Alexandr Vladimirovich Gussev
Alexandr Vladimirovich Gussev (Александр Владимирович Гусев, 5 July 1917 – 31 December 1999), sometimes spelled Gusev in the literature, was a Russian helminthologist specialist of monogeneans. Gussev was a student of the soviet parasitologist V. A. Dogiel. He worked at the Zoological Institute in Leningrad, then Saint Petersburg, Russia. He received his PhD in 1953 and his DrSc in 1973. Gussev wrote more than 220 publications, dealing with systematics, faunistics, morphology, development, biology and zoogeography of fish parasites. Gussev is mainly known for his work on the Monogenea, a group of Platyhelminthes parasitic on freshwater and marine fish. He was one of the world leader in this field and described more than 200 new species of monogeneans. He also authored a handbook on methods of collecting monogeneans.

Dactylogyrus
''Dactylogyrus'' is a genus of monogeneans in the Dactylogyridae family. Like other monogeneans, species of ''Dactylogyrus'' only have one host required to complete their life cycle. Introduction Members of ''Dactylogyrus'' (common name: Gill Fluke) are oviparous (egg-laying) monogeneans trematodes that have two pairs of anchors. These anchors can be used to latch onto the gills of a host, particularly freshwater fish such as carp. In heavily infected fish, ''Dactylogyrus'' can also be found on the buccal cavity, and at times fins and skin of the freshwater fish. Species ''Dactylogyrus'' is one of the most speciose genus of helminths, with more than 900 species described. Consequently, in 1996, it was estimated that the taxonomy was "in a state of considerable confusion". Anatomy Other characteristics of ''Dactylogyrus'' species include the appearance of four eye-spots, 14 marginal hooks (7 pairs), one to two connective bars and two needle-like structures and spindle-sh ...

Monogenea
Monogeneans 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 infected with this parasite become let ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monopisthocotylea
The Monopisthocotylea are a subclass of parasitic flatworms in the class Monogenea. WoRMS (2019). Monopisthocotylea.

(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 subclasses in the class Monogenea: * Monopisthocotylea. The name means "a single posterior sucker" - the attachment organ (the haptor) is simple. * Polyopisthocotylea. The name means "several posterior suckers" - the attachment organ (the haptor) is complex, with several clamps or suckers. The subclass Monopisthocotylea contains these orders: * Order Capsalidea * Order Dactylogyridea * Order Gyrodactylidea * Order Monocotylidea * Order Montchadskyellidea Example of species * ...

Flatworm
The flatworms, flat worms, Platyhelminthes, or platyhelminths (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates (having no body cavity), and have no specialized circulatory and respiratory organ (anatomy), organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both ingestion (intake of nutrients) and egestion (removal of undigested wastes); as a result, the food cannot be processed continuously. In traditional medicinal texts, Platyhelminthes are divided into Turbellaria, which are mostly non-parasitic animals such as planarians, and three entirely parasitic groups: Cestoda, Trematoda and Monogenea; however, since the turbellarians have since been prove ...

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
