Dear netters: I need contacting any of you with current or past experience
on paraffin IHC (i.e. Streptavidin-biotin or ABC IHC) aimed at the
identification of VT + (=Verotoxigenic ) strains of Escherichia coli on
jejunal or ileal sections. I'm specially interested in listening to the
advise of those that have used primary antisera to Esherichia coli somatic
or "O" antigens, specially "O 111" to mark such bacteria when attached to
the epitelial apical border.
I'd be also interested in getting the exact processing protocol that has
been used in these cases.

Thank you in advance
