Problem: Scientists once hoped that Koch's postulates would help find the cause of all human diseases. However, their hopes proved unfounded.
Consider the following human diseases and conditions. Use internet or textbook resources to describe the cause(s) of each one. Based on that etiology, explain why Koch's postulates could OR could not have been used to identify the cause of that disease or condition. Feel free to use an additional sheet of paper. (a) Cholera (b) Pneumonia (c) Scurvy (d) AIDS (e) Down syndrome
