  • RE: Dormant microbes and 'non-communicable' diseases
    • Douglas Kell, Professor of Systems Biology, University of Liverpool

    The piece by Finlay and colleagues (Science 367, 250-1, 2020) on the role of microbes in supposedly non-communicable diseases was badged as a 'hypothesis'. However, the evidence for a major involvement of microbes (and their products) in supposedly non-communicable diseases is massive. Such organisms are normally missed because they are in a dormant, non-growing state, and do not form colonies on typical growth media. Just a few references (1-6) will suffice to give a starting point to this very large literature.

    Because such dormant microbes do not fulfil Koch's postulates, it has also long been recognised that the postulates must be modified to provide a 'molecular' form. This was done many years ago by Staney Falkow (7,8).
