Panstrongylus Geniculatus
''Panstrogylus geniculatus'' is a blood-sucking sylvatic insect noted as a putative vector of minor importance in the transmission of ''Trypanosoma cruzi'' to humans; this is a parasite, which causes Chagas disease. The insect is described as sylvatic; subsisting primarily in humid forests, and is also known to inhabit vertebrate nesting places such as those of the armadillo (''dasypus novemcinctus'' or ''dasypus''), and is also involved in enzootic transmission of ''T. cruzi'' to those species. It has wide distribution throughout 16 Latin American countries. There have been few scientific studies of this particular species because of the low number of collected specimens and difficulties in rearing and maintaining populations in the laboratory. However, currently ''P. geniculatus'' is receiving attention as a potential vector of Chagas disease (American trypanosomiasis) due to reports of this species invading the domestic and peridomestic habitats over a vast area: Venezuela, Col ...

Pierre André Latreille
Pierre André Latreille (; 29 November 1762 – 6 February 1833) was a French zoologist, specialising in arthropods. Having trained as a Roman Catholic priest before the French Revolution, Latreille was imprisoned, and only regained his freedom after recognising a rare beetle species he found in the prison, ''Necrobia ruficollis''. He published his first important work in 1796 (), and was eventually employed by the . His foresighted work on arthropod systematics and taxonomy gained him respect and accolades, including being asked to write the volume on arthropods for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomologist of his time, and was described by one of his pupils as "the prince of entomologists". Biography Early life Pierre André Latreille was born on 29 November 1762 in the town of Brive, then in the province of Limousin, as the illegitimate child of Jean Joseph Sahuguet d'Amarzit, général ...

Reduviidae
The Reduviidae are a large cosmopolitan family of the order Hemiptera (true bugs). Among the Hemiptera and together with the Nabidae almost all species are terrestrial ambush predators: most other predatory Hemiptera are aquatic. The main examples of nonpredatory Reduviidae are some blood-sucking ectoparasites in the subfamily Triatominae. Though spectacular exceptions are known, most members of the family are fairly easily recognizable; they have a relatively narrow neck, sturdy build, and a formidable curved proboscis (sometimes called a rostrum). Large specimens should be handled with caution, if at all, because they sometimes defend themselves with a very painful stab from the proboscis. Taxonomy The Reduviidae are members of the suborder Heteroptera of the order Hemiptera. The family members are almost all predatory, except for a few blood-sucking species, some of which are important as disease vectors. About 7000 species have been described, in more than 20 recognized subfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ELISA
The enzyme-linked immunosorbent assay (ELISA) (, ) is a commonly used analytical biochemistry assay, first described by Eva Engvall and Peter Perlmann in 1971. The assay uses a solid-phase type of enzyme immunoassay (EIA) to detect the presence of a ligand (commonly a protein) in a liquid sample using antibodies directed against the protein to be measured. ELISA has been used as a diagnostic tool in medicine, plant pathology, and biotechnology, as well as a quality control check in various industries. In the most simple form of an ELISA, antigens from the sample to be tested are attached to a surface. Then, a matching antibody is applied over the surface so it can bind the antigen. This antibody is linked to an enzyme and then any unbound antibodies are removed. In the final step, a substance containing the enzyme's substrate is added. If there was binding, the subsequent reaction produces a detectable signal, most commonly a color change. Performing an ELISA involves at least ...

Central University Of Venezuela
The Central University of Venezuela (Spanish: ''Universidad Central de Venezuela''; UCV) is a public university of Venezuela located in Caracas. It is widely held to be the highest ranking institution in the country, and it also ranks 18th in Latin America. Founded in 1721, it is the oldest university in Venezuela and one of the oldest in the Western Hemisphere. The main university campus, Ciudad Universitaria de Caracas, was designed by architect Carlos Raúl Villanueva and it is considered a masterpiece of urban planning and was declared a World Heritage Site by UNESCO in 2000. History Origins The origin of the university goes back to Friar Antonio González de Acuña (1620–1682), a Spanish Bishop born in present day Peru who studied theology at the Universidad de San Marcos and founded in 1673 the Seminary Saint Rose of Lima in Caracas named after the first Catholic Saint born in the Americas. In the following years, Friar Diego de Baños y Sotomayor broadened the scope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triatominae
The members of the Triatominae , a subfamily of the Reduviidae, are also known as conenose bugs, kissing bugs (so-called from their habit of feeding from around the mouths of people), or vampire bugs. Other local names for them used in The Americas include ''barbeiros'', ''vinchucas'', ''pitos'', ''chipos'' and ''chinches''. Most of the 130 or more species of this subfamily feed on vertebrate blood; a very few species feed on invertebrates. They are mainly found and widespread in the Americas, with a few species present in Asia and Africa. These bugs usually share shelter with nesting vertebrates, from which they suck blood. In areas where Chagas disease occurs (from the southern United States to northern Argentina), all triatomine species are potential vectors of the Chagas disease parasite ''Trypanosoma cruzi'', but only those species that are well adapted to living with humans (such as ''Triatoma infestans'' and ''Rhodnius prolixus'') are considered important vectors.

Rhodnius Prolixus
''Rhodnius prolixus'' is the principal triatomine vector of the Chagas parasite due to both its sylvatic and domestic populations in northern South America as well as to its exclusively domestic populations in Central America. It has a wide range of ecotopes, mainly savanna and foothills with an altitude of between above sea level and temperatures of . Sylvatic ''R. prolixus'', as virtually all ''Rhodnius'' spp., is primarily associated with palm tree habitats and has a wide range of hosts including birds, rodents, marsupials, sloths, and reptiles. The insect was used by Sir Vincent Wigglesworth for the detection of insect hormones. It has been implicated in the transmission of transposons between it and some of its vertebrate hosts, squirrel monkeys and opossums. ''Rhodnius prolixus'' is also known as the kissing bug because it tends to feed on the area around victims' mouths. History ''Rhodnius prolixus'' established itself throughout Central America after specimens that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triatoma Infestans
''Triatoma infestans'', commonly called winchuka or vinchuca in Argentina, Bolivia, Uruguay and Chile, barbeiro in Brazil, chipo in Venezuela and also known as "kissing bug" or "barber bug" in English, is a blood-sucking bug (like virtually all the members of its subfamily Triatominae) and the most important vector of ''Trypanosoma cruzi'' which can lead to Chagas disease. It is widespread in the Southern Cone countries of South America. This region has joined the control intervention called ''Southern Cone Initiative'' managed by the PAHO. During the ''Beagle'' survey voyage, Charles Darwin noted in his journal for 26 March 1835 having "experienced an attack, & it deserves no less a name, of the ''Benchuca'', the great black bug of the Pampas. It is most disgusting to feel soft wingless insects, about an inch long, crawling over ones body; before sucking they are quite thin, but afterwards round & bloated with blood, & in this state they are easily squashed."

Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
