Hi! Great post outlining E. coli, I actually received my bachelors degree in microbiology so I know a fair bit about it! I just want to point out that the shiga toxin, produced by the Shigella genus of bacteria, can cause a victim to develop dysentery. The E. Coli you refer to actually produces shiga-like toxins, not shiga toxin itself. In addition, I want to point out that E. coli does not just cause one type of disease or ailment, different strains of the species may cause different complications (for example the strain with shiga-like toxin may cause a patient to have dysentery-like symptoms). Regardless, I'd be interested if you posted more about bacteria in the future, and if you want to learn more on the subject, add me on steemit.chat and I can recommend some great resources for you! :)
