“We have given you, O Adam, no visage proper to yourself, nor endowment properly your own, in order that whatever place, whatever form, whatever gifts you may, with premeditation, select, these same you may have and possess through your own judgement and decision […] We have made you a creature neither of heaven nor of earth, neither mortal nor immortal as the free and proud shaper of your own being, fashion yourself in the form you may prefer.”
Oration on the Dignity of Man – Giovanni Pico della Mirandola

Escherichia coli is a bacteria that we have in the digestive tract and is perfectly harmless. There are other strains of this bacteria typical of some animals that can be pathogenic for us and cause anything from mild diarrhea to death. But, without bacteria, no life would be possible on the planet, nor men could travel to Mars.
