HELP! What kind of Parasite is this?

[Parasite101]

Can someone who works in a lab or has knowledge of parasites please help. The parasite is circled in red and I've added a strand of hair circled in blue.

They seem to be some sort of Worm. But nothing on Google images is showing anything.

Long story short but I can't keep my asking my Dr over and over again.

They seem uniformly straight and tapered, much like some kind of bristle as already mentioned. Have you tried bending one? Are they floppy/springy/rigid? They look like they'd snap rather than be bendy like something alive (or once alive and now dead)
