The genus of the intestinal threadworms is the strongyloid genus. Threadworms are most commonly in the small intestines and kidneys of their hosts. These are typically found in animals that chew their cud. Examples of these animals include llamas, alpacas, and deer. Threadworms in specifically, however, like humans. They get their name from the fact that they look like threads of cotton.
They are gotten by touching something that is contaminated with the eggs of the worms, and then sticking the contaminated fingers into one’s mouth. Strict hygiene measures should be followed to get rid of them if someone suspects they have threadworms. Often, many people will not realize they have threadworms. They’ll have an itchy bottom, but no other symptoms of an infection.
