A new dinoflagellate species, Azadinium poporum sp. nov., was isolated as three clones from the southern North Sea off the Danish coast. In contrast to the type species A. spinosum, a known producer of azaspiracid (AZA) toxins, the isolates of A. poporum produce no known AZA analogues detectable by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Azadinium poporum is a small (11–16 µm length; 8–12 µm width) photosynthetic dinoflagellate with a thin theca exhibiting the… 

A new potentially toxic Azadinium species (Dinophyceae) from the Mediterranean Sea, A. dexteroporum sp. nov.

LC/MS‐TOF analysis shows that Azadinium dex‐teroporum produces azaspiracids in low amounts and some of them have the same molecular weight as known compounds such as azAspiracid‐3 and ‐7 and Compound 3 from Amphidoma languida, as well as similar fragmentation patterns in some cases.

First Report of the Photosynthetic Dinoflagellate Genus Azadinium in the Pacific Ocean: Morphology and Molecular Characterization of Azadinium cf. poporum

A strain of a dinoflagellate belonging to the genus Azadinium was obtained by the incubation of sediments collected from Shiwha Bay, Korea, which is the first outside of northern Europe and furthermore from the Pacific Ocean to be reported.

First detection of species of the potentially toxic genus Azadinium (Amphidomataceae, Dinophyceae) in tropical coastal waters of Brazil

In fall 1995, during a survey in Abrolhos coral reef system, significant densities of small thecate dinoflagellates were detected, and analysis of this material in scanning and transmission electron microscopy confirmed the presence of four taxa assigned to the potentially toxic genus Azadinium.

Identification of Azadinium poporum (Dinophyceae) in the Southeast Pacific: morphology, molecular phylogeny, and azaspiracid profile characterization

This is the first confirmation of the presence of AZA producing Azadinium in the Chilean coastal area and underlines the risk ofAZA shellfish and concomitant human contamination episodes in the Southeast Pacific region.

Azadinium caudatum var. margalefii, a poorly known member of the toxigenic genus Azadinium (Dinophyceae)

Abstract Azadinium caudatum is a poorly known planktonic dinoflagellate, which mainly attracts attention due to the occurrence of many toxigenic species in the genus Azadinium. The availability of



Azadinium obesum (Dinophyceae), a new nontoxic species in the genus that can produce azaspiracid toxins

DNA sequence and phylogenetic analysis elucidates and supports the separation (but close affinity) of A. obesum and A. spinosum, and further validates the recently erected genus Azadinium Elbrächer et Tillmann.

Azadinium spinosum gen. et sp. nov. (Dinophyceae) identified as a primary producer of azaspiracid toxins

This study represents the first description and confirmation of a new dinoflagellate species capable of producing AZA and is thus an important advance in surveillance programmes for toxigenic microalgae and toxins of human health significance.


A new species of the dinoflagellate genus Alexandrium, A. tamutum sp. nov., is described based on the results of morphological and phylogenetic studies carried out on strains isolated from two sites

An SEM study of Amphidoma nucula (dinophyceae) and description of the thecal plates in A. caudata

First identification of azaspiracid and spirolides in Mesodesma donacium and Mulinia edulis from Northern Chile.

A fine‐structural survey of dinoflagellate pyrenoids and food‐reserves

About half of the 30 or so species of dinoflagellates examined by electron microscopy have been found to possess distinct pyrenoids associated with chloroplasts and having a granular proteinaceous

Ubiquitous 'benign' alga emerges as the cause of shellfish contamination responsible for the human toxic syndrome, azaspiracid poisoning.

Correlation with occurrence of OA and DTX2, showed both toxin families could appear simultaneously in Moroccan mussels, but maximal concentrations found were always separated in time.
