Validation of a Droplet Digital PCR (ddPCR) Assay to Detect Cyanobacterial 16S rDNA in Human Lung Tissue

open access: yesToxics, 2023
Cyanobacteria produce a variety of secondary metabolites, including toxins that may contribute to the development of disease. Previous work was able to detect the presence of a cyanobacterial marker in human nasal and broncoalveolar lavage samples ...

Multi-Toxin Occurrences in Ten French Water Resource Reservoirs

open access: yesToxins, 2018
Cyanobacteria are known to produce a wide array of metabolites, including various classes of toxins. Among these, hepatotoxins (Microcystins), neurotoxins (Anatoxin-A and PSP toxins) or cytotoxins (Cylindrospermopsins) have been subjected to numerous ...

Negative Effects of Cyanotoxins and Adaptative Responses of Daphnia

open access: yesToxins, 2022
The plethora of cyanobacterial toxins are an enormous threat to whole ecosystems and humans. Due to eutrophication and increases in lake temperatures from global warming, changes in the distribution of cyanobacterial toxins and selection of few highly ...

Cyanobacteria, microcystins and cylindrospermopsin in public drinking supply reservoirs of Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2014
Brazil has a history of blooms and contamination of freshwater systems by cyanobacterial toxins. The monitoring relevance of toxins from cyanobacteria in reservoirs for public supply is notorious given its high toxicity to mammals, included humans beings.

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

open access: yesЖурнал 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

Characterization of phytoplankton by pigment analysis and the detection of toxic cyanobacteria in reservoirs with aquaculture production

open access: yesAquaculture Environment Interactions, 2018
The intensified use of water bodies and reservoirs for aquaculture production has increased the need for monitoring and early warning of toxins from cyanobacteria. To minimize effects from toxins, simple and fast analytical monitoring methods are crucial.

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.
