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.
Enoplea (enopleans) is a class, which with the classes Secernentea and Chromadorea make up the phylum Nematoda in current taxonomy. The Enoplea are considered to be a more ancestral group than the Chromadorea, and researchers have referred to its members as the "ancestrally diverged nematodes", compared to the "more recently diverged nematodes" of Chromadorea.
Leo Margolis, was a Canadian parasitologist. He was a pioneer in the use of parasites for identification of Pacific Ocean fish stocks. His discoveries became a crucial point in negotiations over pacific salmon fisheries, as it could now be determined where each individual fish spawned, in the rivers of Canada or the United States.
Gongylonema is a genus of thread-like nematode that was described by Molin in 1857. It is the only currently valid genus in the family Gongylonematidae, though the mysterious Spiruroides – usually placed in the Subuluridae, which are not closely related to Gongylonema among the Spiruria – might actually belong here. They are parasites of birds and mammals, transmitted by insects. Some 38 species are known, about 12 of which have been recorded in Europe.
The blacktip grouper, also known as the redbanded grouper, blacktipped cod, black-tipped rockcod, footballer cod, red-barred cod, red-barred rockcod, scarlet rock-cod or weathered rock-cod, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the tropical Indo-Pacific region. It is the type species of the genus Epinephelus.
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.
Lutjanidae, or snappers are a family of perciform fish, mainly marine, but with some members inhabiting estuaries, feeding in fresh water. The family includes about 113 species. Some are important food fish. One of the best known is the red snapper.
The nematodes or roundworms constitute the phylum Nematoda, with plant-parasitic nematodes being known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Taxonomically, they are classified along with insects and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades they have a reduced number of Hox genes, but as their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, it shows that the reduction has occurred within the nematode phylum.
Thelazioidea is a superfamily of spirurian nematodes in the large order Spirurida. Like all nematodes, they have neither a circulatory nor a respiratory system.
Cosmocercoides is a genus of nematode within the order Ascaridida. Nematodes within the genus Cosmocercoides have been found as parasites within the rough-skinned newt, Taricha granulosa. Cosmocercoides includes the following species:
Hassalstrongylus is a genus of nematode worms that infect mostly muroid rodents from eastern North America to South America. The genus is part of the Nippostrongylinae and related to genera like Stilestrongylus.
Pterygodermatites is a genus of parasitic nematodes in the family Rictulariidae. Their life-cycle is complex. Species include:
Huffmanela is a genus of parasitic nematodes, belonging to the family Trichosomoididae.
Philometra is a genus of nematodes, which are parasites of marine and freshwater fishes. The genus was erected by Oronzio Gabriele Costa in 1845.
Cucullanus is a genus of parasitic nematodes. The genus includes more than 100 species.
Günther Osche was a German evolutionary biologist, ecologist and parasitologist.
Heydenius is a collective group genus of fossil nematodes from the Tertiary period that cannot be placed in extant genera.
Physalopteridae is a family of spirurian nematodes, which belongs to the superfamily Physalopteroidea. Like all nematodes, they have neither a circulatory nor a respiratory system.
František Moravec is a Czech parasitologist who specialised on the Nematodes, especially the nematodes parasites of fishes. His research was mainly in the field of taxonomy of the Nematoda.
Cystidicolidae is a family of spirurian nematodes. It was created by Skrjabin in 1946. All members of the family are parasites of fish.
