Several of our readings in past weeks have been on the effects on health of a microbiota shift. One example is the study of malnourished Malawian twins who had developed kwashiorkor. Can Koch's postulates be extended to cover a community of microbes? Explain which of Koch's postulates were fulfilled and which were violated in this study. What experiment(s) did the scientists do to fulfill Koch's third postulate?

Secretase family of enzymes are central to the processing of amyloid precursor proteins (APP) associated with the development of Alzheimer's disease. They have garnered much attention over the years as a possible therapeutic target for the disease. Would targeting these enzymes for inhibition be an effective strategy for preventing the onset of Alzheimer's related amyloid plaque formation. If not, can you think of another approach that might be effective that doesn't necessarily involve targeting these enzymes?
