1. 1. Avian Influenza Virus : Deciphering receptor interactions and their role in interspecies transmission

   Författare :Per Eriksson; Patrik Ellström; Björn Olsen; Josef D. Järhult; Åke Lundkvist; Jonas Waldenström; Hans-Dieter Klenk; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; birds; glycobiology; glycovirology; host range; mixing vessel; virus attachment; Medical Virology; Medicinsk virologi;

   Sammanfattning : Influenza A virus (IAV) annually infects approximately 5–15 % of the human population, causing ~500,000 deaths globally. Novel IAVs have emerged and spread pandemically in the human population, but have over time established endemic circulation with reduced pathogenicity causing seasonal influenza. The natural reservoir of IAVs is wild waterfowl. LÄS MER

3. 2. Ticks and Tick-borne Encephalitis Virus : From Nature to Infection

   Författare :Naveed Asghar; Magnus Johansson; Patrik Dinnétz; Travis Taylor; Södertörns högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Co-occurrence; Environmental factors; Flavivirus; Ixodes ricinus; Natural foci; Non-coding region; Poly A tract; Quasispecies; Questing ticks; Scandinavia; Tick-borne encephalitis virus; Vegetation.; Environmental Studies; Miljövetenskapliga studier;

   Sammanfattning : Vector-borne diseases are an increasing global threat to humans due to climate changes, elevating the risk of infections transmitted by mosquitos, ticks, and other arthropod vectors. Ixodes ricinus, a common tick in Europe, transmits dangerous tick-borne pathogens to humans. LÄS MER

4. 3. TRANSMISSION AND PATHOGENESIS OF HANTAVIRUS

   Författare :Lisa Pettersson; Magnus Evander; Clas Ahlm; Annika Allard; Tatjana Avšič - Županc; Umeå universitet; []
   Nyckelord :Puumala virus; Hantavirus; human-to-human transmission; saliva; nephropathia epidemica; NE; IgA; IgG; IgM; neutrophils; neutrophil; viremia; treatment; climate; snow cover; temperature.; medicinsk virologi; Medical Virology;

   Sammanfattning : Hantaviruses are the causative agents of hemorrhagic fever with renal syndrome (HFRS) in Eurasia, and of hantavirus cardiopulmonary syndrome (HCPS) in the Americas. Transmission to humans usually occurs by inhalation of aerosolized virus-contaminated rodent excreta. LÄS MER

5. 4. 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

7. 5. Hepatitis E virus in the virome of water and animals

   Författare :Hao Wang; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pig; wild boar; wastewater; tap water; enteric virus; NGS;

   Sammanfattning : This thesis was aimed to investigate viruses in different animals and water to get some understanding of viruses that disseminate into the environment. Next generation sequencing (NGS) was used to explore the virome from raw to treated water at two Swedish drinking water treatment plants (DWTP) and in tap water. LÄS MER
