Yesterday I spent some time with a woman who does phase contrast, which is the new and improved way of looking at blood (so it's better than brightfield and darkfield microscopy, and you don't have to stain the sample). The magnification is 5000x. I've always wanted to have this done so I can see what my red blood cells and serum are up to. I learned a lot.
Here you can see red blood cells, with some rouleaux (sticking together, on top of each other). Though mine's not the worst to be seen by any means, the rouleaux could signify an active infection, or gut inflammation. The small dancing speck toward the end of this clip is a triglyceride.
And here, what looks like a spirochete that has exited a red blood cell.
And here, the creepiest. It's a biofilm with 6 spirochetes attached. It's in the middle of the screen, a little to the right, but you can't see it very well here. I will upload another video of it soon.
