MAP: A Probable Cause of Crohn’s Disease

For the past 10 years I have been invited to give a lecture in a public health and epidemiology course, PHS-801, at the University of Wisconsin-Madison, School of Medicine, and Public Health as part of a series of lectures on disease causation, i.e., judging scientific evidence as to whether a pathogen is the cause of a disease. Every year the lecture was refined and updated with new information. On April 9, 2024, I again gave the lecture and this year had it recorded live. The 80-minute lecture is now posted on the Presentations page of my website: https://johnes.org/presentations-and-mini-lectures/ (scroll down to the last entry).

The lecture cites numerous peer reviewed scientific publications and in places is very technical. Most of those publications can be found on the page titled Zoonotic Potential: https://johnes.org/zoonotic-potential/. However, many parts of the lecture are quite understandable to non-scientists as the goal is to provide a “big picture” perspective on this global problem regarding MAP as a probable human pathogen.
