Det är fortfarande gott om dinophysis-alger i vattnet och därför varnar Länsstyrelsens Informationscentral för Västerhavet för att äta musslor

Several Dinophysis species produce diarrhoetic toxins (okadaic acid and dinophysistoxins) and pectenotoxins, and cause gastointestinal illness, Diarrhetic Shellfish Poisoning (DSP), even at low cell densities (<103 cells·L−1). They are the main threat, in terms of days of harvesting bans, to aquaculture in Northern Japan, Chile, and Europe.

View Dinophysis is a genus of dinoflagellates common in tropical, temperate, coastal and oceanic waters. It was first described in 1839 by Christian Gottfried Ehrenberg. Dinophysis - WikiMili, The Free Encyclopedia - WikiMili, The Free Encyclopedia 2018-07-22 Dinophysis species like D. acuta and D. norvegica were never observed to ingest anything at all. This is in agreement with Hallegraeff & Lucas (1988) who examined 5 non-photosynthetic and 3 photosynthetic Dinophysis species by transmission electron micros- copy.

Food selectivity and grazing impact by Acartia bifilosa, Temora longicornis and Centropages typicus on Dinophysis spp. plankton assemblages were experimentally investigated in the Baltic Sea. Toxin analyses were carried out on phyto- and zooplankton-dominated size fractions from field-collected samples to assess if toxins produced by Dinophysis spp.

Synonymer. Information saknas. Delvisa synonymer (pro parte) Dinophysis acuta is a species of flagellated planktons belonging to the genus Dinophysis. It is one of the few unusual photosynthetic protists that acquire plastids from algae by endosymbiosis . By forming massive blooms, particularly in late summer and spring, it causes red tides .

Here, we present morphological analyses, using light and scanning electron microscopy, and rDNA sequence analysis, using a ~2‐kb sequence of ribosomal ITS1, 5.8S, ITS2, and LSU DNA, of Dinophysis Dinophysis sacculus and Alexandrium sp. occurred, in 1993, in shallow inland waters (a brackish lagoon of the Tyrrhenian Sea), characterized by thermo-haline homogeneity. Dinoflagellate species of Dinophysis are obligate mixotrophs that require light, nutrients, and prey for sustained growth. Information about their nitrogenous nutrient preferences and their uptake kinetics are scarce.

They are the main threat, in terms of days of harvesting bans, to aquaculture in Northern Japan, Chile, and Europe.

acuta can be differentiated by its larger size and has its widest section below the mid-section of the cell (below two-thirds of the cell length), while D. norvegica is wide in the middle (Smithsonian 2011). Diarrhetic shellfish poisoning (DSP) is an acute gastrointestinal illness caused by consumption of bivalve mollusks that have accumulated okadaic acid (OA) or related dinophysistoxins through filter feeding. DSP toxins are produced by several species of marine dinoflagellates from the genera Dinophysis and Prorocentrum (1–4).

Dinophysis species are armored dinoflagellates in the family Dinophysiaceae and, like other members of the family, have a consistent non-Kofoidian plate tabulation of 18 to 19 plates: four epithecal plates, two apical plates surrounding an apical pore, four cingular plates, four to five sulcal plates, and four hypothecal plates. This genus is represented by species that have round to ovoid

Diarretisk skaldjursförgiftning uppstår genom olika toxiner som ackumuleras i skaldjur under en period av vissa typer av algblomningar. De alger som dessa toxiner vanligen återfinns i är exempelvis dinoflagellaterna Dinophysis acuminata. Video microscopy from the laboratory of Professor Kimberly Reece at the Virginia Institute of Marine Science shows cells of the alga genus Dinophysis swimming and feeding.

I problemi relativi alla salute non riguardano solo e semplicemente gli antibiotici o i batteri ma anche microscopiche e misteriose alghe come la dinophysis.

Although North American waters have historically been free of Dinophysis blooms and associated DSP poisoning events, Dinophysis species can be a common component of marine phytoplankton.

Dinoflagellate-specific PCR primers were used to isolate small-subunit rRNA (18S rRNA), mitochondrial cytochrome b (cob), and cytochrome c oxidase I (cox1) genes and the encoded cDNAs.
