Yep, and they MAY *occsioanlly* drive one or two species to extinction,
if the species is already under stress.  But for catasrtrophic diseases
to wipe out entire faunas?  I doubt it.

In general diseases are *too* selective to account for mass extinctions.
(This is, of course, why Bakker suggests multiple waves of diseases).
