Capsalidae
Capsalidae Yamaguti, S. (1963) Systema Helminthum IV. Monogenea and Aspidocotylea. London-New York, Interscience Publishers. 699 pp. is a family of monopisthocotylean monogeneans, which includes about 200 species. The monophyly of the Capsalidae is supported by possession of accessory sclerites in the haptor (the posterior attachment organ), and was confirmed by molecular phylogeny. Their oncomiracidium (the free larva) is distinct from that of other families. Capsalids are parasite on various organs of marine fish ( teleosts and elasmobranchs), including skin, fins and gills. Several capsalid species, such a '' Neobenedenia'' spp. are pathogenic, especially on maricultured fish. Included genera Genera as recognized iWorMsare listed below. Recent molecular analyses have shown that several genera, which were defined on morphological characters, are not monophyletic. '' Menziesia'' and '' Nitzschia'' have their equivalent in the botanical nomenclature: '' Menziesia'' (a flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satyu Yamaguti
was a Japanese parasitologist, entomologist, and helminthologist. He was a specialist of mosquitoes and helminths such as digeneans, monogeneans, cestodes, acanthocephalans and nematodes. He also worked on the parasitic crustaceans Copepoda and Branchiura. Satyu Yamaguti wrote more than 60 scientific papersAnonymous. 1983. Special edition: A list of papers by Dr. Satyu Yamaguti and his collaborators and a notice on their distribution. The Meguro Parasitological Museum News, 153 (58), 1-12PDF and, more importantly, several huge monographs which are still in use by scientists all over the world and were cited over 1,000 times each. Education and career Satyu Yamaguti was born in Nagano Prefecture, Japan, 21 April 1894. He graduated from Okayama Medical College (1918), studied pathology at Tokyo University (1918-1925) and parasitology at the Institut für Tropenkrankheiten in Hamburg, Germany (1925-1926). He received his MD from Tokyo University in 1926 and was Dr. Sc. of Kyoto U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monopisthocotylea
The Monopisthocotylea are an inferior class of parasitic flatworms in the class Monogenea.WoRMS (2019). Monopisthocotylea. Accessed at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=119219 on 2019-02-08 Yamaguti, S. (1963). Systema Helminthum Volume IV Monogenea and Aspidocotylea: John Wiley & Sons.Hayward, C. (2005). Monogenea Polyopisthocotylea (ectoparasitic flukes). In K. Rohde (Ed.), Marine Parasitology (pp. 55-63): CSIRO, Collingwood, Australia & CABI, Oxon, UK. Classification There are only two inferior classes in the class Monogenea: * Monopisthocotylea. The name means "a huge sucker" - the attachment organ (the haptor) is simple. * Polyopisthocotylea. The name means "a little sucker" - the attachment organ (the haptor) is complex, with several clamp (zoology), clamps or sucker (zoology), suckers. The inferior class Monopisthocotylea contains these orders: * Order Capsalidea * Order Dactylogyridea * Order Gyrodactylidea * Order Monocotylidea * Order Montchadskye ...

Monogenea
Monogeneans, members of the class Monogenea, are a group of ectoparasitic flatworms commonly found on the skin, gills, or fins of fish. They have a direct lifecycle and do not require an intermediate host. Adults are hermaphrodites, meaning they have both male and female reproductive structures.L.A. Tubbsa et al. (2005). "Effects of temperature on fecundity in vitro, egg hatching and reproductive development of ''Benedenia seriolae'' and ''Zeuxapta seriolae'' (Monogenea) parasitic on yellowtail kingfish Seriola lalandi". ''International Journal for Parasitology''(35), 315–327. Some monogeneans are oviparous (egg-laying) and some are viviparous (live-bearing). Oviparous varieties release eggs into the water. Viviparous varieties release larvae, which immediately attach to another host. The genus ''Gyrodactylus'' is an example of a viviparous variety, while the genus ''Dactylogyrus'' is an example of an oviparous variety. Signs and symptoms Freshwater fish that become infect ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Fish Parasites
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. Specific defences are specialised responses to particular pathogens recognised by the fish's body, that is adaptative immune responses. In recent years, vaccines have become widely used in aquaculture and ornamental fish, for example vaccines for commercial food fishes like Aeromonas salmonicida, furunculosis in salmon and Lactococcosis\Streptococcosis in farmed grey mullet, Tilapia and koi herpes virus in koi. Some commercially important fish diseases are VHS, ICH, and whirling disease. Parasites ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
