Immunomodulatory Effects of Pure Cylindrospermopsin in Rats Orally Exposed for 28 Days

Toxins, 2022
Cylindrospermopsin (CYN) is a ubiquitous cyanotoxin showing increasing incidence worldwide. CYN has been classified as a cytotoxin and, among its toxic effects, its immunotoxicity is scarcely studied.

An Analytical Method for Simultaneous Measurement of Various Cyanotoxins Using Stable Isotope-Labeled Surrogates and a Microbial Flora Analysis to Assign Each Cyanotoxin to its Source

Journal of Water and Environment Technology, 2022
Cyanotoxins produced by blue-green algae in lakes are among the most serious threats to water quality worldwide. As global warming rapidly extends the locations and timing of blue-green algae blooms, a simple and accessible method for ...

Cyanobacteria and Cyanotoxins Occurrence and Removal from Five High-Risk Conventional Treatment Drinking Water Plants

Toxins, 2015
An environmental protection agency EPA expert workshop prioritized three cyanotoxins, microcystins, anatoxin-a, and cylindrospermopsin (MAC), as being important in freshwaters of the United States. This study evaluated the prevalence of potentially toxin

Evaluation of the Removal and Effects of Cylindrospermopsin on Ripened Slow Sand Filters

Toxins, 2023
The occurrence of toxic blooms of cyanobacteria has been a matter of public health interest due to the cyanotoxins produced by these microorganisms. Cylindrospermopsin (CYN) is a cyanotoxin of particular concern due to its toxic effects on humans.

Multi-Omic Assessment of Microbial Communities and Their Polyketide Biosynthetic Potential Across Abyssal Sediments. [PDF]

Environ Microbiol
Abyssal sediments were assessed for taxonomic diversity and polyketide biosynthetic potential and compared to metagenomic and metabolomic assessments of the same sediments. Biodiversity differences were documented across biogeochemical regimes with the results providing baseline awareness of what might be lost should deep‐sea microbiomes be disrupted ...

Multiple Stressors at the Land-Sea Interface: Cyanotoxins at the Land-Sea Interface in the Southern California Bight

Toxins, 2017
Blooms of toxic cyanobacteria in freshwater ecosystems have received considerable attention in recent years, but their occurrence and potential importance at the land-sea interface has not been widely recognized.

Physiological and Metabolic Responses of Marine Mussels Exposed to Toxic Cyanobacteria Microcystis aeruginosa and Chrysosporum ovalisporum

Toxins, 2020
Toxic cyanobacterial blooms are a major contaminant in inland aquatic ecosystems. Furthermore, toxic blooms are carried downstream by rivers and waterways to estuarine and coastal ecosystems. Concerning marine and estuarine animal species, very little is

Allelopathic Potential of the Cyanotoxins Microcystin-LR and Cylindrospermopsin on Green Algae

Plants, 2023
Allelopathic interactions are widespread in all aquatic habitats, among all groups of aquatic primary biomass producers, including cyanobacteria. Cyanobacteria are producers of potent toxins called cyanotoxins, whose biological and ecological roles ...

Neurotoxicity induced by microcystins and cylindrospermopsin: A review [PDF]

Science of The Total Environment, 2019
Microcystins (MCs) and cylindrospermopsin (CYN) are among the most frequent toxins produced by cyanobacteria. These toxic secondary metabolites are classified as hepatotoxins and cytotoxin, respectively. Furthermore, both may present the ability to induce damage to the nervous system.

Nutrient-driven regulation of saxitoxin gene expression and toxin production in Raphidiopsis raciborskii (Cyanobacteria). [PDF]

J Phycol
Abstract Raphidiopsis raciborskii is a diazotrophic cyanobacterium, globally distributed in aquatic environments and known for forming toxic blooms, thereby affecting ecosystem services. South American strains are producers of saxitoxins, potent neurotoxins harmful to humans and animals.
