And it was "aerosolized." The word "weaponized" was not used, but it didn't need to be, this official says. It was understood that these anthrax spores would hang...
...MAKES YOU SICK Once inside the body, anthrax bacteria emerge from their dormant spore phase and begin to reproduce and spew out toxins, which poison tissues and cause organs to fail. Inhaling spores is most likely to result in death because the germs burrow into lung tissue, where they come in close contact with lymph vessels. These serve as the body's liquid highway, transporting nutrients, debris--and bacterial toxins--throughout the body...
...Tucker:Anthrax is a bacterium, but when it?s exposed to air, it forms a spore resembling a seed. The spore is very rugged, and very persistent. If it?s introduced into the soil in that spore form, it can live for years, even decades. That?s the form it would probably be take if it were used as a biological weapon - spores introduced into the air via some delivery method...
Serendipity intervenes: in the London summer of 1928, an open window in a hospital lab lets in a spore that settles on a staphylococcus-culture dish left unwashed. A mold grows and contaminates the staphylococcus. The lab user returns. Because he's bacteriologist Alexander Fleming, and because his lab has not been cleaned, penicillin is discovered...
