Eric and Mike and others.
I have done this a number of times and it works well for me. I talked
about this a bit on an earlier post. See:
I use a sharp Swiss army knife and scrape hard right above the
eyebrows. I then put the scrappings on the knife into
a drop of immersion oil. I would then add a coverslip. Look near the
pieces of skin They look like tiny worms but it is
neat to see the eight legs move.
It is possible I have a bit higher infestation than some (I grew up in
East Africa), but I suspect most of us could get it.
Actually I had a student scrape while I pulled my skin tight and them
put it on a microscope that had a video on it. It is neat to wee the
eight legs waving. Good luck.
Feel free to send an e-mail or phone if you have questions.
