The other theory (which makes sense in my experience with EPM, which is 
admittedly a bit limited) is that it only invades areas of the spinal 
meninges that are devitalized due to either accidental trauma or damage from 
spinal instability.  It shows up much more frequently in horses that are also 
more prone to the latter...
