Is the environmental risk posed by DDT an acceptable cost in the battle to control malaria? Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes. It is preventable and curable.

In a series of infection experiments, a researcher discovers that the ID50 value for the infectious bacterium Parasiticum mucoides is 100, and that the ID50 for another infectious bacterium, Donoteatum thisbacterium, is 15,000.  Given these data, a person exposed to 1,000 bacteria of each type would be more likely to be infected by which bacterium? Group of answer choices There is no way to know given the information provided Both infections are equally likely Parasiticum mucoides Donoteatum thisbacterium
