Leishmania Amazonensis
''Leishmania amazonensis'' is a parasite responsible for the disease leishmaniasis. This species has been known to spread by using sandflies Sandfly (or sand fly) is a colloquial name for any species or genus of flying, biting, blood-sucking dipteran (fly) encountered in sandy areas. In the United States, ''sandfly'' may refer to certain horse flies that are also known as "greenhe ... as its vector and a vertebrate as its primary host, just like other species of Leishmania. They have also been known to spread throughout the Brazilian Amazon region due to their ecological niches needed for survival and reproduction. However, when the host is infected, the Leishmania can cause 3 different forms of Leishmaniasis. For this species, it has been known to cause cutaneous leishmaniasis and mucocutaneous leishmaniasis. Cutaneous leishmaniasis is commonly characterized with skin lesions, which can appear localized, or throughout the body. While mucocutaneous leishmaniasis is charact ...

Ralph Lainson
Ralph Lainson OBE, FRS (21 February 1927 – 5 May 2015) was a British parasitologist who studied leishmaniasis in Brazil. He was the first to publish a record of Chagas disease. Life Lainson was born in Upper Beeding, Sussex on 21 February 1927. His father, Charles Harry Lainson was a chemist for Portland Cement and his mother was Annie May née Denyer. He studied at Steyning Grammar School, before enlisting in the army for a short while. Upon leaving the army, Lainson studied at Brighton Technical College before studying at London University earning a BSc in 1951, a PhD in 1955, and a DSc in 1964. He was a lecturer in the London School of Hygiene and Tropical Medicine from 1955 to 1959. Lainson established the Wellcome Trust Parasitology Unit, in the Instituto Evandro Chagas, Belém, Brazil, in 1965 and directed it until the unit was closed in 1992. Under his direction, the unit focussed on parasitic diseases, especially, leishmaniasis. In 1969, Lainson recorded Chagas' disea ...

Jeffrey Jon Shaw
Jeffrey Jon Shaw OBE, FLS, FASTMH (born 12 July 1938) is a British parasitologist who began working in Latin America in 1962. Although officially retired, he is presently Senior Professor at São Paulo University's Biomedical Sciences Institute where he continues his research in its Parasitology Department. Life During World War II he was evacuated and spent his early childhood in the village of Rothley, Leicestershire, whose surrounding countryside became his playground and fostered his love of nature. When the war ended, he returned to Kent, living there until he went to university in London. Since 1965 he has lived and worked in Brazil. Amongst his hobbies are a love of classical music and sailing. He continues to sail and participate in championships. There is a yearly Snipe class trophy in his name at the Brasília Yacht club. Career He gained a BSc in Zoology in 1960 at London University's Queen Mary College (now Queen Mary University) of London and a PhD in 1964 at the ...

Leishmaniasis
Leishmaniasis is a wide array of clinical manifestations caused by parasites of the trypanosome genus ''Leishmania''. It is generally spread through the bite of phlebotomine sandflies, ''Phlebotomus'' and ''Lutzomyia'', and occurs most frequently in the tropics and sub-tropics of Africa, Asia, the Americas, and southern Europe. The disease can present in three main ways: cutaneous, mucocutaneous, or visceral. The cutaneous form presents with skin ulcers, while the mucocutaneous form presents with ulcers of the skin, mouth, and nose. The visceral form starts with skin ulcers and later presents with fever, low red blood cell count, and enlarged spleen and liver. Infections in humans are caused by more than 20 species of ''Leishmania''. Risk factors include poverty, malnutrition, deforestation, and urbanization. All three types can be diagnosed by seeing the parasites under microscopy. Additionally, visceral disease can be diagnosed by blood tests. Leishmaniasis can be partl ...

Sandfly
Sandfly (or sand fly) is a colloquial name for any species or genus of flying, biting, blood-sucking dipteran (fly) encountered in sandy areas. In the United States, ''sandfly'' may refer to certain horse flies that are also known as "greenheads" (family Tabanidae), or to members of the family Ceratopogonidae. The bites usually result in a small, intensely itchy bump or welt, the strength of which intensifies over a period of 5-7 days before dissipating. Moderate relief is achieved with varying success through the application of over the counter products such as Benadryl (ingested) or an analgesic cream such as After Bite (applied topically). Outside the United States, ''sandfly'' may refer to members of the subfamily Phlebotominae within the Psychodidae. Biting midges (Ceratopogonidae) are sometimes called sandflies or no-see-ums (no-see-em, noseeum). New Zealand sandflies are in the genus ''Austrosimulium'', a type of black fly. In the various sorts of sandfly only the fema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trypanosomatida
Trypanosomatida is a group of kinetoplastid excavates distinguished by having only a single flagellum. The name is derived from the Greek ''trypano'' (borer) and ''soma'' (body) because of the corkscrew-like motion of some trypanosomatid species. All members are exclusively parasitic, found primarily in insects. A few genera have life-cycles involving a secondary host, which may be a vertebrate, invertebrate or plant. These include several species that cause major diseases in humans. Some trypanosomatida are intracellular parasites, with the important exception of Trypanosoma brucei. Medical importance The three major human diseases caused by trypanosomatids are; African trypanosomiasis (sleeping sickness, caused by ''Trypanosoma brucei'' and transmitted by tsetse flies), South American trypanosomiasis (Chagas disease, caused by '' T. cruzi'' and transmitted by triatomine bugs), and leishmaniasis (a set of trypanosomal diseases caused by various species of ''Leishmania'' trans ...
