Re: Lymia (français and English)

Hi Lymia, I am afraid I am going to have to insist on my suggestion that you contact a Laboratory Technician if you are determined to continue with your plan to identify the bacteria that causes Lyme’s disease with a microscope.

75RR, what specific info would you like to know?
I suppose like most of us I would like to get a dry 60x someday, so the make + NA perhaps a link to where you got it if it is new. The usual suspects.

How did you manage to get the images for the stack? Was it not moving?
They do seem to spend most of their time twirling about, now and again they seem to rest, not sure why.
