Worldwide development of cyanobacterial blooms has significantly increased in marine and continental waters in the last century due to water eutrophication. This phenomenon is favoured by the ability of planktonic cyanobacteria to synthesize gas vesicles that allow them to float in the water column. Besides, benthic cyanobacteria that proliferate at the bottom of lakes, rivers and costal waters form...
From 2001 to 2005, numerous cases of seafood poisonings were reported in a tribe from Lifou (Loyalty Islands Province, New Caledonia) of which 35 were thoroughly examined. Observations outlined by the epidemiological and clinical data (including severity and rapid onset of certain symptoms following consumption of either giant clams (Tridacna spp.) or grazing and molluscivorous fish together with...
Anatoxin-a (ANTX) and homoanatoxin-a (HANTX), neurotoxins exclusively produced by cyanobacteria (LD 50 200–250μgkg −1 , i.p. mouse), are agonists of the nicotinic acetylcholine receptors (nAChRs) to which they tightly bind. We have exploited the high affinity of these neurotoxins for the nicotinic receptors to develop a non-radioactive ligand-binding assay using Torpedo electrocyte...
