Infectious Dose Problem 9. You want to know the ID50 of a microbe you have recovered from a casserole. You are able to culture it and generate a prep that contains 10 microbes per ml. You run a challenge study with 100 mice where you feed each mouse 50ul of the prep. Within 3 days you record the number of sick mice and you find that 30 of the mice are showing signs of being sick. How can you estimate the ID50, and what is that estimate? (Hint: quickly find the percentage of mice that are infected and then just use a ratio)
