Setaria (roundworm)
''Setaria'' is a genus of parasitic roundworms that infect domesticated mammals such as pigs, camels, cattle and horses. Some species also infect wild mammals such as deer and antelope. The genus consists of about 43 species. Members of the genus are uniquely parasites in the abdominal cavity of the body. They are mostly large-sized roundworms, possessing an elaborate head (cephalic) region that is characterised by spines, presence of four lips, and well-guarded mouth. Little is known about their pathogenic effects, but some are known to affect nervous system and eye. The larval infective forms are transmitted from one animal to another by the bite of mosquitoes and flies. In addition ''Setaria marshalli'' can be transmitted from the womb to new-born calf. A rare case of human infection was recorded in 2016 from a 15-year-old Iranian girl, who was diagnosed with ''Setaria equina'' in her eye. Species Some important species of the genus are: *'' Setaria cervi'' which are parasite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Setaria Graberi
''Setaria'' is a widespread genus of plants in the Poaceae, grass family. The name is derived from the Latin word ''seta'', meaning "bristle" or "hair", which refers to the bristly spikelets.

Aedes
''Aedes'' is a genus of mosquitoes originally found in tropical and subtropical zones, but now found on all continents except perhaps Antarctica. Some species have been spread by human activity: ''Aedes albopictus'', a particularly invasive species, was spread to the New World, including the United States, in the 1980s, by the used-tire trade. First described and named by German entomologist Johann Wilhelm Meigen in 1818, the generic name comes from the Ancient Greek ἀηδής, ''aēdēs'', meaning "unpleasant" or "odious". The type species for ''Aedes'' is ''Aedes cinereus''.. Systematics and phylogeny The genus was named by Johann Wilhelm Meigen in 1818. The generic name comes from the Ancient Greek ἀηδής, ''aēdēs'', meaning "unpleasant" or "odious". As historically defined, the genus contains over 700 species (see the list of ''Aedes'' species). The genus has been divided into several subgenera (''Aedes'', '' Diceromyia'', '' Finlaya'', ''Stegomyia'', etc.) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mouse-deer
Chevrotains, or mouse-deer, are small even-toed ungulates that make up the family Tragulidae, the only extant members of the infraorder Tragulina. The 10 extant species are placed in three genera, but several species also are known only from fossils. The extant species are found in forests in South and Southeast Asia, with a single species, the water chevrotain, in the rainforests of Central and West Africa. They are solitary or live in pairs, and feed almost exclusively on plant material. Chevrotains are the smallest hoofed mammals in the world. The Asian species weigh between , while the African chevrotain is considerably larger at . With an average length of and an average height of , the Java mouse-deer is the smallest extant (living) ungulate or hoofed mammal, as well as the smallest extant even-toed ungulate. In November 2019, conservation scientists announced that they had photographed silver-backed chevrotains (''Tragulus versicolor'') in a Vietnamese fores ...

Anopheles Sinensis
''Anopheles sinensis'' is a species of mosquito that transmits malaria as well as lymphatic filariasis. It is regarded as the most important vector of these human parasitic diseases in Southeast Asia. It is the primary vector of vivax malaria (''Plasmodium vivax'') in many regions. In China it also transmits the filalarial parasite (''Wuchereria bancrofti''), and arthropod roundworm (''Romanomermis jingdeensis''). In Japan it is also a vector of a roundworm ''Setaria digitata'' in sheep and goats. Because of its similarity with other ''Anopheles'', it is now considered a species complex comprising at least four species. Its genome was sequenced in 2014. Taxonomy and description ''An. sinensis'' is classified as a species complex, and is a member of ''An. hyrcanus'' group. The group is distinguished from other groups by the presence of pale bands (usually four) on the palpi and by the presence of a tuft of dark scales on the clypeus on each side in the female adult.

Anopheles
''Anopheles'' () is a genus of mosquito first described and named by J. W. Meigen in 1818. About 460 species are recognised; while over 100 can transmit human malaria, only 30–40 commonly transmit parasites of the genus ''Plasmodium'', which cause malaria in humans in endemic areas. '' Anopheles gambiae'' is one of the best known, because of its predominant role in the transmission of the most dangerous malaria parasite species (to humans) – '' Plasmodium falciparum''. The name comes from the Ancient Greek word 'useless', derived from , 'not', 'un-' and 'profit'. Mosquitoes in other genera (''Aedes'', ''Culex'', '' Culiseta'', '' Haemagogus'', and ''Ochlerotatus'') can also serve as vectors of disease agents, but not human malaria. Evolution The ancestors of ''Drosophila'' and the mosquitoes diverged . The culicine and ''Anopheles'' clades of mosquitoes diverged between and . The Old and New World ''Anopheles'' species subsequently diverged between and . '' Anophel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culex
''Culex'' is a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals. The diseases they vector include arbovirus infections such as West Nile virus, Japanese encephalitis, or St. Louis encephalitis, but also filariasis and avian malaria. They occur worldwide except for the extreme northern parts of the temperate zone, and are the most common form of mosquito encountered in some major U.S. cities, such as Los Angeles. Etymology In naming this genus, Carl Linnaeus appropriated the nonspecific Latin term for a midge or gnat: '. Description Depending on the species, the adult ''Culex'' mosquito may measure from . The adult morphology is typical of flies in the suborder Nematocera with the head, thorax, and abdomen clearly defined and the two forewings held horizontally over the abdomen when at rest. As in all Diptera capable of flight, the second pair of wings is reduced and modified into tiny, incon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antelope
The term antelope is used to refer to many species of even-toed ruminant that are indigenous to various regions in Africa and Eurasia. Antelope comprise a wastebasket taxon defined as any of numerous Old World grazing and browsing hoofed mammals belonging to the family Bovidae of the order Artiodactyla. A stricter definition, also known as the "true antelopes," includes only the genera ''Gazella'', ''Nanger'', ''Eudorcas'' and ''Antilope''. One North American species, the pronghorn, is colloquially referred to as the "American antelope," but it belongs to a different family from the African and Eurasian antelopes. A group of antelope is called a herd. Unlike deer antlers, which are shed and grown annually, antelope horns grow continuously. Etymology The English word "antelope" first appeared in 1417 and is derived from the Old French ''antelop'', itself derived from Medieval Latin ''ant(h)alopus'', which in turn comes from the Byzantine Greek word ἀνθόλοψ, ''anthó ...
