Walborg Thorsell
Walborg Susanna Thorsell (12 February 1919 – January 2016) was a Swedish scientist who performed research mainly on mosquitoes and mosquito repellents. Education Thorsell defended her thesis for her doctorate in veterinary medicine at the Swedish Veterinarian Institute in 1967, and was a docent in experimental parasitology. Research Thorsell started her studies on mosquitoes while working at the Swedish National Defence Research Institute (FOA). At that time claims circulated, from both the United States and the Soviet Union, that the other part was conducting experiments with malaria mosquitos in relations to biological warfare. The Swedish military therefore felt it necessary to develop a mosquito repellent, especially for malaria mosquitoes, to be used by Swedish soldiers. The existing repellents were either not efficient enough or had unwanted side effects, so Thorsell and her group of researchers at FOA began looking for a better agent. The substance ''diethylamid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosquito
Mosquitoes, the Culicidae, are a Family (biology), family of small Diptera, flies consisting of 3,600 species. The word ''mosquito'' (formed by ''Musca (fly), mosca'' and diminutive ''-ito'') is Spanish and Portuguese for ''little fly''. Mosquitoes have a slender segmented body, one pair of wings, three pairs of long hair-like legs, and specialized, highly elongated, piercing-sucking mouthparts. All mosquitoes drink nectar from flowers; females of some species have in addition adapted to drink blood. The group diversified during the Cretaceous period. Evolutionary biology, Evolutionary biologists view mosquitoes as micropredators, small animals that Parasitism, parasitise larger ones by drinking their blood without immediately killing them. Parasitology, Medical parasitologists view mosquitoes instead as Disease vector, vectors of disease, carrying protozoan parasites or bacterial or virus, viral pathogens from one Host (biology), host to another. The mosquito life cycle cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thorselliaceae
Thorselliaceae is a family of bacteria belonging to the class Gammaproteobacteria and it was first described in February 2015. It is not assigned to an order. The family consists of four species in two genera. The bacteria are Gram-negative and rod shaped, approximately 1 μm wide and 2 μm long. They are facultative anaerobes and motile. Thorselliaceae bacteria have been found around the world associated with vector mosquitoes, mainly with vectors of malaria. The first described species was ''Thorsellia anophelis''. It was isolated from the midgut of the malaria mosquito '' Anopheles arabiensis'' from Kenya. This new bacterium was given its name after the Swedish researcher Walborg Thorsell who worked with mosquitoes and insecticides against mosquitoes for many years. ''Thorsellia'' bacteria have now been found in mosquito species that are the major vectors of malaria in Africa, Asia and South America. The bacteria have also been found in the waters where the malaria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swedish Defence Research Agency
The Swedish Defence Research Agency (, FOI; literal translation: ''Total Defence Research Institute'') is a government agency in Sweden for total defence research and development. FOI has its headquarters in Kista (Stockholm). Other FOI offices or research centres are located in Grindsjön, Linköping, and Umeå. History FOI was created in 2001 by combining the Swedish National Defence Research Institute (FOA) with the National Aeronautical Research Institute (FFA). The first of these agencies, FFA, had been created in 1940 in Bromma, Stockholm as a governmental research institute for the Swedish aviation industry, large parts of which were devoted to military aircraft. The second, FOA, had been created in 1945 from three existing organisations: * The Swedish Armed Forces Chemical Institute (''Försvarsväsendets kemiska anstalt'', FKA), a government agency created in 1937 and located in Ursvik, Sundbyberg Municipality. FKA had predecessors in chemical warfare and chemical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malaria
Malaria is a Mosquito-borne disease, mosquito-borne infectious disease that affects vertebrates and ''Anopheles'' mosquitoes. Human malaria causes Signs and symptoms, symptoms that typically include fever, Fatigue (medical), fatigue, vomiting, and headaches. In severe cases, it can cause jaundice, Epileptic seizure, seizures, coma, or death. Symptoms usually begin 10 to 15 days after being bitten by an infected ''Anopheles'' mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial Immunity (medical), resistance disappears over months to years if the person has no continuing exposure to malaria. The mosquitoes themselves are harmed by malaria, causing reduced lifespans in those infected by it. Malaria is caused by protozoa, single-celled microorganisms of the genus ''Plasmodium''. It is spread exclusively through bites of infected female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
