Snake increase resistance, but compromises for slower movement without toxin (more exposed to other predators)- predators adpating to prey. Bubonic plague, influenza antibiotics new strain tuberculosis in russian prisons. Most harmful bacteria is water-borne (cholera)- can be quickly spread- want to grow these. Becomes active disease in the malnuritioned; microbes in body become drug resistant after irresponsible treatment course; spread enhanced by our availability to travel.
