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 animals 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.
The genera of Trichuridae are: [1]
Trichuris trichiura, Trichocephalus trichiuris or whipworm, is a parasitic roundworm that causes trichuriasis when it infects a human large intestine. It is commonly known as the whipworm which refers to the shape of the worm; it looks like a whip with wider "handles" at the posterior end.
Trichuriasis, also known as whipworm infection, is an infection by the parasitic worm Trichuris trichiura (whipworm). If infection is only with a few worms, there are often no symptoms. In those who are infected with many worms, there may be abdominal pain, tiredness and diarrhea. The diarrhea sometimes contains blood. Infections in children may cause poor intellectual and physical development. Low red blood cell levels may occur due to loss of blood.
Lygosoma is a genus of lizards, commonly known as supple skinks or writhing skinks, which are members of the family Scincidae. Lygosoma is the type genus of the subfamily Lygosominae.
Bachia is a genus of lizards that belong to the spectacled lizards family.
Teixeira de Freitas is a city in the extreme south of the Brazilian state of Bahia, on the margins of BR-101 highway, it is one of the largest cities in the state with a population estimated as of 2020 at 162,438 inhabitants in an area of 1,166 km².
The Trichocephalida is an order of parasitic nematodes.
Caetité is a Brazilian municipality in the state of Bahia. It is located in the semi-arid sertão region in the interior of the state. It had an estimated 51,081 inhabitants as of 2020. It covers 2,651.5 square kilometres (1,023.7 sq mi) and is 757 kilometres (470 mi) from the state capital, Salvador. Caetité borders on ten other municipalities, all within Bahia: Igaporã, Guanambi, Pindaí, Licínio de Almeida, Caculé, Ibiassucê, Lagoa Real, Livramento do Brumado, Paramirim, and Tanque Novo.
The soil-transmitted helminths are a group of intestinal parasites belonging to the phylum Nematoda that are transmitted primarily through contaminated soil. They are so called because they have a direct life cycle which requires no intermediate hosts or vectors, and the parasitic infection occurs through faecal contamination of soil, foodstuffs and water supplies. The adult forms are essentially parasites of humans, causing soil-transmitted helminthiasis (STH), but also infect domesticated mammals. The juveniles are the infective forms and they undergo tissue-migratory stages during which they invade vital organs such as lungs and liver. Thus the disease manifestations can be both local and systemic. The geohelminths together present an enormous infection burden on humanity, amounting to 135,000 deaths every year, and persistent infection of more than two billion people.
The Boridae are a small family of beetles with no vernacular common name, though recent authors have coined the name conifer bark beetles. They feed on decaying cambium and require forests with standing dead trees and with intensive forest management some species have become rare and threatened.
Gongylonema is a genus of thread-like nematode that was described by Molin in 1857. It is the only currently valid genus in the family Gongylonematidae, though the mysterious Spiruroides – usually placed in the Subuluridae, which are not closely related to Gongylonema among the Spiruria – might actually belong here. They are parasites of birds and mammals, transmitted by insects. Some 38 species are known, about 12 of which have been recorded in Europe.
Chymases are a family of serine proteases found primarily in mast cells, though also present in basophil granulocytes. Recently, Derakhshan et al. reported that a specific mast cell population expressed trascripts for Mcpt8. They show broad peptidolytic activity and are involved in a variety of functions. For example, chymases are released by mucosal mast cells upon challenge with parasites and parasite antigens promoting an inflammatory response, and chymase mcp1 and mcp2 are used for marker for mast cell degranulation in parasite infection such as Nematode, Trichuris muris Chymases are also known to convert angiotensin I to angiotensin II and thus play a role in hypertension and atherosclerosis.
Trichuris, often referred to as whipworms, 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.
Nectandra is a genus of plant in the family Lauraceae. They are primarily Neotropical, with Nectandra coriacea being the only species reaching the southernmost United States. They have fruit with various medical effects. Sweetwood is a common name for some plants in this genus.
The Recife Law School, now called Law School, Federal University of Pernambuco, is a law school in the city of Recife, Pernambuco state, Brazil.
The butterfly subtribe Euptychiina is a diverse group within the tribe Satyrini, occurring throughout Central and South America, in addition to a few species known from North America. Euptychiina is a predominantly lowland group, with the exception of one Asian taxon Palaeonympha opalinaButler, 1871 and the Andean genus ForsterinariaGray, 1973. The taxon was erected by Lee Denmar Miller.
The Roman Catholic Diocese of Teixeira de Freitas–Caravelas is a diocese located in the cities of Teixeira de Freitas and Caravelas in the Ecclesiastical province of São Salvador da Bahia in Brazil.
Amphisbaena is a genus in the family Amphisbaenidae, commonly known as worm lizards, even though they are not lizards. Over 100 species are placed in this diverse genus.
De Freitas or DeFreitas may refer to:
Trichuris ovis, commonly known as a whipworm, is a nematode belonging to the genus Trichuris. This whipworm species was first discovered in 1795 and is known to infect sheep and goats. These organisms are capable of inhabiting any region that has the aforementioned hosts, as can be attested by the numerous reports of T. ovis findings throughout North and South America, Australia, Europe, and Asia. Information regarding the species' general life cycle and egg development can be seen in the Trichuris page.
Trichuris discolor, commonly known as a whipworm, is a nematode belonging to the genus Trichuris. The species was discovered by Dr. Otto Friedrich Bernhard von Linstow in 1906 and primarily infects cows. However, they can also infect sheep and goats. Like Trichuris ovis, T. discolor is known to be located in any region that their hosts are located. There have been specific reports of this species being found in Japan, Indo-Pakistan, and North America. Information regarding the species' general life cycle and egg development can be seen in the Trichuris page.
