By definition a parasite is harmful. Any number of diseases that you can think of caused by bacteria, viruses, worms, lice or amoebae are parasites. Their job is not to live with you but to use you as a source of food and to make more parasites like themselves. Some parasites do live a long time on you or in you but they always cause harm.
