Bacterial diversity of Gymnodinium catenatum and its relationship to dinoflagellate toxicity [PDF]

Aquatic Microbial Ecology, 2010
Gymnodinium catenatum Graham (Dinophyceae) is one of several marine dinoflagel- lates responsible for outbreaks of paralytic shellfish poisoning (PSP), a problem that is considered to be increasing globally. Bacteria associated with these dinoflagellates have been implicated as poten- tially involved with the production of PSP toxins, and this study ...

Cyst and radionucleotide evidence for the recent introduction of the toxic dinoflagellate Gymnodinium catenatum into Tasmanian waters

Marine Ecology - Progress Series, 1997
Cysts of the dinoflagellate Gymnodinium catenatum were present only in the top sections of duplicate marine sediment cores from Deep Bay in southern Tasmania, Australia.

Toxin production of dinoflagellate Gymnodinium catenatum isolated from the East China Sea

Harmful Algae, 2022
Dinoflagellate Gymnodinium catenatum is an important producer of paralytic shellfish toxins (PSTs), including a novel group of hydroxybenzoate derivatives named GC toxins. In the East China Sea, G. catenatum has been considered as the causative agent for several paralytic shellfish poisoning (PSP) episodes, yet the knowledge on their toxin production ...

THE UNIQUE, MICRORETICULATE CYST OF THE NAKED DINOFLAGELLATE GYMNODINIUM CATENATUM

Journal of Phycology, 1988
Gymnodinium catenatum Graham is an unarmored dinoflagellate responsible for episodes of paralytic shellfish poisoning. This species forms a resting cyst that is unique in several ways. The outer surface of the spherical, brownish cyst is microreticulate and composed of hundreds of 1-3 μm polygons.

Metabolites of saxitoxin analogues in bivalves contaminated by Gymnodinium catenatum

Toxicon, 2010
Bivalve metabolites of saxitoxin analogues, not present in microalgae, were recently described as an important toxin fraction in mussels contaminated by Alexandrium tamarense. These possess very low fluorescence, and require mass spectrometry detection.

Dinoflagellate Gymnodinium catenatum as the source of paralytic shellfish toxins in Tasmanian shellfish

Toxicon, 1987
Paralytic shellfish toxins in both cultured cells and natural phytoplankton blooms of the dinoflagellate Gymnodinium catenatum from inshore Tasmanian waters (Australia) were analyzed by high performance liquid chromatography, thin layer chromatography and electrophoresis techniques. The dinoflagellate toxins were dominated by low potency sulfocarbamoyl

Paralytic shellfish poisoning in northwest Spain: The toxicity of the dinoflagellate Gymnodinium catenatum

Toxicon, 1989
The highly productive mussel fishery in the Rias Bajas region of northwest Spain has experienced several outbreaks of paralytic shellfish poisoning (PSP) beginning in 1976. In this study, similarities in the HPLC analyses of extracts from toxic shellfish, plankton tows and cultured dinoflagellates from the Rias Vigo and Pontevedra clearly indicate that

Grazing impacts of the heterotrophic dinoflagellate Polykrikos kofoidii on a bloom of Gymnodinium catenatum [PDF]

Aquatic Microbial Ecology, 1999
In 1998, a red tide of the paralytic shellfish poisoning (PSP)-producing dinoflagellate Gymnodinium catenaturn Graham occurred in Yatsushiro Sea, western Japan. The dramatic decline of dominant G. catenatum cells occurred during the field and laboratory assessments, accompanied with growth of the heterotrophic dinoflagellate Polyknkos kofoidii Chatton.

Ultrastructure of the toxic, chain-forming dinoflagellate Gymnodinium catenatum (Dinophyceae)

Phycologia, 1991
Abstract The ultrastructure of the toxic, chain-forming dinoflagellate Gymnodinium catenatum Graham (Dinophyceae)is described from wild and cultured cells from estuaries in south-east Tasmania, Australia. The cell covering (amphiesma) comprises numerous (> 1500) small polygonal vesicles, which lack plate-like contents, and are arranged in irregular ...
