That is, very small quantities of such an infectious agent can spark a galloping inflammation in the infected animal, and that can ultimately lead to death. That effect did occur, pretty much... it had been under discussion for a long time, and it... classically, it's called horror autotoxicus,
if I'm getting the Latin pronunciation right, meaning, "horror, when an organism directs its forces against itself and toxifies itself."
Such a... such agents were made on the basis of bacteria and the smallpox virus. In the case of the smallpox virus, the effect was exceedingly powerful, that is, animals that practically never died from the smallpox virus inevitably died later on from an autoimmune disease, which came on the heels of... of the viral disease.
