Turns out you can take pics with a digital camera through a microscope lens. Check out the dog louse. This creepy crawlie came in on a new families puppy recently.
The yellowish dot on the slide below is what it looks like actual size. They are slightly larger than a flea.
This is scabies, also known as sarcoptic mange mites. Not visible with the naked eye.
And urine crystals. With some bacteria and red blood cells thrown in for fun.
I also get to look at fecal samples but haven't taken a photo of that yet. I'm sure there will be some interesting parasites to show eventually.
