Amphidoma languida (Amphidomatacea, Dinophyceae) with a novel azaspiracid toxin profile identified as the cause of molluscan contamination at the Atlantic coast of southern Spain
For the first time azaspiracids were found along the Andalusian Atlantic coast. AZA levels in two shellfish species exceeded the EU regulatory limit. Amphidoma languida was isolated and identified as the causative species. Andalusian Am. languida had a novel AZA profile consisting of AZA-2 and the new AZA-43.
