Dracunculus medinensis (Guinea worm, dragon worm, fiery serpent [1]) is a nematode that causes dracunculiasis, also known as guinea worm disease. [2] The disease is caused by the female [ 3 ] which, at around 80 centimetres (31 inches) in length, [ 4 ] is among the longest nematodes infecting humans. [ 5 ]
Dracunculiasis, also called Guinea-worm disease, is a parasitic infection by the Guinea worm, Dracunculus medinensis.A person becomes infected by drinking water contaminated with Guinea-worm larvae that reside inside copepods (a type of small crustacean).
Females of different species within the genus tend to look similar, and can rarely be distinguished on morphology alone. [1] The body of a fertilized adult female is almost completely filled by its uterus, distended with L1 larvae. [1] Adult female Dracunculus worms are noted for their extraordinary length, with some growing up to 100 ...

These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
Cyclops is intermediate host of dracunculiasis (guinea-worm disease) and fish tapeworm (Diphyllobothrium latum) infection. This disease can be passed to humans through drinking infected water. Dracunculiasis will rarely cause death but is a weakening disease. [4]
Soil-transmitted helminthiasis is the most prevalent neglected tropical disease. [76] The four major worm species responsible for soil-transmitted helminthiasis are Ascaris , Trichuris , the hookworms Necator americanus and Ancylostoma duodenale, and Strongyloides stercoralis. [77] There are 1.5 billion people currently infected. [77]
Platydemus manokwari, also known as the New Guinea flatworm, is a species of large predatory land flatworm. Native to New Guinea , it has been accidentally introduced to the soil of many countries, including the United States. [ 3 ]
