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.

Historically, bacteria were first classified as plants constituting the class Schizomycetes, which along with the Schizophyceae (blue-green algae/Cyanobacteria) formed the phylum Schizophyta, [231] then in the phylum Monera in the kingdom Protista by Haeckel in 1866, comprising Protogens, Protamaeba, Vampyrella, Protomonae, and Vibrio, but not ...
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]

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]
Several species of cyanobacteria have been found associated with black band disease, [5] [6] the most well-known of which is Phormidium corallyticum. [7] Sulfide-oxidizing bacteria, dominated by Beggiatoa spp., [ 8 ] are present in well-developed bands and exhibit visible vertical migrations within the band matrix (Richardson, 1996; Viehman and ...
Blooms cause problems ecologically, economically, and in freshwater systems, adversely affect the quality of drinking water. [45] Spikes in cyanobacteria populations are usually brought on by nutrient increases due to run-off from fertilizers, dust, and sewage. [46] By killing hosts, cyanophages may help restore ecosystems to their natural balance.
While tetanus toxin is produced from Clostridium tetani, a spore forming bacteria found in soil, Tetanus is a paralytic disease that is global and commonly affects newborns as well as non-immunized individuals. Tetanus enters the body of organisms through wounds or skin breaks and can be found in manure, soil, and dust.
