Klamath Lake AFA, also called Klamath Lake Blue Green Algae and Klamath AFA (Aphanizomenon flos-aquae MDT14a), is a strain of Aphanizomenon flos-aquae. Small amounts of this cyanobacteria can be found in bodies of water worldwide, [1] but it is notable for growing prolifically in Upper Klamath Lake, Oregon.
Aphanizomenon flos-aquae is a diverse group of cyanobacteria with both toxic and non-toxic [1] [2] strains found in brackish and freshwater environments globally, including the Baltic Sea and the Great Lakes. Recent genome sequencing efforts have identified 18 distinct varieties [3] of Aphanizomenon flos-aquae, revealing its genetic complexity.
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
Members of the public and veterinarians should call 608-266-1120 or complete the online form Harmful Algae Bloom (HAB) Illness or Sighting Survey, F-02152 to report any blue-green algae blooms and ...

Anatoxin-a is toxic to the nerves in animals and is very lethal to humans with a lethal dose thought to be less than 5 mg. [12] Similarly to anatoxin-a, BMAAs are another type of neurotoxin that lingers inside animals for longer than anatoxin-a. It will keep affecting animals even after an algal bloom dies down.
The prefix cyan comes from the Greek κύανoς meaning "a dark blue substance", [19] and usually indicates any of a number of colours in the blue/green range of the spectrum. Cyanobacteria are commonly referred to as blue-green algae. Traditionally they were thought of as a form of algae, and were introduced as such in older textbooks.
