Below is a list of known cyanobacteria and the toxins they produce.

Genus Toxins produced
Anabaena Anatoxins, Microcystins, Saxitoxins
Anabaenopsis Microcystins
Aphanizomenon Saxitoxins, Cylindrospermopsins
Cylindrospermopsis Cylindrospermopsins, Saxitoxins
Hapalosiphon Microcystins
Lyngbya Aplysiatoxins, Lyngbyatoxin a
Microcystis Microcystins
Nodularia Nodularin
Nostoc Microcystins
Phormidium (Oscillatoria) Anatoxin
Planktothrix (Oscillatoria) Anatoxins, Aplysiatoxins, Microcystins, Saxitoxins
Schizothrix Aplysiatoxins
Trichodesmium yet to be identified
Umezakia Cylindrospermopsin

Some of these toxins, especially saxitoxins are considered bioweapons that act on the brain and nervous system. In biochemical form, saxitoxins are easily dissolved into water and can be ingested or *inhaled*. http://www.globalsecurity.org/wmd/intro/bio_saxitoxin.htm


Almost looks like the makings for a "Zombie Apocalypse".
Oddly enough saxotoxin is also produced by pufferfish which has been cited as a key ingredient for voodoo zombie mixtures... http://writersforensicsblog.wordpress.com/2010/04/22/more-raising-the-dead-ma...


Anyways...

Similar intoxications can follow the growth of certain algae during “red tides.” You know... when the waters turn to "blood"... Not all cyanobacteria are red or green, but come in other colors.

Here I have collected some of what I suspect are the toxin producing culprits from the above list:
Trichodesmium:

These aren't random or even all the findings... Perhaps we've been treating for something entirely different than what the real problem is? I'm not sure, but here comes a tidal wave of brainfog now...
