Question: The hypothetical OxyA protein is a surface protein that may have a role in attachment to the surface of the intestinal epithelium but there is evidence that it has a role in invasion. Assume there is a suitable mouse model and that attachment can be demonstrated using human cell culture lines. Describe how you would use a molecular version of Koch’s postulates to support the hypothesis that the OxyA protein is a virulence factor. Be sure to describe what kind of results you would expect for each step in the process.
