Bloom-forming cyanobacteria and dinoflagellates in five Argentinian reservoirs: Multi-year sampling

Water Biology and Security
Harmful algal blooms are important threats to reservoir condition. Over a 15-year period, we sampled five Argentinian reservoirs to identify the responsible species for harmful algal blooms and determine the water quality factors driving their occurrence.

Periphyton effects on bacterial assemblages and harmful cyanobacterial blooms in a eutrophic freshwater lake: a mesocosm study

Scientific Reports, 2017
Periphyton comprises a broad range of autotrophic and heterotrophic organisms that grow on submerged surfaces in aquatic environments. To investigate the ecological roles of periphyton and their symbiotic bacterial assemblages related to the control of ...

Endotoxins and Biological Implications—Review

Public Health Challenges, Volume 5, Issue 4, December 2026.
Graphical overview of endotoxin sources, exposure routes, biological effects, detection methods, and routes of elimination. ABSTRACT Endotoxins, also known as lipopolysaccharides (LPSs), are structural components of the outer membrane of Gram‐negative bacteria and some cyanobacteria.

Microbial diversity, genomics, and phage–host interactions of cyanobacterial harmful algal blooms

mSystems
The occurrence of cyanobacterial harmful algal blooms (cyanoHABs) is related to their physical and chemical environment. However, less is known about their associated microbial interactions and processes.

Acute toxicity of fine and coarse copper sulfate crystals to planorbid snails in experimental catfish ponds

Journal of the World Aquaculture Society, Volume 57, Issue 6, December 2026.
Abstract Bolbophorus damnificus, a digenetic trematode infecting ictalurid catfish, causes substantial economic losses in commercial aquaculture through a parasite‐induced anemia, leading to poor performance and increased susceptibility to secondary bacterial infections.

Plant NAOGAT (ArgJ) Structure Reveals Mechanism of Ornithine Biosynthesis, Preference for Acetylornithine and Susceptibility to Mangotoxin

Plant, Cell &Environment, Volume 49, Issue 12, Page 10283-10300, December 2026.
ABSTRACT Arginine metabolism in plants is targeted by phytopathogens such as Pseudomonas syringae strains, which produce toxins that affect enzymes of plant arginine metabolism, causing devastating infections in crops. In this work, the structural and functional properties of plant N‐acetylornithine glutamate acetyltransferase (NAOGAT), the key ...

Cyanobacterial blooms and animals [PDF]

Cyanobacteria (also called blue-green algae) are microscopic organisms that can be found naturally in all types of water (fresh; marine; or a combination, which is also called brackish).

Community Structure and Toxicity Potential of Cyanobacteria during Summer and Winter in a Temperate-Zone Lake Susceptible to Phytoplankton Blooms

Toxins
Cyanobacterial blooms are increasingly common during winters, especially when they are mild. The goal of this study was to determine the summer and winter phytoplankton community structure, cyanotoxin presence, and toxigenicity in a eutrophic lake ...

Cyanobacteria as biological drivers of lake nitrogen and phosphorus cycling

Ecosphere, 2015
Here we draw attention to the potential for pelagic bloom‐forming cyanobacteria to have substantial effects on nutrient cycling and ecosystem resilience across a wide range of lakes.
