Trichocephalida
The Trichocephalida (Trichinellida or Trichurida in other classifications) is an order of parasitic nematodes. Taxonomy The order Trichocephalida includes, according to modern classifications, the single suborder Trichinellina Hodda, 2007, which itself includes the single superfamily Trichinelloidea Ward, 1907, which itself includes 6 families: * Family Anatrichosomatidae Yamaguti, 1961 (1 genus, 5 species) including the single genus ''Anatrichosoma'' * Family Capillariidae Railliet, 1915Railliet, A. 1915: L'emploi des médicaments dans le traitement des maladies causées par des Nématodes.

Capillariidae
''Capillariidae'' is a family of parasitic nematodes. All its members are parasites in vertebrates when they are in their adult stage. Taxonomy The family Capillariidae was created by Railliet in 1915. It is accepted in the most recent classifications of the Nematoda,Hodda, M. 2011: Phylum Nematoda Cobb 1932. ''In'': Zhang, Z.-Q. (ed.) 2011: Animal biodiversity: an outline of higher-level classification and survey of taxonomic richness. ''Zootaxa'', 3148: 63–95. (paperback) (online editionPDF/ref> in which it is one of the members of the order Trichocephalida. However, ''Capillaria'' and closely related genera are sometimes included in the family Trichinellidae in other classifications. The taxonomy of the Capillariidae is disputed: according to different classifications, the family includes the single genus ''Capillaria'' or 22 different genera ('' Amphibiocapillaria, Aonchotheca, Baruscapillaria, Calodium, Capillaria, Capillostrongyloides, Crocodylocapillaria, Echin ...

Trichuridae
The roundworm family Trichuridae includes the type genus '' Trichuris'' and some less widely known members. They are (after the abolishment of the artificial " Adenophorea" assemblage) placed in subclass Dorylaimia of the class Enoplea; however, the former might be better treated as a class in its own right. That nonwithstanding, their order ( Trichocephalida) has been known under alternate names in the past, namely Trichiurida. The genus ''Trichuris'' is particularly well known for being a common parasite of domestic animal This page gives a list of domesticated animals, also including a list of animals which are or may be currently undergoing the process of domestication and animals that have an extensive relationship with humans beyond simple predation. This includ ...s and less usually humans. Its common name "whipworm" refers to the shape of these worms; they look like whips with wider "handles" at the posterior end.

Stichocyte
Stichocytes are glandular unicellular cells arranged in a row along the posterior portion of the oesophagus, each of which communicates by a single pore with the lumen of the oesophagus. They contain mitochondria, rough endoplasmic reticulum, abundant Golgi apparatuses, and usually 1 of 2 types of secretory granules, α-granules and β-granules, indicating secretory function Chitwood, B.

Trichuris
''Trichuris'', often referred to as whipworms (which typically refers to ''T. trichiura'' only in medicine, and to any other species in veterinary medicine), is a genus of parasitic worms from the roundworm family Trichuridae, which are helminths. The name whipworm refers to the shape of the worm; they look like whips with wider "handles" at the posterior end. The name ''Trichocephalus'' is sometimes used for this genus. Species The genus ''Trichuris'' includes over 20 species, which infect the large intestine of their host, including: * '' Trichuris trichiura'' (sometimes ''Trichocephalus trichiurus'') – causes trichuriasis in humans * '' Trichuris campanula'' (cat whipworm) * '' Trichuris serrata'' (cat whipworm) * '' Trichuris suis'' (pig whipworm) * '' Trichuris muris'' (mouse whipworm) * '' Trichuris vulpis'' (dog whipworm) A new species – as yet unnamed – has been identified in François’ leaf monkey ('' Trachypithecus francoisi'').

Trichina
''Trichinella'' is the genus of parasitic roundworms of the phylum Nematoda that cause trichinosis (also known as trichinellosis). Members of this genus are often called trichinella or trichina worms. A characteristic of Nematoda is the one-way digestive tract, with a pseudocoelom (body cavity made up of only an ectoderm and endoderm). The genus was first recognised in a larval form in 1835. The L1 larvae live in a modified skeletal muscle cell. The adult worms occupy a membrane-bound portion of columnar epithelium, living as intramulticellular parasites of animals, including humans. Infections with this genus have been reported from more than 150 different naturally or experimentally infected hosts. It has been shown to have a worldwide distribution in domestic and/or sylvatic animals. ''Trichinella'' is the smallest human nematode parasite, yet it is also the largest of all intracellular parasites. Oral ingestion of larvae-contaminated tissue is the usual route of infecti ...

Trichosomoididae
The ''Trichosomoididae'' is a family of nematodes. Morphological characteristics The Trichosomoididae, as most nematodes, have an elongate body, vermiform and covered with a cuticle. There is often a cuticular ornamentation in form of cephalic vesicles or bosses. They are 'aphasmidian' nematodes, i.e. they have no phasmids. The Trichosomoididae are small, with sometimes a marked sexual dimorphism, the female being larger than the male. In some cases, the male lives permanently or penetrates deeply in the female uterus. The body is slightly thicker in the posterior end. The anterior part of the oesophagus is short, its posterior part is surrounded by glandular cells called stichocytes, arranged in chain. The spicule and spicular sheath are absent or vestigial in the male. The female has its vulva near the end of the oesophagus and its anus is terminal. Females are oviparous; eggs are thick-shelled, with plugs on both poles. Eggs are embryonated when laid or laid at very ear ...

Order (biology)
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may fol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
