Cyanotoxin Occurrence and Diversity in 98 Cyanobacterial Blooms from Swedish Lakes and the Baltic Sea [PDF]

Marine Drugs
The Drinking Water Directive (EU) 2020/2184 includes the parameter microcystin LR, a cyanotoxin, which drinking water producers need to analyze if the water source has potential for cyanobacterial blooms.

Revisiting the HPLC-FLD Method to Quantify Paralytic Shellfish Toxins: C3,4 Quantification and the First Steps towards Validation

Toxins, 2022
Paralytic shellfish toxins (PSTs) are a large group of biotoxins that cause paralytic shellfish poisoning. Their appearance in natural waters and their ingestion by aquatic species have a huge socio-economic impact, whereby their monitoring is of the ...

A Year of Bio-Monitoring (2021): Presence of Algae of the Genus Alexandrium, Dinophysis, Prorocentrum and Non-Compliance for Paralytic Toxins and Lipophilic Toxins in Bivalve Mollusks Bred in Sardinia (W Mediterranean Sea)

Journal of Marine Science and Engineering, 2022
Bivalve mollusk production represents the principal aquaculture activity in Sardinia (40°03′ N, 9°05′ E). In 2021, 859 water samples and 1270 mollusk samples were analyzed.

From the sxtA4 Gene to Saxitoxin Production: What Controls the Variability Among Alexandrium minutum and Alexandrium pacificum Strains?

Frontiers in Microbiology, 2021
Paralytic shellfish poisoning (PSP) is a human foodborne syndrome caused by the consumption of shellfish that accumulate paralytic shellfish toxins (PSTs, saxitoxin group).

The role of cyanotoxins in human and animal pathology (а review)

Журнал микробиологии, эпидемиологии и иммунобиологии, 2022
Cyanobacteria are the oldest and most widespread form of life on Earth. Many of them produce toxins that are dangerous to humans and animals. The review presents data on the distribution of toxin-producing cyanobacteria, the pathogenesis of the action of

Ecophysiological Aspects and sxt Genes Expression Underlying Induced Chemical Defense in STX-Producing Raphidiopsis raciborskii (Cyanobacteria) against the Zooplankter Daphnia gessneri

Toxins, 2021
Cyanobacteria stand out among phytoplankton when they form massive blooms and produce toxins. Because cyanotoxin genes date to the origin of metazoans, the hypothesis that cyanotoxins function as a defense against herbivory is still debated.

Cyanotoxins and water quality parameters as risk assessment indicators for aquatic life in reservoirs

Ecotoxicology and Environmental Safety, 2022
We assessed the extent of pollution in an essential public water supply reservoir (southeastern Brazil). An environmental monitoring study was performed at the Billings Reservoir (at the water catchment site) to assess the water quality in 2017, 2018 ...
