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.

Linshcosteusinii
''Linshcosteus'' is a genus of assassin bugs in the subfamily Triatominae (the kissing bugs). It is the only genus of Triatomines restricted to the Old World within the mostly Neotropical subfamily Triatominae (a few ''Triatoma'' species are known from the Old World and one New World species '' Triatoma rubrofasciata'' has been spread by humans across the tropics) and consists of six species restricted to peninsular India. Within the Triatominae, the genus is differentiated by the lack of a prosternal stridulatory furrow and a short rostrum that does not reach the prosternum. Adults feed on vertebrate blood. The head is cylindrical and as long as the pronotum and scutellum combined. The is a sinuate constriction behind the eye. The portion in front of the head is nearly three times the length of the portion behind. The antennae are closer to the tip than to the eye and the first joint of the antenna reaches just short of the tip of the head while the second segment is as long as ...

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] |
Vinchuca
''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."

Trypanosoma Cruzi
''Trypanosoma cruzi'' is a species of parasitic euglenoids. Among the protozoa, the trypanosomes characteristically bore tissue in another organism and feed on blood (primarily) and also lymph. This behaviour causes disease or the likelihood of disease that varies with the organism: Chagas disease in humans, dourine and surra in horses, and a brucellosis-like disease in cattle. Parasites need a host body and the haematophagous insect triatomine (descriptions "assassin bug", "cone-nose bug", and "kissing bug") is the major vector in accord with a mechanism of infection. The triatomine likes the nests of vertebrate animals for shelter, where it bites and sucks blood for food. Individual triatomines infected with protozoa from other contact with animals transmit trypanosomes when the triatomine deposits its faeces on the host's skin surface and then bites. Penetration of the infected faeces is further facilitated by the scratching of the bite area by the human or animal host. Life ...

Anaphylaxis
Anaphylaxis is a serious, potentially fatal allergic reaction and medical emergency that is rapid in onset and requires immediate medical attention regardless of use of emergency medication on site. It typically causes more than one of the following: an itchy rash, throat closing due to swelling which can obstruct or stop breathing; severe tongue swelling which can also interfere with or stop breathing; shortness of breath, vomiting, lightheadedness, loss of consciousness, low blood pressure, and medical shock. These symptoms typically start in minutes to hours and then increase very rapidly to life-threatening levels. Urgent medical treatment is required to prevent serious harm or death, even if the patient has used an epipen or has taken other medications in response, and even if symptoms appear to be improving. Common causes include allergies to insect bites and stings, allergies to foods – including nuts, milk, fish, shellfish, eggs and some fresh fruits or dried fruits; a ...

Carlos Chagas
Carlos Justiniano Ribeiro Chagas, or Carlos Chagas (; July 9, 1879 – November 8, 1934), was a Brazilian sanitary physician, scientist, and bacteriologist who worked as a clinician and researcher. He discovered Chagas disease, also called ''American trypanosomiasis'', in 1909, while he was working at the Oswaldo Cruz Institute in Rio de Janeiro. Chagas's work holds a unique place in the history of medicine. Working in primitive conditions, Chagas described in detail a previously-unknown infectious disease, its pathogen, vector (Triatominae), host, clinical manifestations, and epidemiology. Chagas was also the first to discover and illustrate the parasitic fungal genus ''Pneumocystis'', which later became infamous for being linked to pneumocystis pneumonia in AIDS patients. Early life Chagas was the son of José Justiniano das Chagas, a coffee farmer from Minas Gerais, and Mariana Cândida Chagas, both of Portuguese descent. After his secondary studies at Itu, São Paulo and S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chagas Disease
Chagas disease, also known as American trypanosomiasis, is a tropical parasitic disease caused by ''Trypanosoma cruzi''. It is spread mostly by insects in the subfamily ''Triatominae'', known as "kissing bugs". The symptoms change over the course of the infection. In the early stage, symptoms are typically either not present or mild, and may include fever, swollen lymph nodes, headaches, or swelling at the site of the bite. After four to eight weeks, untreated individuals enter the chronic phase of disease, which in most cases does not result in further symptoms. Up to 45% of people with chronic infections develop heart disease 10–30 years after the initial illness, which can lead to heart failure. Digestive complications, including an enlarged esophagus or an enlarged colon, may also occur in up to 21% of people, and up to 10% of people may experience nerve damage. is commonly spread to humans and other mammals by the bite of a kissing bug. The disease may also be spr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
