Hookworms infected about 428 million people in 2015. [4] Heavy infections can occur in both children and adults, but are less common in adults. [2] They are rarely fatal. [6] Hookworm infection is a soil-transmitted helminthiasis and classified as a neglected tropical disease. [7]
Hookworms are intestinal, blood-feeding, parasitic roundworms that cause types of infection known as helminthiases. Hookworm infection is found in many parts of the world, [1] and is common in areas with poor access to adequate water, sanitation, and hygiene.
Ancylostoma duodenale is a species of the roundworm genus Ancylostoma.It is a parasitic nematode worm and commonly known as the Old World hookworm. It lives in the small intestine especially the jejunum [citation needed] of definitive hosts, generally humans, [2]: 307–308 [3] where it is able to mate and mature.
According to Lawrence, hookworms and whipworms -- parasitic worms, or helminths, that take up residence in the intestine -- induce a subdued inflammatory response more effectively than modern ...
Cutaneous larva migrans (abbreviated CLM) is a skin disease in humans, caused by the larvae of various nematode parasites of the hookworm family (Ancylostomatidae).The parasites live in the intestines of dogs, cats, and wild animals; they should not be confused with other members of the hookworm family for which humans are definitive hosts, namely Ancylostoma duodenale and Necator americanus.
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.
This is most severe in heavy hookworm infections, as Necator americanus and Ancylostoma duodenale feed directly on the blood of their hosts. Although the daily consumption of an individual worm (0.02–0.07 ml and 0.14–0.26 ml respectively) is small, the collective consumption under heavy infection can be clinically significant.
This hookworm is likely to be relatively safe, [42] although it can cause temporary gastrointestinal side effects, especially following the initial inoculation, or with increased doses. [10] High doses can also cause anemia. [29] The general ideal characteristics for a therapeutic helminth are as follows: [10] Little or no pathogenic potential
