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.
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.
Pristipomoides filamentosus, the crimson jobfish, rosy snapper, bluespot jobfish, crimson snapper, king emperor, king snapper or rosy jobfish, is a species of ray-finned fish, a snapper belonging to the family Lutjanidae. It is found in the Indian Ocean and in the Pacific Ocean as far east as Hawaii and Tahiti. This species is very important to local commercial fisheries and is sought out as a game fish--one of the Deep Seven species of Hawai'i.
Like humans and other animals, fish suffer from diseases and parasites. Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth. If pathogens breach these defences, fish can develop inflammatory responses that increase the flow of blood to infected areas and deliver white blood cells that attempt to destroy the pathogens.
Paracapillaria is a genus of parasitic nematodes. Species of the genus Paracapillaria parasitise fishes and amphibians, reptiles (snakes), and a single species, Paracapillaria philippinensis(Chitwood, Velasquez & Salazar, 1968), is known from birds and mammals including man.
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.
Anisakis simplex, known as the herring worm, is a species of nematode in the genus Anisakis. Like other nematodes, it infects and settles in the organs of marine animals, such as salmon, mackerels and squids. It is commonly found in cold marine waters, such as the Pacific Ocean and Atlantic Ocean.
Philometra priacanthi is a species of parasitic nematode of fishes. Its name is derived from its host species, Priacanthus hamrur. It possesses dorsal lamella-like structures on the distal part of its gubernaculum, which can also be found on other of its cogenerates. The only species with a dorsal protuberance near the gubernaculum's end is P. priacanthi, however. P. lateolabracis can be distinguished from the former by the lateral caudal mounds separated dorsally, narrower lamella-like structures on its gubernaculum, shorter spicules, and by the testis extending anteriorly. Other gonad-infecting species differ from this one by possessing a smooth gubernaculum, and their spicules being of different lengths. Seven gonad-infecting species of Philometra can be distinguished from P. priacanthi by their host types, as well as by geographical distribution.
Philometra fasciati is a species of parasitic nematode of fishes, first found off New Caledonia in the South Pacific, in the gonads Epinephelus fasciatus. This species is characterized mainly by: length of spicules and length and structure of its gubernaculum; structure of male caudal end; body size; location in host and types of hosts.
Cucullanus is a genus of parasitic nematodes. The genus includes more than 100 species.
František Moravec is a Czech parasitologist who specialises on the Nematodes, especially the nematodes parasites of fishes. His research is 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.
Contracaecum is a genus of parasitic nematodes from the family Anisakidae. These nematodes are parasites of warm-blooded, fish eating animals, i.e. mammals and birds, as sexually mature adults. The eggs and the successive stages of their larvae use invertebrates and increasing size classes of fishes as intermediate hosts. It is the only genus in the family Anisakidae which can infect terrestrial, marine and freshwater animals.
Terranova is a genus of parasitic nematodes. Species from this genus are known to parasitise sharks, rays, sawfishes, teleosts and crocodilians.
Pseudoterranova is a genus within the family Anisakidae of parasitic nematodes with an aquatic life cycle. The lifecycle of Pseudoterranova spp. involves marine mammals, pinnipeds as definitive hosts, planktonic or benthic crustaceans as intermediate hosts and fish which act as second intermediate or paratenic hosts. In some regions, the rise in seal numbers has prefaced a significant increase in fish infected with P. decipiens which is of concern for fish health. Infection with Pseudoterranova may affect the health and swimming ability of the fish host and is therefore of concern for the survival of wild caught and farmed species. Species belonging to this genus have been demonstrated to cause illness of varying exigency in humans if raw or under cooked infected fish is consumed. Cases of human infection have been reported from consuming partially cooked fish infected with Pseudoterranova decipiens, Pseudoterranova cattani and Pseudoterranova azarasi. The propensity of P. decipiens to encyst in the edible portion of fish musculature may make this parasite a considerable threat to human health in undercooked fish.
Hysterothylacium is a genus of parasitic roundworms in the family Raphidascarididae. As of 2020 it consists of over 70 species and is considered one of the largest of the ascaridoid genera parasitising fish.
Euterranova is a genus of parasitic nematodes that have life cycles involving elasmobranchs. The genus was created in 2020 to accommodate species which were previously included inTerranovaLeiper & Atkinson, 1914 a taxon considered to be invalid.
Neoterranova is a genus of parasitic nematodes that have life cycles involving sharks and reptiles. The genus was created in 2020 to accommodate species which were previously included inTerranovaLeiper & Atkinson, 1914 a taxon considered to be invalid.
