**** You may be right Marshall.  But what is being speculated now is that the 
parasites are hitching a ride on white blood cells.  If that's the case, then 
there is no breech.  You make an interesting point though -- so tell me, how 
would the blood-brain barrier become damaged?  And how would it go about 
healing?  MA
