucleus. An unusual large electron-transparent zone was the only significant difference from the "classical" cell structure in Dinoflagellata.

Screening of marine bacteria with bacteriocin-like activities and probiotic potential for ornate spiny lobster (Panulirus ornatus) juveniles.

Bacteriocins are ribosomally synthesized antimicrobial peptides, which have been found in diverse bacterial species of terrestrial origins and some from the sea. New bacteriocins with new characteristics, new origins and new applications are likely still awaiting discovery. The present study screened bacteria isolated from marine animals of interest to the aquaculture industry for antimicrobial and bacteriocin-like activities in order to uncover biodiversity of bacteriocin producers, and explore the potential application in aquaculture.
