Blooms dominated when both NO3 and NH4 levels were high, these organisms can appear small. Since 1998, recurrent toxic (Paralytic Shellfish Poisoning) blooms of Alexandrium catenella occur in Thau lagoon (French Mediterranean coast) during spring and/or autumn. Animals control the growth and toxicity of Alexandrium species that produce toxins that cause paralytic poisoning. In the present study, laboratory experiments were conducted to study the effect of different concentrations of Alexandrium catenella (dinophyta) on Aurita sp. Little is known of their gametes because they are indistinguishable from vegetative cells by morphology or ploidy. We conducted a 4-year survey in King Harbor, CA, to investigate the seasonal dynamics of Alexandrium catenella and the presence of a particulate saxitoxin (STX), the parent compound of the PSTs. 3.

A. catenella occurs in Puget Sound and causes PSP. Additionally, histopathological and stress responses (through heat-shock protein [hsp70] induction), as well as accumulation of Paralytic Shellfish Poisoning (PSP) toxins, were monitored on scallops after 3 and 6 days of exposure to A. catenella. Recognized as the most geographically widespread algal-related shellfish poisoning syndrome, PSP constitutes a serious human illness caused by the ingestion of seafood contaminated with saxitoxi 1,5).

WebThe dinoflagellate genus Alexandrium comprises most of the toxic bloom-forming species producing paralytic shellfish toxins (PSTs) in the sea. Everyone can see that a cow eats grass and hay, a lion attacks and eats a gazelle, and an oak tree's leaves convert the sun's light into glucose for energy, etc. These protists are referred to as mixotrophs since they can both consume organisms/organic materials and perform photosynthesis in order to get food: It's a "mix" of both autotrophic and heterotrophic ability.
