[Histonet] Identification of bacteria on an acrylic lens prosthesis

I'm certified in EM. My suggestion would be to use SEM as opposed to TEM. The scanning electron microscope (SEM) can also be useful to reveal morphological features of isolated organisms as well as for diagnosis.  There are numerous articles citing this technique. I believe the UC Berkley has an SEM in their lab.    I hope this helps.  Terri

Subject: [Histonet] Prosthetic lens processing, cutting?

Hi all,
Does anyone have any experience with embedding an acrylic prosthetic lens for EM, or any other way ? We have a case where they wanted EM on a lens to identify a  specific bacteria. We have never done it and it would take some work to figure it out. Also, I told them that unless there is some morphologic marker for the bacteria, EM would not help much identifying it.
Any ideas?
Any labs that handle this kind of thing? They are willing to send it out.
