It looks like white rats, except with many different colors like black hooded and husky! Try searching google, "fancy rat" "dumbo rat" "hooded rat" and you'll get many pictures. I can't post pictures here yet for examples since I am still a new member though.

No, domesticated rats don't carry any diseases. From what I know, you can get leptospirosis from being in contact with urine, but if you clean the cage every week this shouldn't be a problem.
