While not the easiest thing to see, mites can be visible on the bearded dragons skin. Parasitic infections, usually not visible(like pinworms or coccidia). Personally, I have yet to see any kites on my beardies skin. Now that I think of it, my beardy is overdue for a vet check, time to spend some big bucks.... Oh how I love doing that :? Hopefully he has nothing but I've noticed some pretty runny poop lately.
