: "Transmission can be effected by oral or parenteral inoculation but is

: through small ulcerations in the intestinal mucosa. Thus oral transmission
: of CJD, while rare, is possible.
Okay, I'm not in the field (though brain science has always been of
interest to me), but can anyone give me the history of CJD: Who identified
it, how (case histories) it was first identified, and so on? I realize
this group is largely composed of knowledgible folks who may take offense
as my use and request of the bandwith here, but I'd be very appreciative.
