Helminthiasis, also known as worm infection, is any macroparasitic disease of humans and other animals in which a part of the body is infected with parasitic worms, known as helminths. There are numerous species of these parasites , which are broadly classified into tapeworms , flukes , and roundworms .
Many of the worms referred to as helminths are intestinal parasites. An infection by a helminth is known as helminthiasis, helminth infection, or intestinal worm infection. There is a naming convention which applies to all helminths: the ending "-asis" (or in veterinary science: "-osis") is added at the end of the name of the worm to denote the ...

Cochliomyia hominivorax, the New World screwworm fly, or simply screwworm or screw-worm, is a species of parasitic fly that is well known for the way in which its larvae (maggots) eat the living tissue of warm-blooded animals.
Drugs are frequently used to kill parasites in the host. In earlier times, turpentine was often used for this, but modern drugs do not poison intestinal worms directly. Rather, anthelmintic drugs now inhibit an enzyme that is necessary for the worm to make the substance that prevents the worm from being digested. [citation needed]
Scientists have found over a dozen parasitic worms in the eyes of a black bear, renewing fears that humans could face an emerging danger from the tiny worms that can cause blindness.
In humans, infections are caused by two main species of roundworm, belonging to the genera Ancylostoma and Necator. In other animals the main parasites are species of Ancylostoma . Hookworm is closely associated with poverty because it is most often found in impoverished areas, and its symptoms promote poverty through the educational and health ...
Research on the worms began more than 15 years ago at Sam Houston State University when Patrick J. Lewis, a professor there, led a research trip to Botswana with students.
