Anisakis ( ) is a genus of parasitic nematodes that have life cycles involving fish and marine mammals. They are infective to humans and cause anisakiasis. People who produce immunoglobulin E in response to this parasite may subsequently have an allergic reaction, including anaphylaxis, after eating fish infected with Anisakis species.

Trichuris (synonym Trichocephalus), often referred to as whipworms or the silent serpent (which typically refers to T. trichiura only in medicine, and to any other species in veterinary medicine), is a genus of parasitic helminths from the roundworm family Trichuridae. The name whipworm refers to the shape of the worm; they look like whips with wider "handles" at the posterior end.

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, and is common in areas with poor access to adequate water, sanitation, and hygiene. 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 healt

The Onchocercidae are a family of nematodes in the superfamily Filarioidea. This family includes some of the most devastating human parasitic diseases, such as lymphatic filariasis, onchocerciasis, loiasis, and other filariases.

Metastrongylus is a genus of nematodes of the family Metastrongylidae, usually found as lungworms in pigs and sometimes causing parasitic bronchitis. It causes a disease called metastrongylosis.

Strongyloides (from Greek strongylos, round, + eidos, resemblance), anguillula, or threadworm is a genus of small nematode parasites, belonging to the family Strongylidae, commonly found in the small intestine of mammals (particularly ruminants), that are characterized by an unusual lifecycle that involves one or several generations of free-living adult worms.

Onchocerca is a genus of parasitic roundworm. It contains one human parasite – Onchocerca volvulus – which is responsible for the neglected disease Onchocerciasis, also known as "river blindness" because the infected humans tend to live near rivers where host black flies live. Over 40 million people are infected in Africa, Central America, and South America. Other species affect cattle, horses, etc.

Strongyles (from Greek strongulos 'round'), or alternatively, strongyls, are nematode worms of the family Strongylidae, order Strongylida. They are often parasitic in the gastrointestinal tract of mammals, especially grazers such as sheep, cattle, and horses.

Mansonella is a genus of parasitic nematodes. It includes three species that are responsible for the disease mansonelliasis: Mansonella ozzardi, M. perstans, and M. streptocerca. A potential fourth species has been identified in Gabon in 2015 and proposed as a new species Mansonella sp. "DEUX". Whole-genome sequences from Mansonella perstans, Mansonella ozzardi, and the newly proposed species Mansonella sp. "DEUX" have been assembled.

Bunostomum is a genus of nematodes of the small intestine of ruminants and camelids. Important species include B. phlebotomum in calves and B. trigonocephalum in lambs. The worms are stout and measure in length. Young animals are most commonly affected and only several hundred worms are necessary to cause morbidity. Adults often carry worms without showing clinical signs.

Brugia is a genus for a group of small roundworms. They are among roundworms that cause the parasitic disease filariasis. Specifically, of the five species known, Brugia malayi and Brugia timori cause lymphatic filariasis in humans; and Brugia pahangi and Brugia patei infect domestic cats, dogs and other animals. Brugia buckleyi specifically infects the Indian hare (Lepus nigricollis singhala). They are transmitted by the bite of mosquitos.

Eucoleus is a genus of nematodes belonging to the family Capillariidae. Dwelling primarily in the airways of foxes, it can be found worldwide in dogs and cats.
