We tried very hard not to do CJD cases if we could help it, as I recall any

Correction, due to years of formalin abuse, it was 1 hour in concentrated
formic acid. We then processed and cut them with all other cases. A few cases
slipped through with just formalin fixation and additional precautions needed
to be taken. That said the easiest and primary route of infe
Actually it has been proven that formalin will inactivate Ebola, as well as
other hemorrhagic fever viruses.

Back in the 80 NIH did extensive studies on CJD, their protocol requires 24
hours in formalin, 24 hours in formic acid, followed by 48 hours in formalin,
then paraffin processing. Worked with CJD at Frederick Cancer Research in
collaboration with the group from NIH. If I find the publications
If formalin didn't kill CJD, what did you use? Just curious.

Well said Pam, it is just assumed that formalin will eliminate the biohaz for
Ebola, I doubt if that has been conclusively proven yet, remember we only
discovered fairly recently that formalin fixation did not protect us from

All samples should be handled with universal precautions assuming they may be
infectious, formalin fixation is considered an eliminator of biologic hazard
for most things like Ebola, but then there is always CJD that it does not work
for. I would not be doing any frozen sections on samples with
Take Brett's advise and use that as guidleine. We don't know as much as we
should about these viruses. Pam

Our new Pathologist would like to see more yellow in the background of our Gram
stain. We use picric acid-acetone currently, which looks more pink than yellow
most times. So I'm wondering if a method using a Tartrazine counterstain would
be better.
Any thoughts?
