Karl Asmund Rudolphi was a Swedish-born German naturalist, who is credited with being the "father of helminthology".
Galactosomum is a genus of flukes in the family Heterophyidae. There are currently 28 recognised species within the genus. They mainly infect aquatic birds, but often infest fish as larvae. Three species are known to use marine mammals as hosts.
The blue bird-of-paradise is a beautiful, relatively large species of bird-of-paradise. It is the only species in the genus Paradisornis, but was previously included in the genus Paradisaea.
The thorny-headed worm family Polymorphidae contains endoparasites which as adults feed mainly in fish and aquatic birds. When this taxon was erected by Meyer in 1931, a subfamily Polymorphinae was established in it. As the Polymorphidae as presently understood would then be monotypic, with no basal genera outside the Polymorphinae, the proposed subfamily is redundant for the time being and therefore most modern treatments simply omit it. Polymorphus minutus is an economically significant parasite in goose and duck farming.
Oligacanthorhynchida is an order containing a single parasitic worm family, Oligacanthorhynchidae, that attach themselves to the intestinal wall of terrestrial vertebrates.
Litozamia is a genus of sea snails, marine gastropod mollusks in the subfamily Trophoninae of the family Muricidae, the murex snails or rock snails.
Eustrongylidosis is a parasitic disease that mainly affects wading birds worldwide; however, the parasite's complex, indirect lifecycle involves other species, such as aquatic worms and fish. Moreover, this disease is zoonotic, which means the parasite can transmit disease from animals to humans. Eustrongylidosis is named after the causative agent Eustrongylides, and typically occurs in eutrophicated waters where concentrations of nutrients and minerals are high enough to provide ideal conditions for the parasite to thrive and persist. Because eutrophication has become a common issue due to agricultural runoff and urban development, cases of eustrongylidosis are becoming prevalent and hard to control. Eustrongylidosis can be diagnosed before or after death by observing behavior and clinical signs, and performing fecal flotations and necropsies. Methods to control it include preventing eutrophication and providing hosts with uninfected food sources in aquaculture farms. Parasites are known to be indicators of environmental health and stability, so should be studied further to better understand the parasite's lifecycle and how it affects predator-prey interactions and improve conservation efforts.
Philometra is a genus of nematodes, which are parasites of marine and freshwater fishes. The genus was erected by Oronzio Gabriele Costa in 1845.
Peracreadium is a genus of trematodes in the family Opecoelidae. It is very similar to the related genus Cainocreadium Nicoll, 1909, and has been synonymised with the genera Anabathycreadium Salman & Srivastava, 1990, Indocreadium Salman & Srivastava, 1990, and Lebouria Nicoll, 1909.
Echinostomatidae is a family of trematodes in the order Plagiorchiida, first described in 1899.
Ichthyocotylurus is a genus of flatworms belonging to the family Strigeidae.
Triaenophorus is a genus of flatworms belonging to the family Triaenophoridae.
Dioctophymidae is a family of nematodes belonging to the order Ascaridida. Much older literature uses the alternative spelling "Dioctophymatidae" but this alternative spelling was suppressed by the ICZN in a 1987 ruling.
Diorchis is a genus of flatworms belonging to the family Hymenolepididae.
Bothriocephalus is a genus of flatworms belonging to the family Bothriocephalidae.
Amidostomum is a genus of nematodes belonging to the family Amidostomatidae.
Dichelyne is a genus of nematodes belonging to the family Cucullanidae.
Tetrabothrius is a genus of flatworms belonging to the family Tetrabothriidae.
Oxyuris is a genus of nematodes belonging to the family Oxyuridae.
Echinostomatinae is a subfamily of trematodes in the order Plagiorchiida, first described in 1899.
