saxtoksiini
Saxtoksiin, or saxitoxin (STX), is a potent neurotoxin produced by certain marine dinoflagellates and freshwater cyanobacteria. It is the causative agent of paralytic shellfish poisoning (PSP) and can accumulate in filter-feeding shellfish such as clams, mussels, oysters, and scallops during algal blooms.
The toxin acts by blocking voltage-gated sodium channels, preventing the propagation of action potentials in nerves
Humans are mainly exposed through consumption of contaminated shellfish harvested during algal blooms. Symptoms typically appear
Ecology and public health considerations emphasize that saxtoksiin production is linked to environmental conditions such as
