1. 1. Clearing up Culex Confusion : A Basis for Virus Vector Discrimination in Europe

   Författare :Jenny C. Hesson; Jan O. Lundström; Örjan Östman; Åke Lundkvist; Anssi Laurila; Laura D Kramer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Culex torrentium; Culex pipiens; mosquitoes; vector; ornithophilic; Sindbis virus; West Nile virus; Populationsbiologi; Population Biology;

   Sammanfattning : Mosquito species of the Culex genus are the enzootic vectors for several bird-associated viruses that cause disease in humans. In Europe, these viruses include Sindbis (SINV), West Nile and Usutu viruses. The morphologically similar females of Cx. torrentium and Cx. LÄS MER

3. 2. Seroepidemiology of vaccine-preventable and emerging RNA viruses in Rwanda

   Författare :Eric Seruyange; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Seroprevalence; measles virus; rubella virus; Zika virus; West Nile virus; chikungunya virus; tick-borne encephalitis virus; mosquitoes; linear epitopes; Rwanda; Sweden;

   Sammanfattning : Abstract Infectious diseases are a leading cause of death in sub-Saharan Africa, and in Rwanda diarrhea, lower respiratory and other common infections are linked to high mortality and morbidity. For children ... LÄS MER

4. 3. Climate Change, Dengue and Aedes Mosquitoes : Past Trends and Future Scenarios

   Författare :Jing Liu-Helmersson; Joacim Rocklöv; Åke Brännström; Eduardo Massad; Richard Paul; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dengue; mathematical modelling; vectorial capacity; DTR; Aedes aegypti; Aedes albopictus; climate change; Europe; vector invasion; abundance; dengue; matematisk modellering; vektorkapacitet; DTR; Aedes aegypti; Aedes albopictus; klimatförändring; Europa; vektor invasion; epidemiologi; Epidemiology;

   Sammanfattning : Background Climate change, global travel and trade have facilitated the spread of Aedes mosquitoes and have consequently enabled the diseases they transmit (dengue fever, Chikungunya, Zika and yellow fever) to emerge and re-emerge in uninfected areas. Large dengue outbreaks occurred in Athens in 1927 and in Portuguese island, Madeira in 2012, but there are almost no recent reports of Aedes aegypti, the principal vector, in Europe. LÄS MER

5. 4. Mosquitoes as a Part of Wetland Biodiversity

   Författare :Martina Schäfer; Jacob Höglund; Jan Lundström; Darold Batzer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; diversity patterns; species assemblages; functional groups; constructed wetlands; dytiscids; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Sammanfattning : Wetlands contain both aquatic and terrestrial environments which generates high biodiversity. However, they are commonly associated with mosquitoes (Diptera: Culicidae), and mosquitoes are usually regarded as negative by humans because they can cause nuisance and transmit diseases. LÄS MER

7. 5. Selective inhibition of acetylcholinesterase 1 from disease-transmitting mosquitoes : design and development of new insecticides for vector control

   Författare :Cecilia Engdahl; Anna Linusson; Fredrik Ekström; Zoran Radić; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acetylcholinesterase; non-covalent inhibitor; vector control; insecticide; mosquito; vector-borne disease; high throughput screening; rational design; biokemi; Biochemistry; datorlingvistik; computational linguistics;

   Sammanfattning : Acetylcholinesterase (AChE) is an essential enzyme with an evolutionary conserved function: to terminate nerve signaling by rapid hydrolysis of the neurotransmitter acetylcholine. AChE is an important target for insecticides. LÄS MER
