Exposure to cyanobacteria can result in gastro-intestinal and hayfever symptoms or pruritic skin rashes. [2] Exposure to the cyanobacteria neurotoxin BMAA may be an environmental cause of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), Parkinson's disease, and Alzheimer's disease.

Cyanobacteria can interfere with water treatment in various ways, primarily by plugging filters (often large beds of sand and similar media) and by producing cyanotoxins, which have the potential to cause serious illness if consumed. Consequences may also lie within fisheries and waste management practices.
Brown band disease, or Red band disease, probably caused by protozoa (possibly Helicostoma nonatum) and cyanobacteria. Rapid wasting, possibly caused by a fungus growing on areas damaged by the feeding of parrotfish Sparisoma viride. White band disease, the cause of this disease remains unknown.
Microcystis aeruginosa is a species of freshwater cyanobacteria that can form harmful algal blooms of economic and ecological importance. They are the most common toxic cyanobacterial bloom in eutrophic fresh water. Cyanobacteria produce neurotoxins and peptide hepatotoxins, such as microcystin and cyanopeptolin. [1]
White pox disease, caused by Serratia marcescens; Black necrosing syndrome, or Dark spots disease, probably fungal. Brown band disease, or Red band disease, probably caused by protozoa (possibly Helicostoma nonatum) and cyanobacteria. Rapid Wasting, possibly caused by a fungus growing on areas damaged by the feeding of the Stoplight parrotfish.
The biosynthesis of saxitoxin is well-defined in cyanobacteria, while within dinoflagellates it remains mostly unknown. Cyanobacterial saxitoxin biosynthesis has been studied in radioisotope tracing experiments, and turns out to be highly complex, involving many steps, enzymes and chemical reactions.
Some kinds of blue-green algae (cyanobacteria) create neurotoxins, hepatoxins, cytotoxins or endotoxins that can cause serious and sometimes fatal neurological, liver and digestive diseases in humans. Cyanobacteria grow best in warmer temperatures (especially above 25 degrees Celsius), and so areas of the world that are experiencing general ...
Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and are often beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
