Paralytic Shellfish Poisoning Toxins: Biochemistry and Origin
Plankton feeders such as bivalves often become toxic. Human consumption of the toxic bivalve causes severe food poisoning, including paralytic shellfish poisoning (PSP) which is the most dangerous because of the acuteness of the symptoms, high fatality and wide distribution throughout the world. Accumulation of PSP toxins in shellfish has posed serious problems to public health and fisheries in...
متن کاملPossible association of marine bacteria with paralytic shellfish toxicity of bivalves
Significant amounts of paralybc shellfish toxins (PSP toxins) were detected in particles in the slze fraction 0.45 to 5 pm in seawater from Ofunato Bay, Japan, collected at a time when the toxicity of scallop increased in the absence of the causative organism Protogonyaulax tarnarensis. Toxin in the same fraction was negligible when scallop toxicity was decreasing. PSP toxins were also detected...
متن کاملImmunoassay methods for paralytic shellfish poisoning toxins.
The current status of immunochemical techniques for analysis of paralytic shellfish poisoning (PSP) toxins is summarized. Important aspects regarding production of the biological reagents necessary for immunochemical methods, the characteristics of polyclonal and monoclonal antibodies against saxitoxin and neosaxitoxin, and the importance of test sensitivity and specificity are discussed. Appli...
متن کاملCharacterization of Satellite DNA from Three Marine Dinoflagellates (Dinophyceae): Glenodinium sp. and Two Members of the Toxic Genus, Protogonyaulax.
Using CsCl-Hoechst dye or CsCl-ethidium bromide gradients, satellite and nuclear DNAs were separated and characterized in three marine dinoflagellates: Glenodinium sp., and two toxic dinoflagellates, Protogonyaulax tamarensis and Protogonyaulax catenella. In all three dinoflagellates, the lowest density fraction, satellite DNA(1), hybridized to chloroplast genes derived from terrestrial plants ...
متن کاملEvidence for production of paralytic shellfish toxins by bacteria associated with Alexandrium spp. (Dinophyta) in culture.
A substantial proportion of bacteria from five Alexandrium cultures originally isolated from various countries produced sodium channel blocking (SCB) toxins, as ascertained by mouse neuroblastoma assay. The quantities of SCB toxins produced by bacteria and dinoflagellates were noted, and the limitations in comparing the toxicities of these two organisms are discussed. The chemical nature of the...
