vQ, (01)
I think Barry has straightened me out on the issue overall. I was using
infectivity as a property of physiology rather than reducing physiology to
equate to infectivity. In fact, infectivity is difficult to talk about in
terms of a single entity given that both the infecting agent and the
recipient of the infection must both have properties that interact to allow
infection to occur. An example is the issue of Parvo B19 virus infection in
humans. If the p antigen is absent on the red cell surface, the virus cannot
infect the cell, so 10% of the population is immune naturally. (02)

That infectivity is determined by morphology does seem to me break the
barrier between anatomy and physiology. And also, any microorganism
that is infectious is so in virtue of its having a particular structure,
I do not find this applicable to prions only. Furthermore, you should
probably not reduce the physiology of prions to their infectivity. If
we can talk about the physiology of prions at all; Physiology is the
study of the mechanical, physical, and biochemical functions of *living
organisms*. (06)
